Phospholipid produced by lymphocytes, platelets and endothelial cells that induces platelet aggregation and is involved in inflammation, anaphylaxis and wound repair.
Platelet-activating factor (1-0-alkyl-2-acetyl-sn-glyceryl-3-phosphorylcholine, PAF) is a potent inducer of shape-change, aggregation and secretion in platelets. PAF causes a rapid increase in intracellular calcium, but has no calcium gating effect in intact lipid bilayers. Human red cells (RBC) did not metabolize

Mast cells are the major effector cells in immunoglobulin E (IgE)-mediated allergy. The high affinity IgE receptor FcεRI, as well as G protein-coupled receptors (GPCRs) on the mast cell surface signals to phosphoinositide 3-kinase γ (PI3Kγ) to initiate degranulation, cytokine

Neutrophils play a central role in immunity and inflammation via their intrinsic ability to migrate into inflamed tissue, to phagocytose pathogens, and to kill bacterial and fungi by releasing large quantities of superoxide anions and lytic enzymes. The molecular pathways
