(en)This is a division of Application Ser. No. 08/433,522 filed Sep. 12, 1995, which is a National Phase filing from PCT/CA93/00501 filed Nov. 23, 1993.


FIELD OF INVENTION
The present invention is related to the field of molecular genetics and is particularly concerned with the cloning of an outer membrane protein D15 of Haemophilus.
BACKGROUND OF THE INVENTION
Haemophilus influenzae type b (Hib) is a major cause of bacterial meningitis in children under the age of five years. Protective antibodies to the disease are induced by the capsular polysaccharide of the organism and a vaccine was developed that utilises the purified polyribosyl ribitol phosphate (PRP) as the antigen. This vaccine provides 90% protection in adults and in children over 24 months of age, but was ineffective in children under 24 months Zangwill et al 1993 (The references are identified in a list of reference at the end of this disclosure). Like other polysaccharide antigens, PRP does not induce the proliferation of T-helper cells, and re-immunisation fails to elicit either a booster response or an increase in memory cells. Conjugation of the PRP polysaccharide with protein carriers confers T-cell dependent characteristics to the vaccine and substantially enhances the immunologic response to the PRP antigen. Currently, there are four PRP-carrier conjugate vaccines available. These are vaccines based upon H. influenzae type b capsular polysaccharide conjugated to diphtheria toxoid, tetanus toxoid, or Neisseria meningitidis outer membrane protein (reviewed in Zangwill et al 1993).
However, the current Haemophilus conjugate vaccines only protect against meningitis caused by Haemophilus influenzae type b. They do not protect against other invasive typeable strains (types a and c) and, more importantly, against non-typeable (NTHi) strains which are a common cause of postpartum and neonatal sepsis, pneumonia and otitis media. In the United States alone, treatment of otitis media costs between 1 and 2 billion dollars per year for antibiotics and surgical procedures, such as tonsillectomies, adenoidectomies and insertion of tympanostomy tubes. To achieve universal protection against H. influenzae related diseases in the 2 to 6 month age group and certain high risk groups, the provision of conserved, cross-reactive non-capsular H. influenzae immunogens is desirable. Methods for inducing immunity against disease are constantly improving and there is presently a move to use subunits and better defined materials as antigens. This is being undertaken to minimise or eliminate potential side-effects caused by certain native immunogens, while preserving their immunogenicity to confer protection against the disease. Therefore, it would be very attractive to develop a universal vaccine against Haemophilus using cross-reactive outer membrane proteins, fragment, analogs, and/or peptides corresponding thereto as protective antigens. Such antigens may be incorporated into the conventional H. influenzae type b conjugate vaccines as additional immunogens or used as autologous carriers for H. influenzae capsular polysaccharides. A high molecular weight outer membrane protein D15 found in non-typeable and type b stains of H. influenzae has been identified as a cross-reactive antigen (Thomas et al., 1990). D15 appears to be cell surface-exposed in its natural state and exhibits a molecular mass of about 80 kDa as judged by SDS-PAGE analysis. It would be desirable to provide the sequence of the DNA molecule that encodes this D15 outer membrane protein and peptides corresponding to portions thereof for diagnosis, immunization and the generation of diagnostic and immunological reagents. The diseases caused by Haemophilus are serious and improved methods for preventing, detecting and treating diseases such as otitis media, epiglottitis, pneumonia, and tracheobronchitis, are required.
The present invention is directed towards the provision of purified and isolated nucleic acid molecules comprising at least a portion coding for a D15 outer membrane protein of a species of Haemophilus. The nucleic acid molecules comprising at least a portion coding for D15 outer membrane protein are useful for the specific detection of strains of Haemophilus, and for diagnosis of infection by Haemophilus. The purified and isolated nucleic acid molecules, such as DNA comprising at least a portion coding for D15 outer membrane protein, are also useful for expression of the D15 gene by recombinant DNA means for providing, in an economical manner, purified and isolated D15 outer membrane protein.
The D15 outer membrane protein or fragments thereof or analogs thereof are useful immunogenic compositions for the preparation of vaccines against diseases caused by Haemophilus, the diagnosis of infection by Haemophilus and as tools for the generation of immunological reagents. Mono- or polyclonal antisera (antibodies) raised against the D15 outer membrane protein produced in accordance with aspects of the present invention are useful for the diagnosis of infection by Haemophilus, specific detection of Haemophilus (in, for example, in vitro and in vivo assays) and for the treatment of diseases caused by infection by Haemophilus,
Peptides corresponding to portions of the D15 outer membrane protein or analogs thereof are useful immunogenic compositions for the preparation of vaccines against disease caused by Haemophilus, the diagnosis of infection by Haemophilus and as tools for the generation of immunological reagents. Mono- or polyclonal antisera raised against these peptides, produced in accordance with aspects of the present invention, are useful for the diagnosis of infection by Haemophilus, specific detection of Haemophilus (in, for example, in vitro and in vivo assays) and for use in passive immunization as a treatment of disease caused by infection by Haemophilus.

The plasmids may be adapted for expression of the encoded D15 outer membrane protein in a host cell, which may be a heterologous or homologous host, by incorporation into a recombinant vector, provided in accordance with a further aspect of the invention. The recombinant vector may comprise at least a DNA segment comprising at least an 18 bp fragment selected from the DNA molecules as recited above and expression means operatively coupled to the DNA segment for expression of the gene product encoded thereby in the host cell.

GENERAL DESCRIPTION OF THE INVENTION
Any Haemophilus strains that have D15 genes may be conveniently used to provide the purified and isolated nucleic acid molecules (which may be in the form of DNA molecules), comprising at least a portion coding for a D15 outer membrane protein as typified by embodiments of the present invention. Such strains are generally available from clinical sources and from bacterial culture collections, such as the American Type Culture Collection. H. influenzae strains may include types a, b and c strains, non-typeable strains and other bacteria that produce a D15 protein, fragment or analog thereof. Appropriate strains of Haemophilus include:
H. influenzae type b strain Ca;
H. influenzae type b strain MinnA;
H. influenzae type b strain Egan;
H. influenzae non-typeable b strain SB33; or
H. influenzae non-typeable b strain PAK 12085.
In this application, the term D15 outer membrane protein is used to define a family of D15 proteins which includes those having naturally occurring variations in their amino acid sequences as found in various strains of, for example, Haemophilus. The purified and isolated DNA molecules comprising at least a portion coding for D15 outer membrane protein of the present invention also include those having naturally occuring variations in their nucleic acid sequences as found in various strains of, for example Haemophilus and those DNA molecules encoding functional analogs of D15 outer membrane protein. In this application, a first protein is a functional analog of a second protein if the first protein is immunologically related with and/or has the same function as the second protein. The functional analog may be, for example, a fragment of the protein or a substitution, addition or deletion mutant thereof.
In aspects of the present invention, the D15 gene was isolated from H. influenzae type b strain Ca as shown in FIG. 1A; H. influenzae type B Eagan, FIG. 1B; H. influenzae type b MinnA, FIG. 1C; non-typeable H. influenzace SB33, FIG. 1D; non-typeable H. influenzae PAK 12085, FIG. 1E. A comparison of the nucleic acid sequences of the D15 genes and of the deduced amino acid sequences of the D15 outer membrane proteins from these strains of H. influenzae showed the genes and proteins to be highly conserved (FIGS. 1 F and 3 ). The consensus sequence (SEQ ID NO: 55) for the D15 gene is shown in FIG. 1 F.
The purified and isolated DNA molecules comprising at least a portion coding for a D15 outer membrane protein of a species of Haemophilus, typified by the embodiments described herein, are advantageous as:
nucleic acid probes for the specific identification of Haemophilus strains in vitro or in vivo
the products encoded by the DNA molecules are useful as diagnostic reagents, antigens for the production of Haemophilus-specific antisera, for vaccination against the diseases caused by species of Haemophilus and detecting infection by Haemophilus; and
peptides corresponding to portions of the D15 outer membrane protein as typified by the embodiments described herein are advantageous as diagnostic reagents, antigens for the production of Haemophilus-specific antisera, for vaccination against the diseases caused by species of Haemophilus and for detecting infection by Haemophilus.
Reference will now be made in detail to the presently preferred embodiments of the invention, which together with the following Examples, serve to explain the principle of the invention. For clarity of disclosure, and not by way of limitation, the detailed description of the invention is divided into the following sections:
(i) The DNA Sequences Coding for the Outer Membrane Protein D15 from H. influenzae Type b Ca Strain.
A clone producing the outer membrane protein designated D15 of H. influenzae type b (Hib) was isolated by screening a genomic library with H. influenzae type b OMP-specific polyclonal antibodies as previously described by Berns and Thomas 1965; Thomas and Rossi 1986. The DNA fragment encoding the D15 protein was isolated, subcloned into pUC19 to produce pUC19/D15 (FIG. 2) and used to transform E. coli HB101 as described in Example 1. Plasmid DNA was prepared from two individual colonies of E. coli HB101 containing the pUC19/D15 plasmid. Sequencing was performed on an ABI DNA sequencer model 370A using dye-terminator chemistry and oligonucleotide primers which had been synthesized on an ABI DNA synthesizer model 380B, and purified by chromatography. Nucleotide sequence analysis of the D15 gene revealed that it contains a putative promoter and an open reading frame encoding 789 amino acids (FIG. 1 A).
The first 19 amino acid residues of the translated open reading frame form a typical leader sequence as found in other H. influenzae type b outer membrane proteins, such as P1 and P2. The N-terminal sequence of immuno-affinity purified native D15 antigen was determined by automated Edman degradation using the ABI 477A protein sequencer and was found to be Ala-Pro-Phe, which is identical to the N-terminal amino acid sequence Ala-Pro-Phe-Val-Ala-Lys-(SEQ ID NO: 11) predicted from an analysis of the sequence of the D15 gene presented in FIG. 1 A.
(ii) The Sequence pf D15 Genes from Other H. influenzae Strains
D15 genes were isolated from other H. influenzae strains by screening the chromosomal libraries of H. influenzae type b strains Eagan, Minn A and the non-typeable H. influenzae (NTHi) strains SB33 and PAK 12085, as described in Examples 2, 3 and 4. Hybridization-positive clones were plated and submitted to a second round of screening. The restriction maps of the clones obtained are shown in FIG. 2 . The nucleotide sequences of the D15 genes were determined for all these clones (FIGS. 1B to 1 E) and their derived amino acid sequences compared (FIG. 3 ). The D15 amino acid sequences of the three H. influenzae type b strains were identical and only a few amino acid differences were observed in the amino acid sequence of the D15 protein from the non-typeable strains (FIG. 3 ).
