Abstract: The present invention relates to an in vitro method for evaluating the prognosis of an autoimmune or chronic inflammatory disease in an individual, comprising the following steps: a) determining (i) the level of an anti-IL-17 autoanitibody and/or (ii) the level of an [IL-17/anti-IL-17 autoantibody] complex in a biological sample of the individual, and b) comparing the level of autoantibody and/or of complex determined in step a) with a reference value, the comparison being indicative of the prognosis of an autoimmune or chronic inflammatory disease in said individual.

Abstract: The invention relates to an in vitro process for determining the functional IL-17 pro-inflammatory dependent level (IPDL) of a biological sample, comprising the following steps: a) measuring the level of an inflammatory marker produced by IL-17-sensitive cells incubated in the presence of a biological sample, b) measuring the level of said inflammatory marker produced by said cells incubated in the presence of a biological sample, in the presence of antibodies which neutralize the biological activity of IL-17, and c) determining the IPDL level, which is the difference between the level of said inflammatory marker measured in step a) and the level of said inflammatory marker measured in step b).

Abstract: The present invention relates to a viral vector for expression of the cell death-inducing PUMA protein, for use in gene therapy, for example for the treatment of rheumatoid arthritis. This vector consists in particular of a recombinant adenovirus expressing the gene encoding the PUMA protein and of a recombinant baculovirus containing a coxsackie-adenovirus receptor (CAR).

Abstract: Method for determining a level of activity of a biological pathway from a biological sample of a patient suffering from a pathology, the method comprising the steps of: measuring the level of expression of at least three genes from a group of individuals, control individuals or patients, for which the biological pathway is inactive, the at least three genes being associated to the biological pathway, for establishing a negative reference, and measuring level of expression of the at least three genes from a group of individuals, control individuals or patients, for which the biological pathway is active, for establishing a positive reference, and measuring the level of expression of the at least three genes of the patient in the sample.

Abstract: The present invention concerns an in vitro method for determining, from a biological sample, the response to a patient suffering from rheumatoid arthritis to a treatment directed against a cytokine involved in the inflammatory process of the disease, characterized in that it consists in measuring the expression of the gene encoding synoviolin.

Abstract: The invention relates to the use of at least one interleukin-17 inhibitor and/or of at least one IL-17 receptor inhibitor, for the manufacture of a medicament for inhibiting, preventing or treating gastric cancer.

Abstract: The present invention relates to the use of at least one interleukin-17F inhibitor and/or of at least one IL-17 receptor inhibitor, for the manufacture of a medicament for inhibiting, preventing or treating rheumatoid arthritis. The invention also relates to a pharmaceutical composition comprising, as active ingredient, at least one interleukin-17F inhibitor and/or at least one IL-17 receptor inhibitor in combination with a pharmaceutically appropriate carrier, and also to the use thereof for inhibiting, preventing or treating rheumatoid arthritis.
