Neuropeptide Y (NPY) plays a vital role in feeding behaviour, anxiety, epilepsy, circadian, rhythm memory processing, sleep, pain and drug addiction. In addition, it is also implicated in regulation of appetite, body weight and obesity. It controls central endocrine secretion and has potent vasoactive effects on the cardiovascular system. NPY is involved in the pathogenesis of atherosclerosis and coronary artery disease.
