Biochem/physiol Actions

18-carbon analog of platelet activating factor (PAF); ligand for G protein-coupled PAF receptor. It is less potent than PAF C-16 for inducing platelet aggregation, hypotension, bronchosconstriction and chemotaxis, but more potent than PAF C-16 for inducing human neutrophil lysosomal secretion.

Multiple molecular species of platelet activating factor (PAF) are produced as a result of inflammatory processes. PAF-induced neutrophil migration across endothelium is intrinsic to inflammatory responses. We therefore compared the ability of three naturally occurring PAF species (C16:0, C18:0, and

Platelet-activating factor (PAF [1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine]) is a phospholipid mediator released from activated macrophages, mast cells, and basophils that promotes pathophysiologic inflammation. Eosinophil responses to PAF are complex and incompletely elucidated. We show in this article that PAF and its 2-deacetylated metabolite
