Formation of the cornified envelope

WebThe cornified envelope, a layer of ~ 10–15 nm thickness, is the ultimate differentiation product of epidermal keratinocytes composed of enucleated corneocytes to which a special set of lipids are covalently bound ( Candi et al., 2005; Rice and Green, 1977; Steinert and Marekov, 1995 ). WebIt is revealed that abnormal cornified cell envelope synthesis is significantly involved in the pathophysiology of certain inherited keratodermas and reflects perturbations in the complex yet highly orderly process of cornification cell envelope formation in normal skin biology.
