Apolipoprotein CIII and atherosclerosis: beyond effects on lipid metabolism.

The prevailing concept of mechanisms responsible for the development of atherosclerotic lesions largely focuses on the accumulation and retention of low-density lipoproteins in the arterial intima and their subsequent oxidative modification. This oxidation leads to activation of the endothelium, and particularly, expression of adhesion molecules that mediate leukocyte adherence and chemokines which initiate the inflammation reaction that is widely accepted as being responsible for the development and progression of atherosclerotic lesions.1,2 There is also a strong body of evidence to indicate that elevated triacylglycerides (triglycerides) are an independent risk factor for atherosclerosis.3–5
