Clinical potentials of neuropeptide Y family of hormones

Neuropeptide Y (NPY) family of hormones exhibits a wide spectrum of central and peripheral activities mediated by six G-protein coupled receptor subtypes denoted as Y1, Y2, Y3, Y4, Y5, and y6. Investigations to date have implicated NPY in the pathophysiology of a number of diseases including feeding disorders, seizures, anxiety, diabetes, hypertension, congestive heart failure and intestinal disorders. These observations suggest that long-acting, potent NPY receptor selective agonists and antagonists developed could be used to treat a variety of diseases. These possibilities are discussed in this paper.