(iii) Expression of D15 and its Fragments in E. coli.
Since D15 is expressed in small quantities by strains of H. influenzae , it is advantageous to either express this antigen as a recombinant protein in a heterologous system, such as E. coli , or to modify the H. influenzae organism to enhance native D15 expression. The Hind III/Eco RI fragment of H. influenzae type b Ca strain DNA encoding the full length D15 protein was expressed in pUC19 but not pUC18, suggesting that the lac promoter is helping to express the D15 gene in E. coli , even though the native D15 gene promoter is present. The T7 expression system is a tightly controlled, inducible system which has great utility in expression of heterologous proteins in E. coli The T7 expression system is described in U.S. Pat. No. 4,952,496. Clones were, therefore, constructed which utilize the T7 system to express a mature D15 protein that contains an additional methionine residue at the amino terminus. The D15 signal sequence was removed during this construction process. A full length recombinant D15 (termed rD15) was expressed in inclusion bodies which allow the D15 protein to be readily purified. The D15 genes from H. influenzae type b strain Ca and H. influenzae non-typeable SB33 strain have been expressed at high levels in E. coli using the T7 system to permit production of large quantities of rD15 protein. The construction of clone DS-880-1-2 which expresses the SB33 D15 gene is described herein (see FIG. 4 and Example 5). The rD15 protein was immunologically similar to its native counterpart isolated from H. influenzae typeable and non-typeable strains (see below). Thus, rD15 may be used as a cross-reactive antigen in a diagnostic kit to detect many, if not all, strains of H. influenzae and other bacteria that produce a D15 outer membrane protein or analog thereof. Alternatively, rD15 can be used as an antigen to specifically detect the presence of H. influenzae in a sample.
A truncated D15 fragment was expressed in E. coli as a fusion protein with glutathione S-transferase (GST), as described in Example 6. The construction was designed to express the N-terminal fragment of the D15 protein. The fusion protein was expressed at high levels from a pGEX-2T construction and the N-terminal fragment was cleaved from the GST carrier protein by treatment with thrombin. This procedure generated a molecule termed the N-terminal rD15 fragment which encompasses amino acids 63-223 of the D15 protein. This N-terminal rD15 fragment was highly immunogenic and elicited protective antibodies against challenge with live H. influenzae.
(iv) Purification of Native D15 from H. influenzae Cell Paste.
The present invention also provides a method to prepare purified native D15 protein from H. influenzae . The protein is extracted and affinity-purified from the cell pastes of either H. influenzae typeable or non-typeable isolates by a procedure involving the dissolution of the protein in an aqueous detergent solution (see Example 13). The native D15 protein from a non-typeable H. influenzae strain 30 was solubilized with a 50 mM Tris-HCl/0.5% Triton X-100/10 mM EDTA buffer, pH 8.0 and further purified on a D15-specific monoclonal antibody affinity column (FIG. 5 A). An 80 kDa protein was eluted from the column with 50 mM diethylamine, pH 12.0 and shown to react with a D15-specific monoclonal antibody on immunoblot analysis (FIG. 5 B). The native D15 is also highly immunogenic in experimental animals. Rabbit anti-D15 antisera reacted with all H. influenzae isolates as determined by immunoblot analyses.
(v) Purification of a Full-length Recombinant D15 Protein Expressed in E. coli.
A full-length recombinant D15 (rD15) protein was expressed in inclusion bodies in E. coli . As shown in FIG. 6, purification of rD15 inclusion bodies was achieved by a sequential extraction of the E. coli cell lysate with 50 mM Tris-HCl1, pH 8.0, then 50 mM Tris containing 0.5% Triton X-100 and 10 mM EDTA, pH 8.0. After centrifugation, more than 95% of the proteins in the resulting pellet was an 80 kDa protein by SDS-PAGE analysis, that reacted with a D15-specific monoclonal antibody on an immunoblot. The N-terminal sequence of the rD15 was found to be Met-Ala-Pro-Phe-Val-Lys-Asp-(SEQ ID NO: 54) which is identical to the predicted amino acid sequence.
The rD15 inclusion bodies were solubilized with a mixture of PBS, 0.5% Triton X-100, 10 mM EDTA and 8 M urea (see Example 8). After dialysis against PBS to remove urea, more than 80% of the D15 protein remained soluble. This soluble rD15 antigen was used for the immunogenicity studies described below. From shake-flask experiments, it was estimated that about 10 mg of soluble rD15 protein was obtained from 1 L of E. coli bacterial culture. It is clear that growing the recombinant E. coli strains under optimised fermentation conditions significantly increase the level of rD15 production.
(vi) Immunogenicity of the Full-length Recombinant D15 Protein (rD15)
The immunogenicity of the full-length rD15 protein was studied in guinea pigs and mice. Using the immunization protocols described in FIG. 7, a 15 μg dose of rD15 induced high IgG titers in guinea pigs when administered in the presence of either Preund's adjuvant or AlPO 4 . In the mouse dose-response study, the protein appeared to be immunogenic at a dose as low as 5 μg in either Freund's adjuvant (FIG. 8A) or AlPO 4 (FIG. 8 B).
The protective ability of rD15 against H. influenzae type b infection was examined in the infant rat model of bacteremia essentially as described by Loeb (1987). Thus, infant rats passively immunized with guinea pig anti-rD15 antisera were significantly less bacteremic than controls injected with pre-bleed sera, which is consistent with the previous report by Thomas et al. (1990).
(vii) Purification and Characterization of the N-terminal rD15 Fragment.
The truncated rD15 fragment corresponding to the N-terminus of the D15 protein (residues 22 to 223) as described in Example 6, was expressed in E. coli as a soluble protein fused to GST. The fusion protein (46 kDa) was readily extracted using phosphate buffered saline (PBS). Purification of the GST-D15 fragment fusion protein was achieved by a single-step affinity purification process on a glutathione-Sepharose 4B column (FIG. 9, Lane 3). Cleavage of the 46 kDa fusion protein with thrombin yielded two fragments (FIG. 9, Lane 4), a 26 kDa protein which corresponded to a purified GST standard (FIG. 9, Lane 2), and a 20 kDa polypeptide which had the size expected for the N-terminal rD15 fragment (amino acid residues 63 to 223), respectively. Separation of these two proteins was achieved by a second round of glutathione-Sepharose 4B affinity chromatography. From shake-flask experiments, it was estimated that about 1 mg of purified N-terminal rD15 fragment was recovered from 1 L of E. coli bacterial culture. It is clear that growing the recombinant E. coli strains under optimised fermentation conditions will significantly increase the level of N-terminal rD15 fragment production.
The identity of the 20 kDa polypeptide and the 26 kDa protein was confirmed by both immunoblotting and protein sequencing. The N-terminal sequence of the 20 kDa polypeptide was found to be NH 2 -Ser-Leu-Phe-Val-Ser-Gly-Arg-Phe-Asp-Asp-Val-Lys-Ala-His-Gln-Glu-Gly-Asp-Val-Leu-Val-Val-Ser-(SEQ ID NO: 12), which corresponds to residues 63 to 85 of the primary sequence of D15. This result indicates that there is a spurious thrombin cleavage site within the D15 sequence and that the first 42 amino acids of the rD15 fragment are cleaved off during thrombin digestion. Thus, the final N-terminal rD15 fragment was 161 amino acids in length corresponding to residues 63 to 223 of the primary sequence of D15. The N-terminal sequence obtained for the 26 kDa protein (NH2-Met-Ser-Pro-Ile-Leu-Gly-Tyr-Trp-Lys-—SEQ ID NO: 13) confirmed that it was GST.
(viii) Imogenicity of the N-terminal rD15 Fragment.
The immunogenicity of the N-terminal rD15 fragment was tested in guinea pigs using various adjuvants. Using the immunization protocols described in FIG. 10, a 10 μg dose of N-terminal rD15 fragment induced a good booster response in guinea pigs with almost all the adjuvants tested. The highest anti-D15 IgG titer was observed in the group of guinea pigs immunized with N-terminal rD15 fragment in Freund's adjuvant. The second best adjuvant was Titermax (CytRx Inc.). The other two adjuvants, TPAD4 (tripalmityl-Cys-Ser-Glu 4 ) and AlPO 4 were equally potent.
(ix) Protective Ability of the N-terminal rD15 Fragment Against H. influenzae Type b Challenge.
An in vivo challenge model for a assessing the protective abilities of antigen against diseases caused by Haemophilus is the infant rat model of bacteremia as described by Loeb 1987. The protective ability of the N-terminal rD15 fragment against H. influenzae type b challenge was examined in this rat model. As illustrated in Table 1, infant rats passively immunized with rabbit anti-N-terminal rD15 fragment antisera showed significantly lower bacteremia compared to those injected with pre-bleed sera.
Since passively transferred antisera against the N-terminal rD15 fragment were found to be protective in the infant rat model of bacteremia, it was of interest to identify the protective epitope(s) of this N-terminal rD15 fragment. The first nine overlapping peptides of the D15 protein as listed in Table 2 were chemically synthesized based upon the amino acid sequence derived from the sequence of the D15 gene from H. influenzae type b Ca (FIG. 1 ). These synthetic peptides were assessed for their reactivities with either rabbit or guinea pig antisera raised against purified N-terminal rD15 fragment by ELISAs. As shown in Table 3, both guinea pig and rabbit antisera reacted with a cluster of D15 peptides, including peptides D15-P4 to D15-P8 encompassing residues 93 to 209 of the D15 primary sequence.
Further studies were performed to determine whether the protection against H. influenzae type b observed using rabbit anti-D15 antisera in infant rats could be neutralized by D15 peptides. In the first experiment, a rabbit anti-N-terminal rD15 fragment antiserum was injected into a group of seven infant rats in the presence or absence of a mixture of the nine D15 peptides (D15-P2 to D15-P10). Animals in the positive control group were injected with the rabbit anti-N-terminal rD15 fragment antiserum mixed with purified D15 fragment and the negative control group was injected with a mixture of the nine peptides only. As illustrated in Table 4, infant rats passively immunized with a rabbit anti-N-terminal rD15 fragment antiserum (group #1) showed a significantly lower bacteremia level (3%, p−1.2×10 −7 ) compared to those in the negative control group (group #4, 100%), which was consistent with the previously obtained results. The protection mediated by the rabbit anti-N-terminal rD15 fragment antiserum was largely neutralized by the addition of purified N-terminal rD15 fragment (group #3, 64%), as indicated by the lack of significant difference in the bacteremia level between group #3 and group #4 (p=0.09). Although the addition of the mixture of nine D15 peptides only slightly neutralized the protection conferred by the antiserum (group #2, 13%) as compared to group #1 (3%), the difference in bacteria counts between these two groups was statistically significant (p=0.0037).
