Abstract

Sphingolipids were discovered more than a century ago in the brain. Cerebrosides and sphingomyelins were named so because they were first isolated from neural tissue. Although glycosphingolipids and especially those containing sialic acid in their oligosaccharide moiety are particularly abundant in the brain, sphingolipids are ubiquitous cellular membrane components. They form cell- and species-specific profiles at the cell surfaces that characteristically change in development, differentiation, and oncogenic transformation, indicating the significance of these lipid molecules for cell-cell and cell-matrix interactions as well as for cell adhesion, modulation of membrane receptors and signal transduction. This review summarizes sphingolipid metabolism with emphasis on aspects particularly relevant in neural cell types, including neurons, oligodendrocytes and neuroblastoma cells. In addition, the reader is briefly introduced into the methodology of lipid evaluation techniques and also into the putative physiological functions of glycosphingolipids and their metabolites in neural tissue.
