Platelet-activating Factor Receptor (PAFR)

The platelet-activating factor receptor (PAFR) is a G-protein-coupled receptor involved in both normal physiological and numerous pathophysiological processes. PAFR responds to platelet-activating factor (PAF), a phospholipid mediator of cell-to-cell communication that exhibits diverse physiological effects. Stimulation of the PAFR via binding of platelet-activating factor (PAF) elicits diverse and potent biological activities and plays a profound role in acute inflammation, allergic disorders, endotoxic shock, and anaphylaxis. PAF is a potent and versatile mediator of inflammation that is produced by numerous cell types and tissues, and particularly by leukocytes.