To more clearly define the protective epitope(s) of the N-terminal rD15 fragment, the above experiment was repeated with a mixture of five peptides (peptides D15-P4 to D15-P8) which were chosen for their strong reactivities with the rabbit anti-N-terminal rD15 fragment antiserum. The results obtained from this second experiment showed that the protection observed using rabbit anti-N-terminal rD15 fragment (Table 5, group #1) was completely blocked by the addition of this mixture of five peptides (Table 5, group #2, 106%, p=0. 53×10 −8 ) These results strongly indicate that a cocktail of D15 synthetic peptides may be used as immunogens to induce protective antibodies against H. influenzae.
(x) Epitope Prediction and Peptide Snythesis.
To map the immunodominant T-cell or B-cell epitopes of D15, overlapping synthetic peptides covering the entire D15 protein sequence (Table 2 —SEQ ID NO: 14 to 49) were synthesized using the t-Boc solid-phaae peptide synthesis as described in Example 15. The peptides were chosen based on their high index of hydrophillic β-turns estimated by secondary structure prediction analysis (FIG. 11 ). Such peptides are likely to be surface-exposed and antigenic. Peptides more than 25 residues in length were selected to better mimic native epitopes.
(xi) Identification and Characterization of Immunodominant Epitopes of D15 using Synthetic Peptide.
To map the linear B-cell epitopes of D15, overlapping synthetic peptides representing the entire sequence of D15 were individually coated onto ELISA plates and probed with several anti-rD15 antisera as described in Example 19. The results are summarized in Table 6. Mouse antisera raised against rD15 reacted with all D15 peptides, but the major epitopes were located within peptides D15-P8 (residues 180-209—SEQ ID NO: 21), D15-P10 (residues 219-249—SEQ ID NO: 23), D15-P11 (residues 241-270—SEQ ID NO: 24), and D15-P26 (residues 554-582—SEQ ID NO: 39), respectively. Rabbit anti-D15 antisera recognized only peptides D15-P4 (residues 93-122—SEQ ID NO: 17), D15-P14 (residues 304-333—SEQ ID NO: 27) and D15-P36 (residues 769-798—SEQ ID NO: 49). Guinea pig antisera raised against rD15 reacted with peptides D15-P2 (residues 45-72—SEQ ID NO: 15), D15-P4 (residues 93-122—SEQ ID NO: 17), D1S-P6 (residues 135-164—SEQ ID NO: 19), D15-P8 (residues 180-209—SEQ ID NO: 21), D15-P14 (residues 304-333—SEQ ID NO: 27), D15-P27 (residues 577-602—SEQ ID NO: 40). The immunodominant linear B-cell epitopes of D15 were thus found to be located within peptides D15-P4 (residues 93-122—SEQ ID NO: 17) and D15-P14 (residues 304-333—SEQ ID NO: 27), since these are the only two peptides recognized by rD15-specific antisera from all three animal species. These results indicate that the peptides containing the linear B-cell epitope sequences described above can be used as target antigens in, for example, diagnostic kits to detect the presence of anti-D15 and anti- H. influenzae antibodies in samples.
(xii) Identification and Characterization of Immunodominant T-cell Epitopes of D15 using Synthetic Peptides.
The importance of cytokine networks in the immune and inflammatory responses in immunity and inflammation and their alteration in pathology is becoming more evident as new members of the cytokine family are identified and characterized. Mills et al. (1993) have recently reported that there is a rapid clearance of B. pertussis from the lungs of mice on challenge six weeks after respiratory infection or following two immunizations with the whole-cell pertussis vaccine. Spleen cells from these immunized mice were found to secrete high levels of IL-2 and IFN-γ and low levels of IL-5 in the presence of pertussis antigen (pertussis toxoid, filamentous haemagglutinin (FHA) and pertactin). This result suggests that Th1 cell (T-cells producing high levels of IL-2 and IFN-γ) proliferation is very important for recovering from respiratory infection. The generation of Th1 and Th2 cell subsets is regulated by the balance between different groups of cytokines, predominantly IL-12 and IL-4 (Trinchieri, 1993). IL-12 and IL-4 are responsible for Th1 and Th2 cells differentiation, respectively. One of the roles of Th2 cells in the immune system is to provide helper activity for eliciting high levels of antigen-specific antibodies following immunization. Antigens containing Th1epitope(s) stimulate antigen-specific T-cells to produce high levels of IL-2 and IFN-γ, whereas Th2 epitope(s) induce high levels of IL-4 expression. Th0 epitope(s) stimulate the synthesis of IFN-γ and IL-4.
Little is known about the cellular immune response to outer membrane proteins of H. influenzae and its role in the protection against H. influenzae infection and diseases. To this end, the inventors performed studies of the cellular response elicited in mice following rD15 immunization. D15-specific T-cell epitopes were determined using D15 peptides and T-cell lines obtained from five BALB/c mice immunized with rD15 (see Example 23). The lymphocyte proliferative responses of the D15-specific T-cell lines to overlapping D15 peptides were determined in conventional cytokine assays as described in Example 24. The results summarized in Table 7, revealed that stimulation only with certain synthetic peptides elicited proliferative responses and the release of specific cytokines. Synthetic peptides corresponding to residues 114-143 (D15-P5—SEQ ID NO: 18), 282-312 (D15-P13—SEQ ID NO: 26) and 577-602 (D15-P27—SEQ ID NO: 40), and 219-249 (D15-P10—SEQ ID NO: 23), 262-291 (D15-P12—SEQ ID NO: 25), 390-416 (D15-P18—SEQ ID NO: 31), 410-435 (D15-P19—SEQ ID NO: 32) 554-582 (D15-P26—SEQ ID NO: 39), 596-625 (D15-P28—SEQ ID NO: 41), 725-750 (D15-P34—SEQ ID NO: 47) and 745-771 (D15-P35—SEQ ID NO: 48) were shown to be highly stimulatory for rD15-specific BALB/c Th0 cells and Th1 cells, respectively. Therefore, these immunodominant T-cell epitopes can be used as autologous carriers for PRP, and/or OMP B-cell epitopes to enhance their immunogenicity. The Th1 cell epitopes identified above may be useful in the H. influenzae vaccine formulations to induce H. influenzae -specific cellular immune responses.
(xiii) Immunogenicity of D15 Peptides.
To determine whether synthetic D15 peptides were immunogenic free peptides were assessed individually for their immunogenicity. Rabbit and guinea pig anti-peptide antisera were tested for their reactivities with the immunizing peptides as well as with native D15 and rD15 by ELISA and immunoblotting. As shown in Table 8, all guinea pig anti-D15 peptide antisera except those raised against D15-P26 (SEQ ID NO: 39), D15-P29 (SEQ ID NO: 42), D15-P30 (SEQ ID NO: 43) and D15-P31 (SEQ ID NO: 44) were shown to be immunogenic by ELISAs. The induction of high titers of peptide-specific IgG antibodies by free peptides clearly indicates that most peptides contain both a functional T-helper determinant and a B-cell epitope(s). In addition, these anti-peptide antisera recognized D15 in the immunoblot assay. Since most peptides contain potent functional T-helper determinant(s) and induce strong IgG antibody responses in mammals, they are candidate immunogens for inclusion in an H. influenzae vaccine preparation. D15 peptide-specific antisera cross-reacted with D15 from non-typeable strains of H. influenzae as judged by immunoblotting. This finding indicates that immunogenic D15 peptides contain epitopes which are highly conserved among typeable and non-typeable strains of H. influenzae . In addition, polyclonal antibodies against these epitopes are useful to detect H. influenzae in biological samples.
Therefore, these conserved epitopes of D15 can be used either individually or in combination to prepare cross-reactive synthetic immunogens against typeable and non-typeable strains of H. influenzae and other bacteria that produce D15 protein, a fragment or an analog thereof. Peptides described above can be further polymerized, or modified with lipids as lipopeptides, or linked to polysaccharides including PRP as synthetic glycopeptide or lipoglycopeptide conjugates to produce alternate vaccines. These vaccines can be used to immunize against diseases caused by H. influenzae when administered to mammals, for example, by the intramuscular or parenteral route, or when delivered using microparticles, capsules, liposomes and targeting molecules, such as toxins or fragments thereof, and antibodies, to cells of the immune system or mucosal surfaces.
(xiv) Utility of D15 as Carrier Protein for the Production of Glycoconjugates.
To determine whether D15 may serve both as a protective antigen and a carrier, D15-PRP conjugation experiments were performed as described in Example 14. The D15-PRP conjugates were found to be highly immunogenic in rabbits and able to elicit both anti-D15 and anti-PRP IgG antibody responses as judged by D15-specific ELISA and PRP-BSA immunoassay (Table 9). These results clearly demonstrate the practical utility of D15 as a carrier protein for glycoconjugation technology.
In preferred embodiments of the present invention, the carrier function of D15 can be generally utilized to prepare chimeric molecules and conjugate vaccines against pathogenic bacteria, including encapsulated bacteria. Thus, the glycoconjugates of the present inventions may be applied to vaccinations to confer protection against infection with any bacteria having polysaccharide antigens, including, for example, Haemophilus influenzae, Streptococcus pneumoniae, Escherichia coli, Neisseria meningitidis, Salmonella typhi, Streptococcus mutans, Cryptococcus neoformans , Klebsiella, Staphylococcus aureus and Pseudomonas aeruginosa.
In another embodiment, the carrier function of D15 may be used, for example, to induce immunity toward abnormal polysaccharides of tumor cells, or to produce anti-tumor antibodies that can be conjugated to chemotherapeutic or bioactive agents.
