Definitions
- the present invention is related to the field of medicine, particularly with the development of vaccine compositions, of preventive or therapeutic application, which allow an increase in the quality of the immune response against vaccine antigens in diseases of diverse origin.
- the inclusion bodies can be easily separated, solubilized with denaturing agents, such as guanidium chloride or urea, and then renatured through a process such as dilution or dialysis.
- denaturing agents such as guanidium chloride or urea
- renaturation processes include inhibition of aggregation by applying low molecular weight additives and renaturation in matrices (Misawa S. and Kumagai I. (1999) Refolding of therapeutic proteins produced in Escherichia coli as inclusion bodies. Biopolymers 51: 297-307).
- the P2 protein of Haemophilus influenzae which is one of the majority immunogenic proteins of the outer membrane, was renaturated in a solution that included high concentrations of salt and calcium ions (Pullen JK, et al. (1995) Production of Haemophilus influenzae type-b porin in Escherichia coli and its folding into the trimeric form. Gene 152: 85-8).
- Rhodabacter capsulatus porin protein was chemically modified with methoxypolyethylene glycol-succinimidyl carbonate to yield a water soluble conjugate thereof.
- the renaturation of the conjugate was studied by sequence addition! of trifluoroethanol to lower the dielectric constant, which was not achieved.
- the protein was finally renatured by addition of hexafluoro-2-propanol between 5 and 10% (Wei J., Fasman GD (1995) A poly (ethylene glycol) water-soluble conjugate of porin: refolding to the native state. Biochemistry 34: 6408-15).
- PorA Two types of PorA, P1.6 and P1.7,16 of meningococcus, folded in vitro after overexpression and isolation from E. coli. Said porins were folded efficiently by rapid dilution in an appropriate buffered solution containing the detergent n-dodecyl-N, N-dimethyl-1-ammonium-3-propanesulfonate (Jansen O, et al. (2000) Biochemical and biophysical characterization of in vitro folded outer membrane porin PorA of Neisseria meningitidis. Biochim Biophys 1464: 284-98).
- the inclusion in membranes formed by lipid bilayers is a strategy used in the renaturation of porin proteins and other integral proteins of membrane, obtained through genetic engineering.
- the main outer membrane protein of Chlamydia psittaci and Chlamydia pneumoniae was solubilized from inclusion bodies using 2% OG and 1mM dithiothreitol, before incorporating it into a lipid bilayer (Wyllie S., et al. (1999) Single channel analysis of recombinant major outer membrane protein porins from Chlamydia psittaci and Chlamydia pneumoniae. FEBS Lett 445: 192-96).
- the outer membrane proteins of Escherichia coli OmpF and OmpA were renaturated by dilution in a dispersion of lipid vesicles or detergent / lipid vesicles (Surrey T., et al. (1996). Folding and membrane insertion of the trimeric beta-barrel protein OmpF. Biochemistry 35: 2283-88).
- the meningococcal Opc gene was cloned and expressed at high levels in E coli.
- the protein was purified by affinity chromatography, incorporated into liposomes and micelles of the Zwittergent detergent.
- MFLA Mono Phosphoryl Lipid A
- the affinity purified protein was either adjuvant with AI (OH) 3 adjuvant, or presented in liposomes.
- Immunization of the recombinant protein in liposomes induced antibodies with great avidity for the native protein, which reacted with the intact meningococcus and inhibited the binding of protective antibodies (Christodoulides M., et al. (1998) Immunization with recombinant class 1 outer-membrane protein from Neisseria meningltidis: influence of liposomes and adjuvants on antibody avidity, recognition of native protein and the induction of a bactericidal immune response against meningococci. Microbiology 144: 3027-37).
- the porB gene from a N.
- meningitidis strain expressing the PorB3 protein was cloned and inserted into the pRSETB vector and the protein was expressed at high levels in the E. coli host.
