Abstract:
*NO is produced endogenously from L-arginine by NOSs. Among its multiple activities, the homeostatic control of the vascular endothelium is crucial for atherosclerosis, a pathogenic condition connected with elevated levels of LDL, the main plasma cholesterol carrier. Oxidised LDL is proatheromatic, and toxic peroxidation products contribute to further endothelial damage. *NO controls vascular tone, inhibits LDL oxidation and has hypocholesterolaemic activity. This review is referred to the chemistry, biology and role of *NO on atherosclerosis and its treatment by *NO donors or modulators.
