Abstract: The invention is directed to means, based on CyaA-carried polypeptide(s), for use in the immunotherapeutic treatment of first determined pathological condition(s) diagnosed in a mammalian host by eliciting a T cell immune response against a first group of epitopes contained in said polypeptide(s) and in the prophylaxis against second determined pathological condition(s) in the same mammalian host by eliciting a T cell memory immune response against a second group of epitopes contained in said polypeptide(s), said immune responses being obtained after administration of said vector-carried polypeptide(s) into said host, wherein said prophylaxis against second determined pathological condition(s) is not observed when said second group of epitopes is not contained in said administered vector-carried polypeptide(s).
Abstract: The invention relates to a chimeric protein comprising or consisting of, from N-terminal to C-terminal, (a) a N-terminal part of a Bordetella CyaA protein (b) a heterologous polypeptide comprising antigens originating from different HPVs, and (c) a C-terminal part of a Bordetella CyaA protein. The invention also relates to a polynucleotide encoding this chimeric protein. A composition comprising at least one chimeric protein(s) of the invention and the prophylactic and/or therapeutic uses of said composition are also part of the invention.

Abstract: The present invention relates to a composition for eliciting a specific cytotoxic T lymphocyte (CTL) response against T cell epitopes in a mammal, which comprises a compound provoking lymphocytopenia, a molecule having selective affinity for professional antigen presenting cells (APC), wherein said molecule is associated to said T cell epitope, and optionally, a pharmaceutical acceptable carrier. Advantageously, the composition further contains an adjuvant. Said composition may be used in anti-infections and anti-cancer therapies.
Abstract: The invention relates to a recombinant protein comprising one or several polypeptides bearing one or several epitopes of one or several HPV antigens, said polypeptides being inserted in the same or different permissive sites of an adenylate cyclase (CyaA) protein or of a fragment thereof, wherein said CyaA fragment retains the property of said adenylate cyclase protein to target Antigen Presenting Cells. It also concerns polynucleotides encoding the same. The recombinant protein or the polynucleotide can be used for the design of therapeutic means against HPV infection or against its malignant effects.