Accordingly, the present invention provides the primary sequence and the preparation of an antigen (D15) of H. influenzae that can be used in the prevention and diagnosis of diseases caused by Haemophilus. In particular, the inventors discovered that recombinant D15 or its fragments, can elicit protective antibody responses against live H. influenzae type b bacteria challenge. Thus, the present inventions have utility in vaccines. The invention also discloses the nucleotide sequences of the D15 genes isolated from both H. influenzae type b strains and non-typeable isolates. The DNA segments encoding D15 are disclosed and show minor polymorphism in both their nucleotide and derived amino acid sequences (FIGS. 1 F and 3 ). These DNA segments may be used to provide an immunogen essentially free from other H. influenzae antigens (such as PRP and lipooligosaccharides (LOS)) through the application of recombinant DNA technology. The present disclosure further provides novel techniques which can be employed for preparing essentially pure D15 or fragments thereof, as well as functional analogs. The recombinant D15 protein, fragment or analog thereof, may be produced in a suitable expression system, such as E. coli, Haemophilus Bordetella , Bacillus, Fungi, Yeast, Baculovirus, Poxvirus, vaccinia or mammalian expression systems.
In one embodiment, the present invention concerns the process of preparing vaccine compositions which include purified recombinant D15 protein (rD15) or rD15 fragments that are immunologically cross-reactive with native D15. In particular, the gene coding the entire D15 protein and a DNA segment encoding an N-terminal rD15 fragment fused to the glutathione-S-transf erase gene have been constructed and expressed in E. coli . The expressed rD15 protein and its fragments were found to cross-react immunologically with the native D15 antigen isolated from both typeable and non-typeable H. influenzae isolates and thus represent cross-reactive immunogens for inclusion in a vaccine against diseases caused by H. influenzae . Furthermore, Haemophilus convalescent serum recognized D15 purified from H. influenzae as described herein, rD15 and N-terminal rD15 fragment.
In another embodiment, the present invention provides a gene coding for the outer membrane protein D15 from H. influenzae having the specific nucleotide sequences described herein or ones substantially homologous thereto (i.e. those which hybridize under stringent conditions to such sequences), for genetically engineering hybrids or chimeric proteins containing a D15 fragment fused to another polypeptide or protein or a polysaccharide, such as H. influenzae outer membrane proteins, for example, P1, P2, or P6 or PRP. As a result, the hybrids, chimeric proteins or glycoconjugates may have higher protectivity against H. influenzae than D15, or P1, or P2, or P6, or PRP alone.
Thus, D15 outer membrane protein can function both as a protective antigen and as a carrier in a conjugate vaccine to provide autologous T-cell priming, wherein the hapten part of the conjugate is the capsular polysaccharide moiety (PRP) of H. influenza . This D15-carbohydrate conjugate can elicit antibodies against both PRP and D15, and thus should enhance the level of protection against H. influenzae -related diseases, especially in infants.
In another embodiment, the present invention comprises an essentially pure form of at least one protein or peptide containing an amino acid sequence corresponding to at least one antigenic determinant of D15, which peptide is capable of eliciting polyclonal antibodies against H. influenzae in mammals. These D15-specific antibodies are useful in test kits for detecting the presence of H. influenzae in biological samples. The peptides can have, for example, the amino acid sequences corresponding to residues 20-49, 45-74, 68-99, 93-122, 114-143, 135-164, 157-187, 180-209, 199-228, 219-249, 241-270, 262-291, 282-312, 304-333, 325-354, 346-375, 367-396, 390-416, 410-435, 430-455, 450-477, 471-497, 491-516, 511-538, 532-559, 554-582, 577-602, 596-625, 619-646, 641-666, 662-688, 681-709, 705-731, 725-750, 745-771, 769-798 (SEQ ID NOS: 14 to 49) of the D15 protein of the H. influenzae type b Ca strain, respectively, as set forth in Table 2 below, or any portion, variant or mutant thereof which retains immunogenicity.
In yet another embodiment, the present invention provides pure native D15 protein, extracted and chromatographically purified from cultures of H. influenzae typeable or non-typeable isolates. The novel procedures involves extraction of the D15 protein from cell paste by techniques known for other outer membrane proteins, with an aqueous detergent solution, followed by purification by centrifugation and chromatography. The purified native D15 antigen can be used to immunize mammals against diseases caused by H. influenzae , for example, by the intramuscular or the parenteral routes, or by delivering it using microparticles, capsules, liposomes and targeting molecules, such as toxins or fragments thereof, and antibodies.
Another aspect of the present invention is that the D15 outer membrane protein, fragments or analogs thereof or peptides corresponding to portions of D15 may be components of a multivalent vaccine against otitis media. This multivalent vaccine comprises at least one immunogenic determinant of D15 as described herein, along with at least one protective antigen isolated from Strentococcus lneumoniae, Branhamella ( Moroxella ) catarrhalis, Stalphlococcus aureus , or respiratory syncytial virus, in the presence or absence of adjuvant.
The D15 peptides (Table 2) or any portion, variant or mutant thereof, can easily be synthesized either manually or with a commercially available peptide synthesizer, such as the Applied Biosystems Model 430A synthesizer.
It is clearly apparent to one skilled in the art, that the various embodiments of the present invention have many applications in the fields of vaccination, diagnosis, and treatment of diseases caused by Haemophilus infections, and the generation of immunological reagents. A further non-limiting discussion of such uses is further presented below.
1. Vaccine Preparation and Use
Immunogenic compositions, suitable for use as vaccines, may be prepared from immunogenic D15 outer membrane protein, fragments or analogs thereof and/or peptides corresponding to portions of D15 as disclosed herein. The vaccine elicits an immune response which produces antibodies, including anti-D15 outer membrane protein antibodies and antibodies against D15 that are opsonizing or bactericidal. Should the vaccinated subject be challenged by Haemophilus, the antibodies bind to the D15 outer membrane protein and thereby inactivate the bacterium. Opsonizing and bactericidal antibodies represent examples of antibodies useful in protection against disease.
Vaccines containing peptides are generally well known in the art, as exemplified by U.S. Pat. Nos. 4,601,903; 4,599,231; 4,599,230; and 4,596,792; all of which references are incorporated herein by reference. As to any further reference to patents and references in this description, they are as well hereby incorporated by reference without any further notice to that effect. Vaccines may be prepared as injectables, as liquid solutions or emulsions. The D15 outer membrane protein, fragments or analogs thereof or peptides corresponding to portions of D15 may be mixed with physiologically-acceptable excipients which are compatible with the D15 outer membrane protein, fragments, analogs or peptides. Excipients may include, water, saline, dextrose, glycerol, ethanol, and combinations thereof. The vaccine may further contain minor amounts of auxiliary substances such as wetting or emulsifying agents, pH buffering agents, or adjuvants to enhance the effectiveness of the vaccines. Methods of achieving adjuvant effect for the vaccine includes use of agents, such as aluminum hydroxide or phosphate (alum), commonly used as 0.05 to 0.1 percent solution in phosphate buffered saline. Vaccines may be administered parenterally, by injection subcutaneously or intramuscularly. Alternatively, other modes of administration including suppositories and oral formulations may be desirable. For suppositories, binders and carriers may include, for example, polyalkalene glycols or triglycerides. Oral formulations may include normally employed incipients such as, for example, pharmaceutical grades of saccharine, cellulose, magnesium carbonate and the like. These compositions take the form of solutions, suspensions, tablets, pills, capsules, sustained release formulations or powders and contain 10-95% of the D15 outer membrane protein, fragment analogs and/or peptides.
The vaccines are administered in a manner compatible with the dosage formulation, and in an amount which is therapeutically effective, protective and immunogenic. The quantity to be administered depends on the subject to be treated, including, for example, the capacity of the individual's immune system to synthesize antibodies, and if needed, to produce a cell-mediated immune response. Precise amounts of active ingredient required to be administered depend on the judgment of the practitioner. However, suitable dosage ranges are readily determinable by one skilled in the art and may be of the order of micrograms of the D15 outer membrane protein, analog, fragment and/or peptides. Suitable regimes for initial administration and booster doses are also variable, but may include an initial administration followed by subsequent administrations. The dosage of the vaccine may also depend on the route of administration and varies according to the size of the host.
The nucleic acid molecules encoding the D15 outer membrane protein of the present invention may also be used directly for immunization by administration of the DNA directly, for example, by injection for genetic immunization or by constructing a live vector, such as Salmonella, BCG, adenovirus, poxvirus or vaccinia. A discussion of some live vectors that have been used to carry heterologous antigens to the immune system are discussed in, for example, O'Hagan (1992). Processes for the direct injection of DNA into test subjects for genetic immunization are described in, for example, Ulman et al. (1993).
The use of peptides in vivo may first require their chemical modification since the peptides themselves may not have a sufficiently long serum and/or tissue half-life. Such chemically modified peptides are referred to herein as peptide analogs. The term peptide analog extends to any functional chemical equivalent of a peptide characterized by its increased stability and/or efficacy in vivo or in vitro in respect of the practice of the invention. The term peptide analog is also used herein to extend to any amino acid derivative of the peptides as described herein. Peptide analogs contemplated herein are produced by procedures that include, but are not limited to, modifications to side chains, incorporation of unnatural amino acids and/or their derivatives during peptide synthesis and the use of cross-linkers and other methods which impose conformational constraint on the peptides or their analogs.
Examples of side chain modifications contemplated by the present invention include modification of amino groups, such as by reductive alkylation by reaction with an aldehyde followed by reduction with NaBH 4 ; amidation with methylacetimidate; acetylation with acetic anhydride; carbamylation of amino groups with cyanate; trinitrobenzylation of amino groups with 2, 4, 6, trinitrobenzene sulfonic acid (TNBS); alkylation of amino groups with succinic anhydride and tetrahydrophthalic anhydride; and pyridoxylation of lysine with pyridoxa-5′-phosphate followed by reduction with NaBH 4 .
The guanidino group of arginine residues may be modified by the formation of heterocyclic condensation products with reagents such as 2,3-butanedione, phenylglyoxal and glyoxal.
The carboxyl group may be modified by carbodiimide activation via o-acylisourea formation followed by subsequent derivatisation, for example, to a corresponding amide.
Sulfhydryl groups may be modified by methods, such as carboxymethylation with iodoacetic acid or iodoacetamide; performic acid oxidation to cysteic acid; formation of mixed disulphides with other thiol compounds; reaction with maleimide; maleic anhydride or other substituted maleimide; formation of mercurial derivatives using 4-chloromercuribenzoate, 4-chloromercuriphenylsulfonic acid, phenylmercury chloride, 2-chloromercuric-4-nitrophenol and other mercurials; carbamylation with cyanate at alkaline pH.
Tryptophan residues may be modified by, for example, oxidation with N-bromosuccinimide or alkylation of the indole ring with 2-hydroxy-5-nitrobenzyl bromide or sulphonyl halides. Tryosine residues may be altered by nitration with tetranitromethane to form a 3-nitrotyrosine derivative.
