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.

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 invention concerns a derivative of viral regulatory protein or a fragment of viral regulatory protein or of the alpha interferon or a fragment of alpha interferon, which is carboxymethylated, a method for preparing, use of the resulting product in a method of treatment for the human or animal body, a pharmaceutical composition and a vaccine containing as active principle, at least one of the carboxymethylated proteins or fragments.

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.
