Definitions
- the present invention relates to a method for improving the immunogenicity of an immunogen, antigen or hapten, by coupling with a small support peptide. More particularly, the present invention relates to a process for the preparation of an immunogenic complex as well as the complexes capable of being obtained by such a process, and the use of such complexes as a medicament for increasing the immunogenicity of an immunogen .
- the invention notably comprises a support peptide coupled with a peptide derived from protein G of the Respiratory Syncytial Virus (RSV) and its use as a vaccine for the treatment of respiratory infections linked to RSV.
- RSV Respiratory Syncytial Virus
- the immune system is a network of humoral and cellular components which interact to allow the host to differentiate the self from the non-self in order to eliminate it, as well as the agents considered pathogenic. To do this, the immune system has developed two mechanisms that act in concert: innate immunity and acquired immunity.
- innate immunity are grouped physical barriers (skin, mucosa, ...), cells (monocytes / macrophages, polynuclear, NK cells, ...) and soluble factors (complement, cytokines, proteins of the acute phase, ...) involved or produced in response to an attack.
- the responses of innate immunity are rapid but are neither specific nor memorized.
- the cellular mediators of acquired immunity are the T and B lymphocytes. Their interaction allows in particular the production of immunoglobulins by the latter. Unlike the responses of innate immunity, those of acquired immunity are specific, adaptable and memorizable. Indeed, the penetration of an antigen into a new organism establishes an immune response called primary response, during which will multiply long-lived lymphocytes (T and B), called memory lymphocytes. Thanks to these cells, during a second penetration of the same antigen, the immune reaction, called secondary, will be faster and more intense. For a primary response to take place, the antigen must first be picked up and primed by the antigen presenting cells, to be presented to T cells.
- T and B long-lived lymphocytes
- vaccines The purpose of vaccines is to protect the host by preventing or limiting the invasion of pathogens.
- all vaccines on the market fulfill this role by stimulating the production of antibodies.
- carrier protein a protein having T epitopes capable of interacting with T lymphocytes.
- the best known vaccine carrier proteins are diphtheria and tetanus toxoids. Among these carrier proteins, mention may also be made of the protein known as
- BB fragment of the Streptococcus protein G, capable of binding albumin, fragment corresponding to residues 24 to 242 of the sequence SEQ ID No. 1.
- This protein makes it possible to trigger an earlier and more intense primary antibody response vis -in relation to the vaccine antigen associated with it (Libon et al., Vaccine, 17 (5): 406-41,1999). As such, reference may also be made to the international patent application published under the number WO 96/14416.
- the present invention aims to provide an alternative to carrier proteins which would, as will become apparent from the description below, overcome all of the drawbacks associated with the use of such a carrier protein. More particularly, the present invention makes it possible to limit the side effects linked to the presence of a relatively large carrier protein while allowing high production yields to be obtained.
- the inventors have highlighted an alternative to the use of carrier proteins. More particularly, the inventors have characterized a method for improving the immunogenicity of an immunogen based on the identification of a peptide, hereinafter called carrier peptide, very small in size and therefore non-immunogenic, facilitating their synthesis and / or synthesis of complexes immunogen-support peptide in which they participate.
- the present invention relates to a process for the preparation of an immunogenic complex in which an immunogen, antigen or hapten, is combined with a support peptide to form said immunogenic complex, characterized in that said support peptide consists of a peptide of less than 10 amino acids comprising at least the peptide fragment of 3 amino acid residues of sequence SEQ ID No. 2 (Met-Glu-Phe).
- immunogen any substance capable of inducing an immune response.
- the immunogen is preferably a protein, a glycoprotein a lipopeptide, or any immunogenic compound comprising in its structure a peptide of at least 5 amino acids, preferably at least 10, 15, 20, 25, 30 or 50 amino acids, compound capable of causing an immune response, in particular capable of inducing the production of specific antibodies directed against this peptide after its administration in a mammal.
- the terms polypeptides, polypeptide sequences, peptides and proteins are interchangeable.
- the expression peptide support is to be differentiated from the expression carrier protein.
- a carrier protein is characterized by a large size (218 amino acids for the BB protein) and especially the presence of T epitopes capable of binding to T receptors for the antigen present on the surface of T lymphocytes.
- the peptide support object of the present invention differs from a carrier protein because of its very small size (less than 10 amino acids) and also because it does not have T epitopes.
