Abstract

Stratum corneum lipid liposomes formed from epidermal ceramides (40%), cholesterol (25%), palmitic acid (25%), and cholesteryl sulfate (10%), when exposed to hypertonic medium, form flattened liposomes. Epidermal acylglucosyl-ceramides (AGCs) and acylceramides (ACs) cause aggregation and fusion of these flattened vesicles. This could serve as a model to study (a) the fusion of membranous disks in the intercellular space of the stratum corneum and (b) the roles of AGCs and ACs in the assembly of lamellar structures in the epidermis.
