Lipoprotein-associated phospholipase A2 (Lp-PLA2) also known as platelet-activating factor acetylhydrolase (PAF-AH) is a phospholipase A2 enzyme that in humans is encoded by the PLA2G7 gene.[1][2] Lp-PLA2 is a 45kD protein of 441 amino acids.[3] It is one of several PAF acetylhydrolases.
In the blood it travels mainly with low-density lipoprotein (LDL).
Less than 20% is associated with high-density lipoprotein HDL.
It is an enzyme produced by inflammatory cells and hydrolyzes oxidized phospholipids in LDL.
Lp-PLA2 is platelet-activating factor (PAF) acetylhydrolase (EC 3.1.1.47), a secreted enzyme that catalyzes the degradation of PAF to inactive products by hydrolysis of the acetyl group at the sn-2 position, producing the biologically inactive products LYSO-PAF and acetate.[4] Lp-PLA2 is involved in the development of atherosclerosis,[3] an observation that has prompted interest as a possible therapeutic target (see, e.g.
the investigational drug Darapladib).
In human atherosclerotic lesions, 2 main sources of Lp-PLA2 can be identified, including that which is brought into the intima bound to LDL (from the circulation), and that which is synthesized de novo by plaque inflammatory cells (macrophages, T cells, mast cells).
