Members of the family of Lysophospholipid receptors are GPCRs (GPCR-A13) that are important for lipid signaling[1]. Their endogenous ligands encompass lysophosphatidic acid (LPA) and sphingosine 1-phosphate (S1P). The principal effects of LPA and S1P are growth related, including induction of cellular proliferation, alterations in differentiation and survival, and suppression of apoptosis. LPA and S1P also evoke cellular effector functions, which are dependent on cytoskeletal responses such as contraction, secretion, adhesion, and chemotaxis[2],[3]. The classical S1PR1 ligand Fingolimod (FTY 720, Axon 1485) is known for its characteristics as an immunomodulating drug, approved for treating multiple sclerosis. Interestingly, recent studies indicated the ligand could also be a candidate therapeutic drug for the treatment of heart failure and arrhythmias by activation of the P21-activated kinase-1 (Pak1)[4].
