In the presented study, we demonstrate that the interaction of group IVA cytosolic phospholipase A2 and ceramide-1-phosphate is crucial for production of eicosanoid synthesis in inflammation. Inflammation is a critical component of many disease states including anaphylaxis, cancer, cardiovascular disease, rheumatoid arthritis, diabetes and asthma. Eicosanoids are well established mediators of inflammation, and the initial rate limiting step in the production of eicosanoids is the liberation of arachidonic acid (AA) from membrane phospholipids by a phospholipase A2 (PLA2). The major phospholipase involved in this liberation of AA during the inflammatory response is group IVA cytosolic phospholipase A2 (cPLA2α). Previous studies …
