Target intelligence / Profile preview

Lipoprotein-associated Phospholipase A2 (Lp-PLA2)

Target
Lp-PLA2
Molecular classification
Enzyme, Phospholipase A2 superfamily, Hydrolase
01

Overview

Lipoprotein-associated phospholipase A2 (Lp-PLA2) is a secreted enzyme that hydrolyzes oxidized phospholipids and platelet activating factor (PAF), generating pro-inflammatory mediators. Primarily produced by inflammatory cells and transported by LDL and HDL, Lp-PLA2 is associated with increased risk for cardiovascular diseases and serves as a potential therapeutic target for vascular inflammation and atherosclerosis. Unlike general inflammatory markers, Lp-PLA2 is a vascular-specific biomarker.
