Sphingolipids such as ceramide and sphingomyelin (SM) are the major components of the plasma membrane and supply the place for the ligand-receptor association regulating numerous cellular functions including proliferation, migration, cell death, inflammation, and autophagy. On the other hand, it is well-known that intracellular ceramide, which is hydrolyzed from SM, acts as the bioactive lipid inducing apoptosis or autophagy. We aim to elucidate the roles of sphingolipids in these cellular functions and their molecular mechanisms by using cells and animal models. In the future, we hope that sphingolipids and their metabolisms become the clinical and therapeutic targets for various diseases such as cancer, virus infection, and inflammation.
