The cornified envelope
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.

Transcriptional control of epidermal specification and differentiation. Curr Opin Genet Dev 2004: 14: 485–491. These three reviews provide excellent overview information on various aspects of the formation of the cornified CE. 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.
WebCornification is a program of terminal differentiation followed by death, where the cells perform their function after death (physical resistance, water barrier, etc.); thus, dedicated molecules must be formed and assembled before death. Apoptosis is a defensive reaction to damage, similar to what happens in other tissues. WebGene–gene interactions in IL23/Th17 pathway contribute to psoriasis susceptibility in Chinese Han population. 7,8 In particular, the interactions between late cornified envelope proteins and corneodesmosin were also analyzed. 9 Recently, stepwise regression analysis found that LILRB2 binds to HLA-B in two large psoriasis genome-wide ...
WebThe cornified cell envelope (CE) is a protein–lipid layer that replaces the plasma membrane of corneocytes and is crucial for epidermal barrier function ().The CE consists of a complex mixture of covalently cross-linked proteins and a layer of characteristic lipids attached to the extracellular surface of the protein layer (Wertz et al. 1989; Steinert and Marekov 1995; … 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.
WebNov 25, 2024 · Envoplakin, a novel precursor of the cornified envelope that has homology to desmoplakin. This type shows small cysts with cornified material with differentiation towards the infundibulum. Some cornified cells also were present in the sample. There were still some cornified squamous epithelial cells in the model-hydrogen groups’ vaginal smear.
