Abstract:
A stable immunogenic product for the induction of antibodies against one or more antigenic proteins in a subject, 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 vaccines comprising as an active principle an immunogen which is a cytokinetic factor or a cell regulating factor particularly transcriptional or another type of factor with immunosuppressive/apoptotic/angiogenic properties abnormally released in the extracellular (stromal) environment by cancer or stromal cells of malignant tumors, and a pharmaceutically acceptable carrier for inducing a systemic or mucosal immune response with secretory formation of class IgC or IgA neutralizing antibodies directed against the native factor, or which is derived from such a factor and the use of said immunogen to obtain a medicine for use as anticancer drug.
Abstract:
The present invention concerns a novel method for preparing a stable immunogenic product comprising antigenic heterocomplexes of TNFα and a carrier protein, the method steps of which are disclosed in the specification.
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 3.

Abstract:
The present invention relates to methods of monitoring and improving anti-HIV therapy in a subject. More specifically, the invention discloses that the presence or absence of an anti-Tat neutralizing activity in HIV infected subjects represents a reliable marker allowing the design of appropriate treatment protocols. The present invention also shows that causing or stimulating an anti-Tat neutralizing activity in HIV infected subjects allows to delay treatment resumption.
Abstract:
An immumogenic polypeptide for inducing antibodies that neutralize the immunosuppressive and/or angiogenic activity of an E7 protein from Papillomavirus, wherein said immunogenic polypeptide consists of an E7 protein from Papillomavirus that has been inactivated so as to eliminate at least 70% of the immunosuppressive and/or angiogenic activity of the non-inactivated E7 protein. The inactivation is effected by physical and/or chemical treatments and/or by modification of the amino acid sequence of the polypeptide.
