Abstract: The present invention relates to an ex-vivo model of inflamed skin, an in-vitro method for obtaining the same and uses thereof for screening anti-inflammatory compounds.

Abstract: Disclosed is an ex-vivo model of inflamed skin, an in-vitro method for obtaining the same and uses thereof for screening anti-inflammatory compounds. The method includes injecting, into the dermis of a healthy skin biopsy previously taken from a mammal, a composition including an effective amount for activating dermal resident T cells of an anti-CD3 antibody and an anti-CD28 antibody; and b) incubating the injected skin biopsy obtained in step a) in the presence of a composition including an effective amount, for obtaining the polarization of the T cells activated in step a) into LTh1 and/or LTh17 and the synthesis of inflammation markers, of at least one mixture of IL-1?, IL-23, and TGF-?.