- the recombinant protein was purified to homogeneity by affinity chromatography and used for immunization after incorporation into liposomes and micelles of Zwittergent detergent or sulfobetaine.
- the serum produced by the liposomes and the micelles showed greater reactivity with the native protein (Wright JC, et al (2002). Immunization with the Recombinant PorB Outer Membrane Protein Induces a Bactericidal Immune Response against Neisseria meningitidis. Infec ⁇ Immun. 70: 4028- 3. 4).
- Neisseria meningitidis a Gram negative diplococcus whose only host is man, is the causative agent of meningococcal meningitis. This bacterium is usually found in an asymptomatic carrier state in the population, this being the most common route for its microbiological isolation.
- Various strategies have been developed with the aim of obtaining a vaccine preparation that satisfies the necessary requirements to protect the population against this disease. For this, the capsular antigens whose immunological specificity has allowed the classification of this microorganism in serogroups have been taken into account.
- Serogroup B unlike the rest, continues to be an important cause of endemic and epidemic meningococcal disease, largely due to the lack of effective vaccines against it.
- Product of the low immunogenicity of serogroup B polysaccharide (Finne J., et al. (1987) An monoclonal IgG antibody to group B meningococci cross-reacts with developmentally regulated polysialic acid units of glycoproteins in neural and extraneural tissues. J. Immunol. 138: 4402-07), the development of vaccines against this serogroup has concentrated on the use of subcapsular antigens.
- Vaccines composed of VME were significantly more immunogenic parenterally than PME aggregates and this immunogenicity was initially explained by increased adsorption to the adjuvant aluminum hydroxide (Wang LY and Frasch CE. (1984) Development of a Neisseria meningitidis group B serotype 2b protein vaccine and evaluation in a mouse model, Infec ⁇ Immun. 46 (2): 408-14). Subsequently, the effectiveness of EMV vaccines has been attributed to the presentation of PMEs, arranged in their natural conformation, to allow the generation of bactericidal antibodies, at least in adolescents and adults. Antibody responses generated increased meningococcal opsonophagocytosis.
- the precise formulation of the vaccines has a significant impact on immunogenicity, with large differences from one producer to another depending on the strain and / or the methodology used ( Lehmann AK, et al. (1991) Immunization against serogroup B meningococci. Opsonin response in vaccinees as measured by chemiluminescence. APMIS 99 (8): 769-72; Gómez JA, et al. (1998) Effect of adjuvants in the sotypes and bactericidal activity of antibodies against the transferrin-binding proteins of Neisseria meningitidis.
- PorA porin approximately 42 kDa, has been shown by sequence analysis that its variability is exclusively concentrated in two of the 8 exposed protein loops (VR1 and VR2). Variation of these regions has been used in subtyping of meningococcal strains (Abdillahi H.
- the present invention solves the aforementioned problem by providing a method for incorporating antigens into proteoliposomes, where said antigens form a complex with a preparation of Gram negative bacteria outer membrane proteins, this complex being generated by co-renaturation and keeping the structure intact. vesicular proteoliposome.
- the method includes a preparation of Gram negative bacteria outer membrane proteins, obtained from species of the Neisseriaceae family or Bramhamella catarrhalis, with those including Neisseria meningitidis and Neisseria lactamica being especially preferred.
- the protein antigen that forms part of the complex is of natural, recombinant or synthetic origin.
- the invention also relates to the vaccine combination derived from the method described above and comprising a complex formed by a preparation of Gram negative bacteria outer membrane proteins, made from species of the Neisseriaceae family or from Bramhamella catarrhalis, and a protein antigen of natural, recombinant or synthetic origin, where this complex is generated by co-renaturation and keeps the vesicular structure of the proteoliposome intact.
- the vaccine compositions can be administered parenterally or mucosally.
- a particularly important aspect of the invention relates to the addition to the above-mentioned vaccine compositions of bacterial polysaccharides, conjugated bacterial polysaccharides and nucleic acids as antigens.
- the prophylactic or therapeutic use of the combinations described above in humans is also part of the present invention.