Modification of the imidazole ring of a histidine residue may be accomplished by alkylation with iodoacetic acid derivatives or N-carbethoxylation with diethylpyrocarbonate.
Examples of incorporating unnatural amino acids and derivatives during peptide synthesis include, but are not limited to, use of norleucine, 4-amino butyric acid, 4-amino-3-hydroxy-5-phenylpentanoic acid, 6-aminohexanoic acid, t-butylglycine, norvaline, phenylglycine, ornithine, sarcosine, 4-amino-3-hydroxy-6-methylheptanoic acid, 2-thienyl alanine and/or D-isomers of amino acids.
2. Immunoassays
The D15 outer membrane protein, analog, fragment and/or peptides of the present invention are useful as antigens in immunoassays, including enzyme-linked immunosorbent assays (ELISA), RIAs and other non-enzyme linked antibody binding assays or procedures known to the art for the detection of anti-bacterial, Haemophius D15 and/or peptide antibodies. In ELISA assays, the D15 outer membrane protein, fragment or analogs thereof and/or peptides corresponding to portions of D15 outer membrane protein are immobilized onto a selected surface, for example, a surface exhibiting a protein affinity, such as the wells of a polystyrene microtiter plate. After washing to remove incompletely adsorbed D15 outer membrane protein, analog, fragment and/or peptides, a nonspecific protein, such as bovine serum albumin (BSA) or casein, that is known to be antigenically neutral with regard to the test sample may be bound to the selected surface. This allows for blocking of nonspecific adsorption sites on the immobilizing surface and thus decreases the background caused by nonspecific bindings of antisera onto the surface. Normally, the peptides employed herein are in the range of 12 residues and up and preferably 14 to 30 residues.
The immobilizing surface is then contacted with a sample such as clinical or biological materials to be tested in a manner conducive to immune complex (antigen/antibody) formation. This may include diluting the sample with diluents, such as BSA, bovine gamma globulin (BGG) and/or phosphate buffered saline (PBS)/Tween. The sample is then allowed to incubate for from 2 to 4 hours, at temperatures, such as of the order of 25° to 37° C. Following incubation, the sample-contacted surface is washed to remove non-immunocomplexed material. The washing procedure may include washing with a solution such as PBS/Tween, or a borate buffer.
Following formation of specific immunocomplexes between the test sample and the bound D15 outer membrane protein, analog, fragment and/or peptides, and subsequent washing, the occurrence, and even amount, of immunocomplex formation may be determined by subjecting the immunocomplex to a second antibody having specificity for the first antibody. If the test sample is of human origin, the second antibody is an antibody having specificity for human immunoglobulins and, in general, IgG. To provide detecting means, the second antibody may have an associated activity, such as an enzymatic activity that will generate, for example, a color development upon incubating with an appropriate chromogenic substrate. Quantification may then achieved by measuring the degree of color generation using, for example, a visible spectra spectrophotometer.
3. Use of Sequnces as Hybridization Probes
The nucleotide sequences of the present invention comprising the sequence of the D15 outer membrane protein, now allow for the identification and cloning of the D15 outer membrane protein genes from any species of Haemophilus and other bacteria that have genes encoding D15 outer membrane proteins.
The nucleotide sequences comprising the sequence encoding the D15 outer membrane protein of the present invention are useful for their ability to selectively form duplex molecules with complementary stretches of other D15 genes. Depending on the application, a variety of hybridization conditions may be employed to achieve varying degrees of selectivity of the probe toward the other D15 genes. For a high degree of selectivity, stringent conditions are used to form the duplexes, such as low salt and/or high temperature conditions, such as provided by 0.02 M to 0. 15 M NaCl at temperatures of between about 50° C. to 70° C. For some applications, less stringent hybridization conditions are required such as 0.15 M to 0.9 M salt, at temperatures ranging from between about 20° C. to 55° C. Hybridization conditions can also be rendered more stringent by the addition of increasing amounts of formamide, to destabilize the hybrid duplex. Thus, particular hybridization conditions can be readily manipulated, and will generally be a method of choice depending on the desired results.
In a clinical diagnostic embodiment, the nucleic acid sequences of the D15 outer membrane protein genes of the present invention may be used in combination with an appropriate means, such as a label, for determining hybridization. A wide variety of appropriate indicator means are known in the art, including radioactive, enzymatic or other ligands, such as avidin/biotin, which are capable of providing a detectable signal. In some diagnostic embodiments, an enzyme tag, such as urease, alkaline phosphatase or peroxidase, instead of a radioactive tag may be used. In the case of enzyme tags, calorimetric indicator substrates are known which can be employed to provide means visible to the human eye or spectrophotometrically, to identify specific hybridization with samples containing D15 gene sequences.
The nucleic acid sequences of D15 genes of the present invention are useful as hybridization probes in solution hybridizations and in embodiments employing solid-phase procedures. In embodiments involving solid phase procedures, the test DNA (or RNA) from samples, such as clinical samples, including exudates, body fluids (e. g., serum, amniotic fluid, middle ear effusion, sputum, bronchoalveolar lavage fluid) or even tissues, is adsorbed or otherwise affixed to a selected matrix or surface. The fixed, single-stranded nucleic acid is then subjected to specific hybridization with selected probes comprising the nucleic acid sequences of the D15 genes or fragments thereof of the present invention under desired conditions. The selected conditions will depend on the particular circumstances based on the particular criteria required depending on, for example, on the G+C contents, type of target nucleic acid, source of nucleic acid, size of hybridization probe etc. Following washing of the hybridization surface so as to remove non-specifically bound probe molecules, specific hybridization is detected, or even quantified, by means of the label. The selected probe should be at least 18 bp and may be in the range of 30 bp to 90 bp long.
4. Expression of the D15 Outer Membrane Protein Genes
Plasmid vectors containing replicon and control sequences which are derived from species compatible with the host cell may be used for the expression of the D15 outer membrane protein genes in expression systems. The vector ordinarily carries a replication site, as well as marking sequences which are capable of providing phenotypic selection in transformed cells. For example, E. coli may be transformed using pBR322 which contains genes for ampicillin and tetracycline resistance and thus provides easy means for identifying transformed cells. The pBR322 plasmid, or other microbial plasmid or phage must also contain, or be modified to contain, promoters which can be used by the microbial organism for expression of its own proteins.
In addition, phage vectors containing replicon and control sequences that are compatible with the host microorganism can be used as a transforming vector in connection with these hosts. For example, the phage in lambda GEM™-11 may be utilized in making recombinant phage vectors which can be used to transform host cells, such as E. coli LE392.
Promoters commonly used in recombinant DNA construction include the β-lactamase (penicillinase) and lactose promoter systems and other microbial promoters, such as the T7 promoter system. Details concerning the nucleotide sequences of promoters are known, enabling a skilled worker to ligate them functionally with plasmid vectors. The particular promoter used generally is a matter of choice depending upon the desired results. Hosts that are appropriate for expression of the transferrin receptor genes, fragment analogs or variants thereof include E. coli , Bacillus, Haemophilus, Bordetella, fungi, yeast, or the baculovirus and poxvirus expression systems may be used.
In accordance with an aspect of this invention, it is preferred to make the D15 outer membrane protein, fragment or analog thereof by recombinant methods, particularly since the naturally occurring D15 protein as purified from culture of a species of Haemophilus may include undesired contaminants, including trace amounts of toxic materials. This problem can be avoided by using recombinantly produced D15 outer membrane protein in heterologous systems which can be isolated from the host in a manner to minimize toxins in the purified material. Particularly desirable hosts for expression in this regard include Gram positive bacteria which do not have lipopolysaccharide (LPS) and are, therefore, endotoxin free. Such hosts include species of Bacillus and may be particularly useful for the production of non-pyrogenic D15 outer membrane protein, fragments or analogs thereof.

The above disclosure generally describes the present inversion. A more complete understanding can be obtained by reference to the following specific Examples. These Examples are described solely for purposes of illustration and are not intended to limit the scope of the invention. Although specific terms have been employed herein, such terms are intended in a descriptive sense and not for purposes of limitations. Immunological and recombinant DNA methods may not be explicitly described in this disclosure but are well within the scope of those skilled in the art.
EXAMPLES
Methods of molecular genetics, protein biochemistry, and immunology used but not explicitly described in this disclosure and these EXAMPLES are amply reported in the scientific literature and are well within the ability of those skilled in the art.
Example 1
This Example illustrates the cloning and sequencing of the D15 genes.
Genomic DNA was purified from the Haemophilus influenzae type b strain Ca by lysis of the bacteria with pronase and sodium dodecylsulphate followed by phenol extraction and isopropanol precipitation, according to Berns and Thomas, 1965. The DNA was then partially digested with EcoRI and the DNA fraction containing 6-10 kb fragments was isolated following electrophoresis in low-melting point agarose. These fragments were ligated into a lambda gtll Ampl vector (Thomas and Rossi, 1986) and cloned as a lysogen into E. coli strain BTA282. Recombinant clones were selected for their ampicillin resistance conferred by the vector. To identify clones producing H. influenzae type b antigen, the clones were replica-plated on nitrocellulose filters and duplicate colonies induced for expression by temperature switch to 42° C. for 2 hours. Colonies were lysed by wetting the filters with 1% sodium dodecylsulphate (SDS). The filters were then placed into a chloroform-saturated atmosphere for 15 min. The filters were then assayed by colony radioimmuno-assay using a hyperimmune rabbit anti- H. influenzae type b antiserum absorbed with E. coli lysate for antigen expression. Clones shown by autoradiography to be producing H. influenzae type b antigens were further purified and their replicates retested for reactivity with the hyperimmune anti- H. influenzae type b antiserum. The antiserum absorbed with 10 10 intact H. influenzae type b bacteria (strain Ca) was used as negative control.
