Mechanisms in Irritant Contact Dermatitis,asis. Acute or repeated exposure to irritants determines the activation of the innate immune system with the release of pro-inflammatory cytokines and chemokines by keratinocytes and other skin resident cells. The local release of IL-1α, IL-1β, TNF-α and IL-6 activates endothelial cells and promotes
