Abstract: The present invention relates to immunogenic compositions, in particular, immunogenic compositions comprising at least one peptide derived from survivin, or a functional derivative thereof. Uses of the immunogenic compositions in the treatment of cancer, in particular a cancer over-expressing survivin are also disclosed.

Abstract: The present invention is related to an in vitro diagnostic assay of enteroviruses, based on the revealing of an immunologic reaction of antigen-antibody recognition type, using antigens or epitopes thereof that do not induce antiviral neutralising antibodies but induce “facilitating” antibodies which increase the viral infection.

Abstract: The invention relates to a device for the presentation of polypeptides, a method for the preparation and the use thereof, as diagnostic tool (polypeptide chip) for miniaturized and highly parallel detection of structurally or functionally complementary molecules of said polypeptides, i.e. antibodies.

Abstract: The invention relates to a peptide mixture including at least two different peptides from the hepatitis C virus (HCV), whereby at least one of them is a peptide from the C protein binding to at least four different HLA-II molecules, the occurrence of which exceeds 5% in the Caucasian population with a binding activity <1,000 nM. Said invention also relates to the applications thereof as a drug useful in the prevention and treatment of HCV infections or as a diagnostic reagent for HCV-specific T lymphocytes.

Abstract: The invention concerns a device for presentation of peptides or of proteins, which can be used as a “polypeptide chip” for the miniaturised detection of molecules structurally or functionally complementary to the said polypeptides. This device consists of a flat support onto which the polypeptides are covalently bonded, this bonding between the polypeptides and the support resulting from the formation of a semicarbazone bond. The semicarbazone bond results in particular from the reaction between polypeptides bearing an aldehyde or ketone function and a support functionalised with semicarbazide groups. The invention also concerns the process for preparation of the supports and for attaching polypeptides onto these supports and also the use of the devices thus obtained as polypeptide chips.

Abstract: A TH1 specific CD4 T cell line, inducing an efficient CD8 response against an infection caused by an infectious agent, is obtained by removing from a donor a biological sample containing T cells; isolating the CD4+ T cells from said sample; simultaneously providing dendritic cells isolated from the same sample or another sample derived from the same donor, subjecting the previously isolated CD4+ T cells to in vitro immunisation with a peptide of a protein of the infectious agent exhibiting at least a T epitope, in the presence of the previously obtained dendritic cells; performing at least a restimulation, in the same conditions as for immunization, optionally substituting the dendritic cells with B cells from the same donor.

Abstract: The invention relates to 2 human monoclonal antibodies of sub-classes IgG1 and IgG3, against the Rhesus D antigen and to a pharmaceutical composition containing a mixture of the said antibodies, more particularly intended for the prophylaxis of the haemolytic disease of the newborn. The invention also relates to the heterohybridoma cell lines that produce these antibodies, which are filed with the "Deutsche Sammlung von Mikroorganismen und Zellkulturen" under accession numbers DSM AC 2039 and DSM AC 2040.