A number of clones were identified which reacted with the unabsorbed, but not with the absorbed antiserum and were further analysed. One of the clones, D15, was purified, grown and found to produce a H. influenzae type b antigen which migrated in sodium dodecyl sulphate polyacrylamide gels with a M r of about 80 kDa. Lysates from the D15 clone were coupled to Sepharose™ 4B gel and used to affinity-purify anti-D15 antibodies. This procedure is described by Thomas et al, 1990, except that the apparent M r was initially reported to be about 103 kDa. The affinity-purified antibodies to D15 were then shown to react with an M r 80 kDa protein in an outer membrane protein preparation of H. influenzae type b (sarcosyl insoluble fraction—Carlone et al, 1986). Radioimmuno dot blots and Western blots analyses of membrane preparations from both type b and nontypeable Haemophilus influenzae strains showed that affinity-purified anti-D15 antibodies reacted with all isolates. These antibodies were found to be capable of passively protecting infant rats from bacteraemia following intraperitoneal injection of live H. influenzae type b bacteria. The specificity of the protection was confirmed by absorbing out the protective activity of anti-D15 antibodies with a lysate of E. coli expressing D15 coupled to Sepharose. The protection studies have been described in detail by Thomas et al, 1990.
DNA from the lambda gtll Ampl D15 phage was isolated and a 5.7 kb fragment was released by EcoRI digestion. This fragment was subcloned into pUC19 and the resulting plasmid transformed into E. coli HB101. Recombinant bacteria were found to produce the expected M r 80 kDa H. influenzae type b antigen when examined by Western blotting. The insert DNA was then characterised by restriction endonuclease mapping. A 2.8 kb HindIII-EcoRI fragment was subcloned into pUC19 to generate plasmid pUC19/D15, which was transformed into E. coli HB101. The recombinant bacteria expressed a M r 80 kD protein recognized by D15-specific antibodies. on Western blot analysis of E. coli lysates.
Plasmid DNA was prepared from two individual colonies of recombinant E. coli HB101 containing the pUC19/D15 plasmid using standard techniques. Oligonucleotide sequencing primers of 17-25 bases in length were synthesized on the ABI model 380B DNA Synthesizer and purified by chromatography using OPC cartridges obtained from Applied Biosystems Inc., and used in accordance with the manufactures recommendations. Samples were sequenced using the ABI model 370A DNA Sequencer and dye terminator chemistry according to manufacturers' protocols. This sequence analysis indicated that the D15 gene contains an open reading frame encoding for 789 amino acids, including a putative signal sequence (FIG. 1 ). The derived amino acid sequence was found to contain the sequence of an internal peptide obtained by thrombin digestion of native D15 that had been chemically determined. The amino acid composition of D15 derived from the D15 gene sequence was comparable (within experimental error) to that of the native protein as determined by amino acid analysis.
Example 2
This Example illustrates the preparation of chromosomal DNA from Haemophilus influenzae strains Eagan, MinnA, SB33, and PAK 12085.
H. influenzae strains were grown on Mueller-Hinton agar or in brain heart infusion broth as described by Harkness et al., 1992.
Eagan Chromosomal DNA
Bacteria from 50 mL of culture were pelleted by centrifugation at 5,000 rpm, 20 minutes, 4° C. The pellet was resuspended in 25 mL TE (10 mM Tris, 1 mM EDTA, pH 8.0) and 2×5 mL aliquots used for chromosomal DNA preparation. To each aliquot were added 0.6 mL of 10% sarkosyl and 0.15 mL of 20 mg/mL proteinase K and the samples incubated at 37° C. for 1 hour. The lysate was extracted once with Tris-saturated phenol (pH 8.0) and three times with chloroform:isoamyl alcohol (24:1). The aqueous phase was pooled for a final volume of 7 mL. Then, 0.7 mL of 3M sodium acetate (pH 5.2) and 4.3 mL of isopropanol were added to precipitate the DNA which was spooled, rinsed with 70% ethanol, dried, and resuspended in 1 mL of water.
MinnA. SB33, and PAK 12085 Chromosomal DNA
Bacteria from 50 mL of culture were pelleted by centrifugation at 5,000 rpm for 15-20 minutes, at 4° C., in a Sorvall RC-3B centrifuge. The cell pellet was resuspended in 10 mL of TE (10 mM Tris-HCl, 1 mM EDTA, pH 7.5), pronase was added to 500 μg/mL, and SDS to 1%. The sample was incubated at 37° C. for about 4 hours until a clear lysate was obtained. The lysate was extracted once with Tris-saturated phenol, once with Tris-saturated phenol/chloroform (1:1), and once with chloroform. The final aqueous phase was dialysed for 24 hours against 2×500 mL of 1M NaCl at 4° C., changing the buffer once, and for 24 hours against 2×500 mL of TE at 4° C., changing the buffer once. The final dialysate was aliquotted for subsequent use.
Example 3
This Example illustrates the preparation of Haemophilus influenzae chromosomal libraries.
H. influenzae Eagan and PAK 12085 chromosomal DNAs were digested with Sau3A I (0.5 unit/10 μg DNA) at 37° C. for 15 minutes and size-fractionated by agarose gel electrophoresis. Gel slices corresponding to DNA fragments of 15-23 kb were excised and DNA was electroeluted overnight in dialysis tubing containing 3 mL of TAE (40 mM Tris-acetate, 1 mM EDTA, pH 8.0) at 14 V. The DNA was precipitated twice and resuspended in water before overnight ligation with EMBL3 BamH I arms (Promega). The ligation mixture was packaged using the Lambda in vitro packaging kit (Amersham) according to the manufacturer's instructions and plated onto E. coli NM539 cells. The library was titrated, then amplified and stored at 4° C. under 0.3% chloroform.
MinnA chromosomal DNA (10 μg) was digested with Sau3A I (40 units) for 2, 4, and 6 minutes then size-fractionated on a 10-30% sucrose gradient in TNE (20 mM Tris-HCl, 5 mM NaCl, 1 mM EDTA, pH 8.0). Fractions containing DNA fragments>5 kb were pooled and precipitated. In a second experiment, chromosomal DNA (2.6 μg) was digested with Sau3A I (4 units) for 1, 2, and 3 minutes and size-fractionated by preparative agarose gel electrophoresis. Gel slices containing DNA fragments of 10-20 kb were excised and DNA extracted by a standard freeze/thaw technique. The size-fractionated DNA from the two experiments was pooled for ligation with BamH I arms of EMBL3 (Promega). The ligation mix was packaged using the Gigapack II packaging kit (Amersham) and plated on E. coli LE392 cells. The library was titrated, then amplified and stored at 4° C. under 0.3% chloroform.
SB33 chromosomal DNA (20 μg) was digested with Sau3A I (40 units) for 2, 4, or 6 minutes and size-fractionated on a 10-30% sucrose gradient in TNE (20 mM Tris-HCl, 5 mM NaCl, 1 mM EDTA, pH 8.0). Fractions containing fragments>5 kb were pooled. In a second experiment, SB33 Chromosomal DNA (2 μg) was digested with Sau3A I (4 units) for 2, 4, or 6 minutes and size-fractionated on a preparative agarose gel. Gel slices containing DNA fragments of 10-20 kb were excised and DNA extracted by a standard freeze/thaw technique. The size-fractionated DNA from both experiments was pooled for ligation with BamH I arms of EMBL3 (Promega). The ligation mix was packaged using the Gigapack II packaging kit and plated on LE392 cells. The library was titrated, then amplified and stored at 4° C. under 0.3% chloroform.
Example 4
This Example illustrates the screening of the DNA libraries.
The Eagan, MinnA, SB33, and PAK 12085 DNA libraries were plated onto LE392 cells on NZCYM plates using 0.7% top agarose in NZCYM as overlay. Plaque lifts onto nitrocellulose filters were performed following standard procedures, and filters were processed and hybridized with a digoxigenin-labelled D15 probe prepared according to the manufacturer's specifications (Boehringer Mannheim). The probe was the EcoR I/Hind III fragment from pUC19/D15 containing the entire Ca D15 gene (FIG. 2 ). Putative plaques were plated and submitted to a second round of screening using the same procedures. Phage DNA was prepared from 500 mL of culture using standard techniques, the insert DNA was excised by Sal I digestion, and cloned into pUC to generate clones DS-712-2-1 (Eagan), DS-691-1-5 (MinnA), JB-1042-5-1 (SB33), and JB-1042-9-4 (PAK 12085), which are shown in FIG. 2 .
The nucleotide sequences of the D15 genes from H. influenzae type b strains Eagan and MinnA the non-typeable H. influenzae strains SB33 and PAK 12085 were determined and compared with that for strain Ca, as seen in FIGS. 1 b , 1 C, 1 D, 1 E and 1 F. The derived amino acid sequence are shown in FIGS. 1B, 1 C, 1 D and 1 E and are compared with the amino acid sequence of the D15 protein of H. influenzae type b Ca (FIG. 3 ).
Exanmle 5
This Example illustrates the expression of rD15 protein in E. coli.
A 2.8 kb fragment HindIII-EcoRI was subcloned into pUC19 and this pUC19/D15 plasmid was transformed into E. coli HB101. Upon induction, the positive clones expressed an 80 kDa protein which was recognized by D15-specific antisera on Western blot analysis. A HindIII-Pst I fragment was also subcloned into pUC19 and shown to express a 67 kDa protein. According to the restriction map, this 67 kDa protein corresponded to a C-terminal truncated D15 protein. on Western blot analysis, this truncated D15 was still recognized by the D15-specific antisera.
Plasmids to express the D15 gene of the non-typeable strain SB33 in E. coli were constructed. Plasmid JB-1042-5-1 containing the SB33 D15 gene and its flanking regions, was digested with EcoRI and Hind III and the 3 kb D15 insert subcloned into pUC to give plasmid pRY-60-1 (FIG. 4 ). Appropriate oligonucleotides were synthesized to restore the native D15 sequence between the ATG codon of the expression plasmid pT7-7 and the BsrF I site within the D15 gene. These oligonucleotides had the following sequence:

ACTTAGAATCAACAAACCGAGCAAGTTTACCTGTTCGTG - SEQ ID NO: 50



TGGTTGTTTAGGCTCGTTCAAATGGACAAGCACGGCC-5′- SEQ ID NO: 51

Bsr F I
















Plasmid pRY-60-1 was digested with EcoR I and BsrF I and the DNA fragment containing most of the D15 gene was purified. pUC was digested with EcoR I and Nde I and the vector fragment purified. A multi-component ligation between the pUC and D15 fragments and the oligonucleotides generated plasmid DS-860-1-1 which contains a D15 sequence without a promoter. pT7-7 was digested with Nde I and EcoR I and the vector fragment purified. DS-860-1-1 was digested with Nde I and EcoR I and the D15 insert was purified and ligated with the T7-7 vector generating plasmid DS-880-1-2 (FIG. 4 ).
