Ceramide Phosphates

Ceramide-1-phosphate is one of several important phosphosphingolipids in mammalian cells and is generated by the phosphorylation of ceramide by the enzyme ceramide kinase. Ceramide-1-phosphate is currently attracting much attention in research due to its important cellular functions like its role in inflammation, as a novel second messenger, and its involvement in cellular processes like phagocytosis, potassium channel function, inflammatory responses, cell survival, and tumorigenesis.1 The first reported biological action of ceramide-1-phosphate was its ability to stimulate DNA synthesis and cell division. Ceramide-1-phosphate was also found to be mitogenic for both fibroblasts and macrophages.2,3 Another important function of ceramide-1-phosphate is its promotion of cell survival. Ceramide-1-phosphate stimulates the phosphatidylinositol 3-kinase (PI3-K)/protein kinase B (PKB) pathway, a major mechanism whereby growth factors promote cell survival.4