- the object method of the present invention makes it possible to obtain immunological complexes making it possible to improve the immunogenicity of an immunogen whose production is easier or with higher production yields.
- the complex comprising the support peptide which is the subject of the invention being much smaller in size than complexes comprising carrier proteins of the prior art, it is easier to produce by peptide / chemical synthesis or any other known technique.
- the immunogenic complexes according to the invention which are the subject of the invention make it possible to eliminate, at the very least to limit, the undesirable effects linked to the very nature of the carrier protein. It is recognized by those skilled in the art that a relatively large carrier protein, such as BB, is likely to be the basis of unwanted immune responses.
- the invention provides an advantageous alternative to the use of carrier proteins. Indeed, due to its reduced size, the support peptide has no, at least very little, chance of being the cause of side or undesirable effects.
- the support peptide of less than 10 amino acids comprises at least the peptide coded by SEQ ID No. 2 and consists of at most 8 amino acids, preferably at most 5 amino acids, and even better 4 amino acids.
- the support peptide of less than 10 amino acids which is the subject of the present invention consists of the peptide of sequence SEQ ID No. 2.
- association between said support peptide and the immunogen can be carried out by any coupling technique known to a person skilled in the art making it possible to preserve the integrity as well as the immunogenic properties of the immunogen. More particularly, the process which is the subject of the invention is characterized in that said association consists of covalent coupling.
- covalent coupling it is necessary to understand chemical coupling or protein fusion by the so-called recombinant DNA technique (fusion protein obtained after translation of a nucleic acid coding for the fusion protein (immunogenic complex) by a host cell (eukaryote or prokaryotic) transformed with said nucleic acid.
- Said support peptide can be coupled to the N-terminal or C-terminal end said immunogen when said iminunogen is a peptide.
- Preferably said support peptide is coupled to the N-terminal end of said immunogen.
- Immunogenicity can be produced by recombinant DNA techniques, in particular by insertion or fusion into the molecule of DNA coding for the support, DNA coding for the immunogen.
- the covalent coupling between the support peptide and the immunogen is carried out chemically, according to techniques known to those skilled in the art.
- the subject of the invention is also a method according to the invention in which said immunogenic complex is obtained by genetic recombination (recombinant protein) using a nucleic acid resulting from the fusion of (or insertion into) the DNA molecule coding for the support peptide with DNA coding for
- the method according to the invention comprises, in one of its modes of implementation, a step of production of the complex, by genetic engineering, in a host cell.

Nucleic acid molecules are used which are capable of directing the synthesis of the antigen in the host cell.
- promoter sequences include promoter sequences, functionally linked secretion signal and sequence coding for a membrane anchoring region, which will be adapted by those skilled in the art.
- the immunogen can in particular be derived from a surface glycoprotein of human RSV type A or B, or from bovine RSV, in particular chosen from proteins F and G.
- the immunogen consists of a polypeptide encoded by a sequence between residues 130-230 of the peptide sequence of the G protein of RSV or by any sequence having at least 80% identity with said peptide sequence, preferably 85%, 90%, 95% or 98% identity with the sequence between residues 130-230 of the peptide sequence of said protein G, or one of its fragments of at least 10 consecutive amino acids, preferably at least 15, 20, 25, 30 or 50 amino acids, capable of inducing the production of specific antibodies directed against this fragment after its administration in a mammal.
- percentage of identity or “percentage of homology” (the two expressions being used interchangeably in the present description) between two nucleic acid or amino acid sequences within the meaning of the present invention, is intended to denote a percentage of identical nucleotides or amino acid residues between the two sequences to be compared, obtained after the best alignment (optimal alignment), this percentage being purely statistical and the differences between the two sequences being distributed randomly and over their entire length.

USA 85: 2444], by means of computer software using these algorithms (GAP, BESTFIT, FASTA and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer Group, 575 Science Dr., Madison, WI, or by BLAST comparison software N or BLAST P).
- the percentage of identity between two nucleic acid or amino acid sequences is determined by comparing these two optimally aligned sequences in which the nucleic acid or amino acid sequence to be compared may include additions or deletions compared to the reference sequence for optimal alignment between these two sequences.
- the percentage of identity is calculated by determining the number of identical positions for which the nucleotide or the amino acid residue is identical between the two sequences, by dividing this number of identical positions by the total number of positions in the comparison window. and multiplying the result obtained by 100 to obtain the percentage of identity between these two sequences.