The plasmid constructions were performed using E. coli JM109 as host. For expression, plasmid DS-880-1-2 was transformed into E. coli BL21/DE3, BL21/DE3/pLysS, or JM109/DE3 cells. Transformation of the cells was performed using either calcium chloride-treated competent cells or by electroporation using a BioRad electroporator. Transformed cells were grown in YT, M9, or NZCYM media and induced with IPTG or other inducing agents.
Example 6
This Example illustrates the construction and expression of the GST-D15 fragment hybrid gene in E. coli.
A forward sense primer (primer 1) 5′-GGGGAATTCCAAAAGATGTTCGT (SEQ ID NO: 52) and a reverse antisense primer CACGAATTCCCTGCAAATC-5′ (primer 7—SEQ ID NO: 53) were used to amplify a 2.8 Kb fragment HindIII-EcoRI of the D15 gene by the polymerase chain reaction that encodes the N-terminal amino acid residues 22 to 223 of the primary sequence of D15 protein (FIG. 1 A). The nucleotide sequence of the 609bp amplified fragment was confirmed by DNA sequencing. The amplified gene segment was ligated into the pGEX-2T vector downstream from the GST gene and transformed into E. coli TG-1. Colonies expressing the H. influenzae type b antigen were screened with a rabbit anti- H. influenzae type b antiserum by colony radioimmunoassay and isolated. The glutathione-S-transferase-D15 fragment fusion protein produced by transformed E. coli was isolated by affinity purification on glutathione agarose.
Example 7
This Example describes alternative expression systems for rD15.
The D15 gene or fragments thereof are also expressed in E. coli under the control of other regulated promoters. The D15 gene or fragments thereof are expressed in the absence of the leader peptide, or in other cloning systems where toxicity of D15 expression to the host is not problematic. The gene or fragments thereof are synthesized de novo or by employing the polymerase chain reaction using suitable primers. These genes are cloned into suitable cloning vectors or bacteriophage vectors in E. coli or other suitable hosts directly when toxicity can be avoided. Expression systems are Gram-positive bacteria (such as Bacillus species), pox virus, adenovirus, baculovirus, yeast, fungi, BCG or mammalian expression systems.
Example 8
This Example illustrates the protocol for extraction and purification of rD15 from E. coli expression system.
The cell pellet from a 250 mL culture, prepared as described in Example 5, was resuspended in 40 mL of 50 mM Tris, pH 8.0, and disrupted by sonication (3×10 min, 70% duty circle). The extract was centrifuged at 20,000×g and the resulting pellet saved. The initial pellet was re-extracted with 40 mL of 50 mM Tris, 0.5% Triton X-100, 10 mM EDTA, pH 8.0. The suspension was then sonicated for 10 minutes at 70% duty circle. The extract was centrifuged at 300×g for 5 minutes. The resulting supernatant was centrifuged again at 20,000×g for 30 min and the resulting pellet was saved. The pellet was resuspended in 50 mM Tris, 0.5% Triton X-100, 10 mM EDTA, pH 8.0. The suspension was then mixed with PBS/8 M urea to a final urea concentration of 6 M. The solution was then dialyzed against PBS to remove urea. After dialysis, the solution was centrifuged at 300×g for 10 min., the supernatant was saved and stored at 4° C.
Example 9
This Example demonstrates the purification of GST-(D15 fragment) fusion protein using glutathione-Sepharose 4B affinity chromatography.
Five mg of GST-(D15 fragment) fusion protein crude extract, prepared as described in Example 6, were dissolved in 5 mL of phosphate buffer saline (PBS) containing 1% Triton X-100. The solution was then loaded onto a Glutathione-Sepharose 4B column (2 mL) equilibrated with PBS containing 1% Triton X-100. The run-through of the column was discarded. The column was washed with 20 mL of PBS and the GST-(D15 fragment) fusion protein was eluted with 50 mM Tris-HCl buffer, pH 8.0, containing 5 mM glutathione. Elution was monitored by absorbance at 280 nm. Protein-containing fractions (2 mL/fraction) were collected and pooled. The purity of the protein was assessed by SDS-PAGE (FIG. 9, lane 3). The final volume of the purified fusion protein was 6 mL.
Example 10
This Example illustrates the protocol used for thrombin digestion of proteins to release the truncated D15 molecule.
The GST-(D15 fragment) fusion protein sample from Example 9 (0.1 to 0.5 mg protein/mL) was dialyzed against 1 L of 50 mM Tris-HCl buffer (pH 8.5) 3 times with at least 2 hour intervals at 4° C. to remove protease inhibitors. After dialysis, the solution was treated with human thrombin (Sigma) at a ratio of 1 mL of solution to 25 units of thrombin. The cleavage reaction was carried out at 37° C. for 2 hr and analysed by SDS-PAGE (FIG. 9, lane 4). The reaction was stopped by placing the solution in ice.
Example 11
This Example illustrates the procedure used for N-terminal rD15 fragment purification from GST using Glutathione-Sepharose 4B affinity chromatography.
A thrombin-digested GST-(D15 fragment) sample, prepared as described in Example 10, was loaded onto a Glutathione-Sepharose 4B column (2 mL) equilibrated with PBS containing 1% Triton X-100. The run-through of the column containing the N-terminal rD15 fragment was saved. After washing the column with 20 mL of PBS, the affinity column was regenerated by removing GST using 50 mM Tris-HCl buffer, pH 8.0, containing 5 mM glutathione. The purity of rD15 fragment was analysed by SDS-PAGE (FIG. 9, lane 5). This N-terminal rD15 fragment contains amino acids 63-223 of the D15 protein as a result of cleavage at the spacious thrombin site shown in FIG. 1 A.
Example 12
This Example illustrates the protocol used for the purification of D15-specific polyclonal antibodies by affinity chromatography using GST-(D15 fragment) fusion protein.
The recombinant GST-(D15 fragment) fusion protein, prepared as described in Example 9, was conjugated to cyanogen bromide-activated Sepharose. The affinity column was then used to purify antibodies from a rabbit hyperimmune anti- H. influenzae type b antiserum. The affinity purified-antibodies were shown by immunoblotting to react with a 80 kDa component present in the lysates of E. coli transformed with pUC9/D15 and in the lysates of several typeable and nontypeable H. influenzae isolates. These results confirmed that the DNA segment encoding the D15 fragment of the fusion protein was part of the open reading frame of the D15 gene.
Similarly, antisera raised against the recombinant fusion protein (Example 9) or the purified N-terminal rD15 fragment (Example 11) reacted with the D15 protein produced by H. influenzae strains (Example 13).
Example 13
This Example describes the protocol used for the purification of native D15 from H. influenzae.
Cell paste of the non-typeable H. influenzae SB33 strain, prepared from a culture grown in brain heart infusion medium supplemented with NAD (2μg/mL) and HEMIN (2 μg/mL) at 37° C., as described in Panezutti, et al, 1993, was resuspended in 50 mM Tris-HCl, pH 8.0, containing 0.5% Triton X-100 and 10 mM EDTA (20 mL per 1 g of cell paste). The mixture was stirred at room temperature for 2 hr, then centrifuged at 20,000×g for 30 minutes. The D15 was located in the supernatant and further purified.
Purification of native D15 was achieved by affinity chromatography using a D15-specific monoclonal antibody (see Example 24). The D15 extract (25 mL) was mixed with the affinity matrix (1 mL) at room temperature for 2 hr. The mixture was packed into a column and the run-through fraction was discarded. The column was washed sequentially with the following buffers: 50 mM Tris-HCl, pH 8.0, containing 0.5% Triton X-100 and 10 mM EDTA; 1 M HEPES buffer, pH 6.8; 50 mM Tris-HCl, pH 8.0, containing 0.5% Triton X-100 and 10 mM EDTA; and 10 mM phosphate buffer, pH 8.0. D15 was then eluted from the column with 3 mL of 50 mM diethylamine, pH 12.0 and the protein solution was neutralized by 1 M HEPES, pH 6.8 ({fraction (1/10)} volume). The affinity-purified native D15 was analysed by SDS-PAGE and stored at −20° C.
Example 14
This Example describes the procedure used for the preparation of D15-PRP conjugates.
Haemophilus influenzae type b oligosaccharides (PRP) prepared by controlled acid hydrolysis were conjugated either with the purified native (Example 13) or recombinant D15 (Example 8) as well as with its fragments (Example 11) using periodate oxidation as described in U.S. Pat. No. 4356170 and further details of which are presented in Example 17. The mean molecular size of the PRP molecules used for conjugation was determined as being approximately 20,000 Daltons. The conjugation was carried out without a linker molecule but may also be carried out with a linker molecule. A PRP/D15 molar ratio of approximately 7 was used to provide an excess of PRP hapten.
The PRP/rD15 conjugate was tested according to the protocol of Example 18 for immunogenicity in rabbits and elicited both primary and secondary anti-PRP IgG and anti-D15 antibody responses (Table 9). Rabbit anti-rD15-PRP antisera also strongly reacted with both native D15 and rD15 as judged by immunoblot analysis. These data indicate that rD15 can be used as a carrier protein in a conjugate vaccine. In addition, a rD15-PRP conjugate vaccine should ensure a more consistent protection against H. influenzae type b disease, particularly in infants, as a result of the additional homotypic protection provided by antibodies directed against the D15 protein.
Example 15
This Example describes the preparation of D15 peptides.
D15 peptides (Table 2) were synthesized using an ABI 430A peptide synthesizer and optimized t-Boc chemistry as described by the manufacturer, then cleaved from the resin by hydrof luoric acid (HF). The peptides were purified by reversed-phase high performance liquid chromatography (RP-HPLC) on a Vydac C4 semi-preparative column (1×30 cm) using a 15 to 55% acetonitrile gradient in 0.1% trifluoryl acetic acid (TFA) developed over 40 minutes at a flow rate of 2 mL/min. All synthetic peptides (Table 2) used in biochemical and immunological studies were >95% pure as judged by analytical HPLC. Amino acid composition analyses of these peptides performed on a Waters Pico-Tag system were in good agreement with their theoretical compositions.
Example 16
This Example describes the protocol used for D15 peptide-specific antisera production.
Guinea pigs and rabbits were immunized with individual peptides (50 to 200 μg) emulsified with Freund's complete adjuvant and injected intramuscularly. After two booster doses with the same amount of peptide in incomplete Freund's adjuvant at +14 and +28 days, the anti-peptide antisera were collected on day +42 and tested by ELISAs and immunoblotting. Both rabbit and guinea pig antisera were shown to be monospecific for their respective immunizing peptides by the peptide-specific ELISAs (Table 6). In addition, both guinea pig and rabbit antisera raised against D15 peptides reacted with both H. influenzae type b and non-typeable D15 on immunoblot analyses. Since most D15 peptides induced strong anti-peptide antibody responses in at least one animal species, they are appropriate immunogens to be included in immunogenic compositions including vaccine preparations.