- compositions protein antigens are renatured by insertion into proteoiiposomal vesicles, in order to achieve their correct folding.
- Said compositions have new properties that result from the generation of the complex, which originates in such a way that the vesicular structure remains intact.
- the mucosal administration of said compositions can generate a systemic immune response of similar intensity and superior quality to that obtained with conventional vaccine formulations that use alumina as an adjuvant. Furthermore, immunization by this route is capable of generating a powerful response at the mucosa level, characterized by high levels of IgA-type antibodies.
- the present invention in contrast to the state of the prior art, is useful for achieving adequate renaturation of protein antigens without them having to be included in artificial, chemically modified lipid bilayers. or mixed with chemical compounds of inorganic origin.
- a more effective functional immune response is obtained, in terms of the quality of the antibodies that are generated against the antigen of interest, due to its optimal presentation to the immune system.

- the E. coli clone expressing the gene coding for said recombinant protein was grown in LBA liquid medium for 8 hours at 37 ° C, in the presence of kanamycin. After centrifugation, the cell pellet was subjected to ultrasonic disruption, and the insoluble fraction containing the recombinant protein was subjected to the following manipulations:
- the protein was purified by chromatographic methods. After extraction of the recombinant protein at 10 mg / ml, it is diluted in TE buffer to bring the Urea to 4M and it is subjected to an ion exchange gel filtration process in Q-Sepharose. The purity of the resulting protein is shown in Figure 2.
- variants V and VI the recombinant protein was renatured by dilution in solution B, then mixed with PME and centrifuged at 125 OOOg.
- the incorporation of the recombinant protein in the vesicles was initially evidenced by electrophoretic analysis of the studied variants.
- the presence of a protein band with the same size as the recombinant protein in some of the variants was evidence of the incorporation obtained. This was corroborated in the immunoidentification of the band with the anti-P1.16 monoclonal antibody, a signal that is indicated by the upper arrow in Figure 3B.
- Table 3 shows the incorporation percentage determined by a capture ELISA using the anti-P1.9 monoclonal antibody and the peroxidase-conjugated anti-P64k anti-terminal antibody.

Table No. 3 Percentage of incorporation obtained for the studied variants
- Example 3 Evaluation of the immune response obtained against the recombinant protein PorA inserted in the proteoliposome of Neisser ⁇ a meningitidis.
- the recombinant proteins P1.9, P1.16 and P1.7.16 were inserted into the proteoliposome. Said preparations were used as a control in an immunization scheme with the objective of evaluating the immune response generated against the P1.7,16,9 protein.
- These antigens were cloned and expressed in E. coli, from the genome of N. meningitidis strains, which express epitopes corresponding to said subtypes, given the variability presented by the PorA or P1 protein, as it is known interchangeably.
- Proteins were renatured by dilution in 1M Tris-HCI with 2mM EDTA, 1.2% Sodium Deoxycholate and 20% sucrose, and incubated with the outer membrane protein preparation 1.5 h at room temperature before centrifugation. This was the method selected hereafter for the incorporation of protein antigens in the outer membrane of gram negative bacteria.

- Figure 5 shows the result of immunoidentification performed with monoclonal antibody 1-33. that recognizes P1.9, which evidenced the incorporation of the recombinant proteins P1.9 and P1.7,16,9.
- the antibody titer (IgG) against the recombinant protein P1.7,16,9 was determined by ELISA in the sera.
- the recognition of the corresponding antigens present in PME preparations of N. meningitidis strains expressing the aforementioned P1 subtypes was evaluated by the antisera resulting from the described immunization scheme.
- FIG. 6 graphically represents the results of the immunization scheme, in terms of antibody levels against the recombinant protein P1.7,16,9. This test was performed using a mixture of the individual sera per group. As observed, immunization with each of the four recombinant proteins incorporated into the proteoliposomes induced antibodies against the protein. chimeric, which includes all the subtypes of P1 under study. The highest levels of antibodies against this protein were induced after immunization with the antigen itself.
