CLU and coronary artery disorder: Several characteristics or components of HDL, such as particle size, lipoprotein-associated phospholipase A2 (Lp-PLA2) and paraoxonase activity, apolipoprotein (apo) A-I/apoA-II ratio, and apoC-III and apoJ (also known as clusterin) content [5,8,9,10], are related to these antiatherogenic properties, which are compromised in disorders with high risk for coronary artery disease [10,11].
