Platelet-activating factor (PAF) is one of the most potent inflammatory mediators. It is biosynthesized by either the de novobiosynthesis of glyceryl ether lipids or by remodeling ofmembranephospholipids. PAFis synthesizedandcatabo-lizedbyvarious renal cells andtissues andexerts awide range of biological activities on renal tissue suggesting a potential role during renal injury. The aimof this studywas to identify whether cortex and medulla of human kidney contain the acetyl-CoA:1-O-alkyl-sn-glycero-3-phosphocholine acetyl-transferase (lyso-PAF AT) activity which catalyses the last step of the remodeling biosynthetic route of PAF and is activated in inflammatory conditions. .
