Title of Doctoral Thesis Study of substances affecting permeability of the skin barrier The skin barrier plays a vital role in protecting the human body and enables mammals' life on dry land. The epidermis has the primary barrier function due to several cells' layers, which gradually differentiate to their final stage, the stratum corneum (SC). SC is formed by stratified keratinocytes (known as corneocytes) surrounded by a lipid matrix. This intercellular matrix consists of an approximately equimolar ratio of ceramides, free fatty acids and cholesterol. These are particular substances formed in the epidermis from their precursors during the keratinocyte's differentiation, and their arrangement into the multilamellar structure is essential for the impermeability of the skin barrier. However, some substances or factors can disrupt the skin barrier. It is usually an undesirable process of lipid disbalance resulting in disorders or diseases of the skin barrier. On the other hand, specific substances have been developed for a reversible disruption of the skin barrier (so-called enhancers) to allow drug...
