Abstract
The lysophospholipids, lysophosphatidic acid (LPA) and sphingosine 1-phosphate (S1P), regulate various signaling pathways within cells by binding to multiple G protein-coupled receptors. Receptor-mediated LPA and S1P signaling induces diverse cellular responses including proliferation, adhesion, migration, morphogenesis, differentiation and survival. This review will focus on major components of lysophospholipid signaling: metabolism, identification and expression of LPA and S1P receptors, general signaling pathways and specific signaling mechanisms in mouse embryonic fibroblasts. Finally, in vivo effects of LP receptor gene deletion in mice will be discussed.
