Today's understanding has fundamentally changed. The keratinocyte is now recognized as an active player in epidermal renewal with key functions in the skin's immune defence. Under homeostatic conditions, keratinocyte progenitor cells are believed to divide symmetrically or asymmetrically, that is they continue to proliferate or go on to terminally differentiate and build up the overlaying epidermis. The fine-tuned process of epidermal renewal relies on an extraordinary network of signalling cascades which are governed by keratinocyte-receptor interactions with the environment through paracrine and autocrine circuits. Opposing this coordinated homeostatic process are signals of wounding and inflammation. They alter the fate of the keratinocyte and its response to the environment through changes in adhesion molecules and surface receptors, in addition to triggering an immediate inflammatory keratinocyte response in terms of secretion of cytokines, chemokines and antimicrobial peptides. If uncontrolled, the fundamental changes imposed by wounding and inflammation upon the homeostatic programme can lead to severe skin lesions including chronic inflammatory disorders. This review will describe the current knowledge of the regulatory signalling network which allows the keratinocyte to actively impact both epidermal homeostasis and the inflammatory response.
