The lipid organisation in the skin barrier.
The main function of the skin is to protect the body against exogenous substances. The skin barrier is located in the outermost layer of the skin, the stratum corneum. This layer consists of keratin enriched cells embedded in lipid lamellae. These lamellae form the main barrier for diffusion of substances through the skin. In diseased skin the barrier function is often impaired. For a full unde...
متن کاملThe role of ceramide composition in the lipid organisation of the skin barrier.
The lipid lamellae in the stratum corneum (SC) play a key role in the barrier function of the skin. The major lipids are ceramides (CER), cholesterol (CHOL) and free fatty acids (FFA). In pig SC at least six subclasses of ceramides (referred to as CER 1, 2-6) are present. Recently it was shown that in mixtures of isolated pig SC ceramides (referred to as CER(1-6)) and CHOL two lamellar phases a...
متن کاملThe skin barrier from a lipid perspective.
This contribution summarises the results from a number of investigations undertaken in the spirit of the Domain Mosaic Model proposed by Forslind in 1994. Atomic Force Microscopy (AFM) studies on the two-dimensional phase behaviour of some stratum corneum lipids revealed phase separation of the lipids in the typical case and the ability of cholesterol to reduce the line tension between phases. ...
