Glycosphingolipids (GSLs) are composed of hydrophobic ceramide and hydrophilic
sugar chains. GSLs cluster to form membrane microdomains (lipid rafts) on plasma
membranes, along with several kinds of transducer molecules, including Src family
kinases and small G proteins. However, GSL-mediated biological functions remain
unclear. Lactosylceramide (LacCer, CDw17) is highly expressed on the plasma
membranes of human phagocytes and mediates several immunological and inflammatory
reactions, including phagocytosis, chemotaxis, and superoxide generation. LacCer
forms membrane microdomains with the Src family tyrosine kinase Lyn and the G?i
subunit of heterotrimeric G proteins. The very long fatty acids C24:0 and C24:1
are the main ceramide components of LacCer in neutrophil plasma membranes and are
directly connected with the fatty acids of Lyn and G?i. These observations
suggest that the very long fatty acid chains of ceramide are critical for
GSL-mediated outside-in signaling. Sphingosine is another component of ceramide,
with the hydrolysis of ceramide by ceramidase producing sphingosine and fatty
acids. Sphingosine is phosphorylated by sphingosine kinase to
sphingosine-1-phosphate, which is involved in a wide range of cellular functions,
including growth, differentiation, survival, chemotaxis, angiogenesis, and
embryogenesis, in various types of cells. This review describes the role of
ceramide moiety of GSLs and its metabolites in immunological and inflammatory
reactions in human.
