Platelet-activating factor receptor (version 2019.4) in the IUPHAR/BPS Guide to Pharmacology Database
Platelet-activating factor (PAF, 1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine) is an ether phospholipid mediator associated with platelet coagulation, but also subserves inflammatory roles. The PAF receptor (provisional nomenclature recommended by NC-IUPHAR ) is activated by PAF and other suggested endogenous ligands are oxidized phosphatidylcholine  and lysophosphatidylcholine . It may also be activated by bacterial lipopolysaccharide .
