Charles University, Faculty of Pharmacy in Hradec Králové Department of Pharmaceutical Technology Author: Zuzana Jarešová Supervisor: PharmDr. Andrej Kováčik, Ph.D. Consultant: PharmDr. Lukáš Opálka, Ph.D. Title of diploma thesis: STUDY OF FREE SPHINGOID BASES IN SKIN BARRIER The skin barrier, localized in the stratum corneum (SC), consists of corneocytes and an intercellular matrix formed from three types of lipids - ceramides, free fatty acids, and cholesterol, represented in an equimolar ratio. The overall arrangement of lipids is organized and highly specialized. Ceramides are structurally formed from the fatty acid acyl attached to a sphingoid base. In minor but not insignificant amounts, free sphingoid bases can also be found in the skin barrier. Several studies show that there is an increased concentration of free sphingoid bases in skin barrier disorders, such as atopic dermatitis. Although it is assumed that the presence of free sphingoid bases affects the skin barrier, it is not elucidated the way of their participation till today. The lack of studies or their diverse results leads us to the main goal of this thesis - to clarify how free sphingoid bases influence the skin barrier. In this work, the model membranes were prepared by the isolation of human SC ex vivo. Sphingosine (S),...
