The cornified envelope
WebThe impermeable cornified envelope provides structural support to the cell and resists invasion by microorganisms and deleterious environmental agents; however, it does not appear to have a significant role in regulating permeability. The stratum corneum has also been called the stratum dysjunctum. WebBy database analysis to identify human orthologs of mouse genes encoding late envelope proteins (LEPs), Marshall et al. (2001) identified LCE5A, which they called LEP18. Using real-time PCR, Jackson et al. (2005) detected very low LCE5A expression in adult and fetal skin and esophagus, but not in vulva or tongue. Expression was also detected in heart.

WebThe cornified envelope replaces the plasma membrane of differentiating keratinocytes and consists of keratins that are enclosed within an insoluble amalgam of proteins, which are crosslinked by transglutaminases and surrounded by a lipid envelope. WebThe cornified cell envelope is a highly insoluble and extremely tough structure formed beneath the cell membrane during terminal differentiation of keratinocytes. Its main function is to provide human skin with a protective barrier against the environment. Is …
WebThe formation of a cornified envelope (CE) is a major event in the terminal differentiation of epidermal cells. Nomarski contrast microscopy of the envelopes purified from different sources reveals the existence of two major, but morphologically distinct classes: the very irregularily shaped fragile type CEf, and the polygonal rigid type CEr.
