Application

β-Acetyl-γ-O-hexadecyl-L-α-phosphatidylcholine has been used:
  • to study its effects on phagocytic activity and production of superoxide anion in equine alveolar macrophage and blood neutrophils
  • to study its protective effects against cisplatin-induced cell death in a human melanoma cell line in vitro
  • to determine its effects on cervical ripening and leukocyte infiltration in rat models

Biochem/physiol Actions

β-Acetyl-γ-O-hexadecyl-L-α-phosphatidylcholine or platelet-activating factor (PAF), is a phospholipid, and a pro-inflammatory lipid mediator. It acts as a ligand for G protein-coupled platelet-activating factor (PAF) receptors and participates in several biological processes such as airway constriction, hypotension, platelet activation, and increased vascular permeability. PAF is released by various cells such as platelets, neutrophils, endothelial cells, and monocytes/macrophages. The levels of PAF are low in the blood due to its rapid metabolism by PAF acetylhydrolase and low production.

Alkyl-PAF induced two components of polymorphonuclear leukocyte (PMN) priming for enhanced fMLP- and rC5a-induced superoxide anion (O2-) production. Component A priming had a shallow, linear alkyl-PAF concentration-response slope (10 pM-1 nM), and component B priming had a significantly steeper concentration-response

Platelet-activating factor (PAF) is an early product of the inflammatory environment, influencing development and resolution of inflammation. Its production is greater in neutrophils and macrophages, which predominantly synthesize 1-alkyl sn-2 acetyl glycerophosphocholine (GPC) than in nongranulocytes (B cells and endothelial

Platelet activating factor (PAF, 1-O-alkyl-2-acetyl-sn-glycero-3-phosphocholine) is known to be present in excess in psoriatic skin, but its exact role is uncertain. In the present study we demonstrate for the first time the role of group VI PLA(2) in PAF-induced arachidonic

The purpose of this study was to determine the effect of locally applied platelet-activating factor on cervical ripening and leukocyte infiltration. Timed-pregnant rats were treated vaginally twice each day on days 14 and 15 of gestation with platelet-activating factor 5