- the bactericidal antibody titers obtained against strains expressing P1.9, P1.16, P1.7, and P1.7,16, respectively, are shown in Figure 8. As can be seen, the antibodies obtained by immunizing with P1.7,16,9 renatured in the proteoliposome of the CU385 strain, had bactericidal activity against all the heterologous strains that contained the subtypes included therein.
- Example 4 Insertion of the TbpB protein in the proteoliposome. Obtaining and evaluating a PorA-TbpB-VME complex by co-renaturation, and evaluating the immune response against it.
- the TbpB protein is a human transferrin receptor protein that is expressed by N. meningitidis and constitutes an antigen of vaccine interest.
- the antigenic features of the TbpB protein cause the N. meningitidis strains to be classified into two main families: isotype I and isotype II, which differ according to the molecular mass of said protein.
- the TbpB protein corresponding to strain B16B6 was cloned and expressed in E. coli. From the biomass obtained, the recombinant protein was purified to homogeneity using widely described chromatographic procedures. In order to achieve the renaturation of this recombinant TbpB, belonging to isotype I, a proteoliposome obtained from strain CU385 was used, which expresses a TbpB that belongs to the other isotype, so that both TbpB are antigenically differentiated.
- TbpB protein For the renaturation of the recombinant TbpB protein, it was incubated with the proteoliposome for 4h at 37 ° C, or incubated for 4h with recombinant PorA (P1.16) and the proteoliposome at 37 ° C and in a third variant it was incubated by 1h at 4 ° C with the P1.16 and proteoliposome mixture, previously incubated for 4h at 37 ° C. In all the variants the preparations were finally centrifuged at 125 OOOg. For the evaluation of the immune response, 50 female Balb / C mice from 8 to 10 weeks old, divided into 5 groups (of 10 animals each), were immunized with the immunogens described in Table 5.

- a simple classification analysis of variance was used.
- the Newman-Keuls multiple comparison test was performed in comparing the means of the treatments in the necessary combinations.
- Figure 13 graphically represents the results of the immunization scheme, in terms of levels of antibodies against the P1.16 protein present in meningococcal VME.
- the alumina-adjuvant recombinant protein was unable to induce antibodies that recognized native 16-subtype porin.
- Example 7 Evaluation of the immune response induced by a formulation composed of recombinant TbpB, incorporated into the CU385 proteoliposome, and a vector for immunization with DNA.
- a plasmid was constructed that carries the gene that encodes the P6 protein of
- Haemophilus influenzae which was named pELIP6 and was used in DNA immunization experiments.
- the material necessary to include said plasmid was purified in formulations containing the recombinant TbpB protein (B16B6) inserted into the proteoliposome of the N. meningitidis CU385 strain.
- the vector pELl was obtained, similar to the plasmid pELIP ⁇ but lacking the coding segment for P6.
- 40 female Balb / C mice, 8-10 weeks old were used, which were divided into five groups (of 8 animals each), as shown in Table 8.
- Sera extracted at the end of the scheme the antibody titer against the recombinant TbpB protein was determined. Sera were also titrated to quantify the levels of antibodies against the P6 protein. Said recombinant antigen was previously purified from a genetically modified E coli strain.
- Figure 14 graphically represents the results of the immunization scheme, in terms of levels of antibodies against the recombinant TbpB protein and recombinant P6, respectively.
- the highest antibody titers against the recombinant TbpB protein were induced in the variants in which the protein was incorporated into the proteoliposome of a heterologous strain.
- the presence of plasmid pELIP ⁇ in the formulation did not affect the immunogenicity of the recombinant TbpB protein.
- the plasmid coding for P6 produced an antibody response at the expected level, after immunization with it in the presence of the TbpB-VME complex. This response was higher (with statistical significance) than that achieved by the group that had a similar formulation, but that contained the vector pELl.