Example 17
This Example describes the procedure used for the preparation of PRP-BSA conjugates.
0.5 mL of periodate-oxidized PRP (25 mg in 1 mL of 0.1 M sodium phosphate buffer, pH 6.0), prepared from native PRP treated with aqueous periodic acid (Carlone et al, 1986), was added to bovine serum albumin (BSA) (1.32 mg ; 0.02 μl) in 0.5 mL of 0.2 M sodium phosphate buffer, pH 8.0, followed by the addition of sodium cyanoborohydride (14 μg ; 0.22μmol ; 10 eqv. to BSA). After incubation at 37° C. for 5 days, the reaction mixture was dialysed against 4 L of 0.1 M phosphate buffer, pH 7.5. The resulting solution was applied onto an analytical Superose 12 column (15×300 mm, Pharmacia) equilibrated with 0.2 M sodium phosphate buffer, pH 7.2, and eluted with the same buffer. Fractions were monitored for absorbance at 230 nm. The first major protein peak was pooled and concentrated in a Centriprep 30 to 2.2 mL. The amount of protein was determined using the Bio Rad protein assay, and was found to be 300 μg/mL. The presence of PRP in the protein conjugate fraction was confirmed by the Orcinol test.
Example 18
This Example describes the protocol used for the production of anti-PRP antisera in animals using rD15 conjugates.
Rabbits were immunized intramuscularly with rD15-PRP conjugates (Example 14) (5 to 50 μg PRP equivalent) mixed with 3 mg AlPO 4 per mL, followed by two booster doses (half amount of the same immunogen) at 2 week intervals. Antisera were collected every 2 weeks after the first injection, heat-inactivated at 56° C. for 30 minutes and stored at −20° C.
Example 19
This Example illustrates the reactivity between D15 peptides and anti-peptide and D15-specific antisera using D15-specific and peptide-specific ELISAS.
Microtiter wells (Nunc-Immunoplate, Nunc, Denmark) were coated with 200 ng of purified rD15 or 500 ng of individual peptides in 50 μL of coating buffer (15 mM Na 2 CO 3 , 35 mM NaHCO 3 , pH 9.6) for 16 hours at room temperature. The plates were then blocked with 0.1% (w/v) BSA in phosphate buffer saline (PBS) for 30 minutes at room temperature. Serially diluted antisera were added to the wells and incubated for 1 hour at room temperature. After removal of the antisera, the plates were washed five times with PBS containing 0.1% (w/v) Tween-20 and 0.1% (w/v) BSA. F(ab′) 2 fragments from goat anti-rabbit, guinea pig, mouse, or human IgG antibodies conjugated to horseradish peroxidase (Jackson ImmunoResearch Labs Inc., PA) were diluted (1/8,000) with washing buffer, and added onto the microtiter plates. After 1 hr incubation at room temperature, the plates were washed five times with the washing buffer. The plates were then developed using the substrate tetramethylbenzidine (TMB) in H 2 O 2 (ADI, Toronto). The reaction was stopped with 1N H 2 SO 4 and the optical density was measured at 450 nm using a Titretek Multiskan II (Flow Labs., Virginia). Two irrelevant peptides as negative controls in the peptide-specific ELISAs. Assays were performed in triplicate, and the reactive titer of each antiserum was defined as the dilution consistently showing 2-fold increase absorbance value over those obtained from the negative controls. The results obtained are summarized in Tables 3, 6 and 8 and in the DETAILED DESCRIPTION OF THE INVENTION above.

Microtiter wells (Nunc-Immunoplate, Nunc, Denmark) were coated with 200 ng of purified PRP-BSA (see Example 17) in 200 μL of coating buffer (15 mM Na 2 CO 3 , 35 mM NaHCO 3 , pH 9.6) for 16 hours at room temperature. The plates were then blocked with 0.1% (w/v) BSA in phosphate buffer saline (PBS) for 30 minutes at room temperature. Serially diluted rabbit antisera raised against PRP-D15 conjugates were added to the wells and incubated for 1 hour at room temperature. After removal of the antisera, the plates were washed five times with PBS containing 0.1% (w/v) Tween-20 and 0.1% (w/v) BSA. F(ab′) 2 fragment from goat anti-rabbit IgG antibodies conjugated to horseradish peroxidase (Jackson ImmunoResearch Labs Inc., PA) were diluted (1/8,000) with washing buffer, and added onto the microtiter plates. After 1 hour incubation at room temperature, the plates were washed five times with the washing buffer. The plates were then developed using the substrate tetramethylbenzidine (TMB) in H 2 O 2 (ADI, Toronto). The reaction was stopped with 1N H 2 SO 4 and the optical density measured at 450 nm using a Titretek Multiskan II (Flow Labs., Virginia). A standard anti-PRP antiserum of known titer was included as positive control. Assays were performed in triplicate, and the reactive titer of each antiserum was defined as the reciprocal of the dilution consistently showing a 2-fold increase in O.D. value over that obtained with the pre-immune serum (Table 9).
Example 21
This Example describes the protocol used for the production of D15-specific antisera using purified D15, rD15 or N-terminal rD15 fragment.
New Zealand White rabbits (Maple Lane) and guinea pigs (Charles River) were immunized intramuscularly (IM) with a 10 μg dose of either affinity-purified native D15 (Example 13), recombinant D15 (Example 8) or N-terminal rD15 fragment (Example 11) emulsified in Freund's complete adjuvant (Difco). Animals were boosted on day 28 with another 10 μg dose of affinity-purified D15 or rD15 or rD15 fragment emulsified in Freund's incomplete adjuvant and bled on day 42 via the marginal ear vein. D15-specific polyclonal antibodies were purified from this material as described in Example 12.
Example 22
This Example illustrates the protective activity of D15-specific antisera against H. influenzae type b challenge using the infant rat model of bacteremia.
Five-day old infant rats were inoculated subcutaneously (SC) on the dorsum with 0.15 mL of two different rabbit anti-N-terminal rD15 fragments. Pre-immune sera were used as negative controls. One day after immunization, the infant rats were injected intraperitoneally (IP) with 200 colony-forming units (cfu) of Haemophilus influenzae type b Minn A strain (0.1 ml) freshly grown in brain heart infusion (BHI) medium supplemented with cofactors and diluted in PBS containing 0.5 mM MgCl 2 and 0.15 mM CaCl 2 . One day later, blood samples were collected via cardiac puncture under methoxyflurane anaesthesia and plated on chocolate agar plates. The number of bacteria per mL of blood was quantified after 24 hr. The statistical significance of differences observed in the levels of bacteremia relative to controls was analyzed by the Student's t-test. The results are summarized in Table 1.
Example 23
This Example describes the protocol used for the generation of D15-specific T-cell lines.
BALB/c (H- 2 d ) mice purchased from Charles River Animal Farm (Montreal, Canada) were individually primed subcutaneously with 20 μg of rD15 adsorbed to 1.5 mg of aluminium phosphate (alum). The animals were boosted twice with the same dose of immunogen at 3 week intervals. Ten days after the final boost, spleens of immunized mice were removed. Splenocytes were cultured at 5.75×10 5 cells per well in a final volume of 200 μL of RPMI 1640 medium (Flow Lab.) supplemented with 10% heat-inactivated fetal calf serum (Gibco), 2 mM L-glutamine (Flow Lab.), 100 U/mL) penicillin (Flow Lab.) and 5×10 −5 M 2-mercaptoethanol (Sigma) in the presence of varying concentrations (1, 10 and 100 μg per mL) of individual D15 peptides (Table 2) in 96-well plates (Nunc, Denmark). Cultures were kept in a humidified incubator in the presence of 5% CO 2 /air. Triplicate cultures were performed for each concentration of each peptide. Five days later, 150 μL of 10% rat concanavalin A culture supernatant diluted in culture medium was added to the microtiter plate wells as a source of Interleukin-2 (IL-2) to expand peptide-specific T-cells. Six days later, 150 μL of supernatant were removed from each microculture, and 150 μL of fresh IL-2 containing culture supernatant added to further expand and maintain the viability of the peptide-specific T-cells. After a further 6 day-incubation, the cells were washed three times, each time with 200 μL of culture medium.
Each set of cultures was then stimulated with the corresponding concentrations (1, 10 and 100 μg per mL) of the peptide in the presence of 2×10 5 irradiated (1,500 rad) BALB/c spleen cells in a final volume of 200 μL of culture medium. Sixty μL of supernatant were then removed from each microculture. The supernatants from each triplicate cultures set were pooled. All supernatants were assayed for IL-2, Interleukin-4 and Interferon-gamma (IFN-γ). Detections of IL-2 and IL-4 were performed using murine IL-2 and IL-4 ELISA kits purchased from Endogen Inc. (Ma, USA) respectively. Assay of IFN-γ was performed using a mouse IFN-γ ELISA kit supplied by Genzyme Corporation (Ma, USA). Test culture supernatants were assayed at 1 in 5 dilution according to the manufacturers' instructions. The results obtained are set forth in Table 7.
Example 25
This Example describes the general procedure used for the production of murine D15-specific monoclonal antibodies.
BALB/c mice were immunized intraperitoneally with 20 to 50 μg of the N-terminal rD15 fragment (Example 11) emulsified in Freund's complete adjuvant. Two weeks later, the mice were given another injection of the same amount of immunogen in incomplete Freund's adjuvant (IFA). Three days before the fusion, the mice were boosted again with the same amount of immunogen in IFA. Hybridomas were produced by fusion of splenic lymphocytes from immunized mice with non-secreting Sp2/0 myeloma cells as previously described by Hamel et al. (1987). D15-specific hybridomas were cloned by sequential limiting dilutions and screened for anti-D15 monoclonal antibody production. Eight D15-specific hybridoma cell lines were identified, expanded and frozen in liquid nitrogen. One of the hybridoma cell lines, 6C8-F6-C6, has been partially characterized. The monoclonal antibody (MAb 6C8-F6-C6) reacts with peptide D15-P8. This MAb 6C8-F6-C6 was used to prepare the D15-specific MAb affinity column and purify native D15 from H. influenzae cell paste (Example 13).
