Abstract

Cell signaling is accompanied by rapid remodeling of membrane lipids by activated phospholipases (PLA2, PLC, PLD and sphingomyelinase) with the generation of bioactive lipids that can serve as intra- and/or extracellular mediators (Serhan, et al., 1996). These lipid mediators include eicosanoids, platelet activating factor (PAF), diacyl glycerides, lyso-phosphatidylcholine (LPC), phosphatidic acid (PA), lyso-PA, ceramide and other newly-discovered autacoids. They are important in a wide range of cell-cell communication processes, such as host defense, inflammation, ischemia reperfusion and homeostasis.
