The invention disclosed herein relates to the field of epidermal repair and skin innate immunity. More particularly, the invention concerns the use of a mix of cytokines to inhibit keratinocyte differentiation, activate skin innate immunity, increase the expression of anti-microbial peptides, and improve epidermal repair. In particular, the invention concerns compositions comprising at least IL-17, TNF&#x3b1; and OSM that can be formulated for topical administration for cosmetic or dermatologic use.

Method for increasing the expression of anti-microbial peptides by keratinocytes comprising administering a composition comprising IL-17, TNF-alpha and OSM

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&#x3b2; 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&#x3b1; and/or IL-31, or agonists thereof, for the preparation of cosmetic or dermatologic compositions.
