Role of LCAT activity changes in atherosclerosis risk

D. A. Dorovsky, A. L. Zagayko

Abstract


Lecithin cholesterol acyltransferase (LCAT) is a key enzyme that catalyzes the esterification of free cholesterol in plasma lipoproteins and plays a critical role in high density lipoprotein (HDL) metabolism. LCAT deficiency  leads to accumulation of nascent pre-HDL due to impaired maturation of HDL particles, whereas enhanced expression is associated with the formation of   large, apoE-rich HDL 1 particles. In addition to its function in HDL metabolism, LCAT was believed to be an important driving force behind macrophage reverse cholesterol transport (RCT) and, therefore, has been a subject of great interest in cardiovascular research since its discovery in 1962. Although half a century has passed, the importance of LCAT for atheroprotection is still under intense debate.
