Abstract:
The invention relates to a stable immunogenic product for the induction of antibodies against one or more antigenic proteins in a subject. The invention is characterized in that it comprises proteinaceous immunogenic heterocomplexes which are formed by associations between (i) antigenic protein molecules and (ii) proteinaceous carrier molecules and in that less than 40% of the antigenic proteins (i) are linked to the proteinaceous carrier molecules (ii) by a covalent bond.
Abstract:
The invention concerns a pharmaceutical composition comprising, as the active ingredient, human natural antibodies of the IgG isotype, that neutralize the activity of a human cytokine selected from VEGF, IFNα, IL-4, TNFα and TGFβ, the said neutralizing antibodies inhibiting at least 50% of the maximum biological activity induced by an amount ranging from 0.006 ng to 0.05 ng of the said cytokine in vitro.
Abstract:
The invention relates to an immunogenic or vaccine composition inducing an immune response towards the HPV-16 Papillomavirus native E7 protein, without simultaneously inducing an immunosuppression, said composition comprising, as the active ingredient, a non immunosuppressive mutated E7 protein, comprising the amino acid sequence consisting, from the N-terminal end to the C-terminal end, in: i. the 1-19 amino acid sequence of sequence SEQ ID No. 3; ii. an amino acid sequence possessing (a) the substitution of at least one amino acid, compared to the 20-29 corresponding amino acid sequence of sequence SEQ ID No. 3 or (b) the deletion of at least four consecutive amino acids, compared to the 20-29 corresponding amino acid sequence of sequence SEQ ID No. 3; and iii. the 30-98 amino acid sequence of sequence SEQ ID No.;

Abstract:
The present invention concerns a chemically modified TNF-α, and a pharmaceutical composition and a vaccine composition containing the chemically modified TNF-α which are useful for combating overproduction of native TNF-α.
Abstract:
Cytokines, which are biologically inactive in humans but remain immunogenic, are used in pharmaceutical compositions to promote a neutralizing immune response against native cytokines when administered to a subject in need thereof to treat homeostatic conditions and disorders associated with an overproduction of cytokines.

Abstract:
A method for inducing a mucosal immunity with production of secretory IgA antibodies that neutralize of block a native E7 protein originating from cancerous cells, from cells infected by a human Papillomavirus or from an immune system cell. The method includes administering to a patient in need thereof, a vaccine composition containing an active compound which is the native E7 protein, the properties of which have been inactivated by at least 70% by a physical and/or a chemical treatment, by genetic recombination or by adjuvant conditions; an inactive fragment of the immunosuppressive and/or angiogenic native E7 protein; a DNA molecule encoding the immunosuppressive and/or angiogenic native E7 protein inactivated by at least 70% by mutation; or a DNA molecule encoding an inactive fragment of the immunosuppressive and/or angiogenic native E7 protein; along with an adjuvant of mucosal immunity.
