Keratinocytes under fire of proinflammatory cytokines: Bonafide innate immune cells involved in the physiopathology of chronic atopic dermatitis and psoriasis

Specific cytokine environment deregulation plays a central role on skin morphology and innate immunity, moving towards specific pathologies and opening the way to new therapeutic strategies.

Atopic dermatitis - initiation and chemokines activation step

The skin lesions facilitate the passage of an antigen that the subject has previously been sensitized to.

Atopic dermatitis - immune response and skin lesions

TH2/TH22 immune response and other agents of atopic dermatitis After polarization, the Th2 and Th22 TL migrate to the lesion area, where they release type Th2 (IL-4, IL-5, IL-13, IL-31, TNF-α) and Th22 (IL-22) cytokines respectively. These Th2/Th22 cytokines have different functions in the immunity response.

Keratinocytes as targets for cytokines in skin inflammation

Current knowledge about the effects of different cytokine families on keratinocytes, and more particularly theirinvolvement in skin inflammation and in the development of inflammatory skin diseases such as psoriasis
