Signal transduction by HDL: agonists, receptors, and signaling cascades.
Münster, Germany. In Handb Exp Pharmacol, 2014
Several HDL-associated receptor ligands such as apolipoprotein A-I (apoA-I) or sphingosine-1-phosphate (S1P) have been identified in addition to HDL holoparticles, which interact with surface receptors such as ATP-binding cassette transporter A1 (ABCA1); S1P receptor types 1, 2, and 3 (S1P1, S1P2, and S1P3); or scavenger receptor type I (SR-BI) and activate intracellular signaling cascades encompassing kinases, phospholipases, trimeric and small G-proteins, and cytoskeletal proteins such as actin or junctional protein such as connexin43.
Sphingolipids in acute lung injury.
Aachen, Germany. In Handb Exp Pharmacol, 2012
Sphingolipids are critically involved in the disease process that they can both expedite and extenuate: They expedite inflammation by promoting chemotaxis (neutral sphingomyelinase), increased endothelial permeability (acid sphingomyelinase, S1P3-receptors), increased epithelial permeability (S1P2- and S1P3-receptors), and delaying neutrophil apoptosis (neutral sphingomyelinase, S1P1-receptors).

Identification of a Novel Agonist of the Sphingosine 1-phosphate Receptor 4 (S1P4)
Bethesda, United States. In Unknown Journal, 0001
ML248 activates S1P4 receptor with a half maximal effective concentration (EC50) of 37.7 nM–79.1 nM, and is inactive as an agonist against other members of the receptor family, with EC50s > 25 μM against S1P1, S1P2, and S1P3 receptors, and an EC50 of 2.1 μM against the S1P5 receptor.
