Abstract: The invention relates to the use of a polypeptide derived from the adenylate cyclase of a Bordetella sp. (CyaA-derived polypeptide) by deletion of a segment of at least 93 amino acid residues, in particular a polypeptide derived from CyaA of Bordetella pertussis, as an immunomodifying antigen of the TH1/TH17-oriented immune response in an immunogenic composition. The invention relates to a vaccine candidate comprising such CyaA-derived polypeptide, either in an acellular immunogenic composition for active immunization against a condition causally related to the infection of a host by Bordetella sp. or in a combination composition encompassing said acellular immunogenic composition.

Abstract: The present invention relates to the field of epidermal repair. More particularly, the invention concerns the use of a molecule able to inhibit a heteromeric receptor comprising OSMR? as a subunit, for the preparation of a composition for inhibiting the expression of inflammatory factors by the keratinocytes. In particular, the invention concerns the use of antagonists and/or expression inhibitors of OSM, IL-17, TNF?, IL-31, IFN-?, and/or the OSMR? subunit, for the preparation of cosmetic or dermatologic compositions, especially for treating inflammatory skin diseases. Methods for obtaining in vitro or animal models of skin inflammation diseases are also disclosed. These models can be used for screening molecules to find new drugs to prevent or treat psoriasis and other dermatitis.

Abstract: The present invention relates to the field of epidermal repair. More particularly, the invention concerns the use of a molecule able to activate a heteromeric receptor comprising OSMR? as a subunit, for the preparation of a composition for activating in vitro and/or in vivo keratinocyte migration and/or the expression of anti-microbial peptides by the keratinocytes. In particular, the invention concerns the use of OSM and/or IL-17 and/or TNF? and/or IL-31, or agonists thereof, for the preparation of cosmetic or dermatologic compositions.
