  • Title: [Natriuretic peptides--their receptors and role in cardiovascular system].
    Author: Jerczyńska H, Pawłowska Z.
    Journal: Postepy Biochem; 2008; 54(1):35-42. PubMed ID: 18610580.
    Abstract:
    Natriuretic peptides belong to a family of small proteins that play a major role in modulation of natriuresis, diuresis and vasodilatation. They counteract the activity of renin-angiotensin-aldosterone system. They are also involved in the regulation of homeostasis, fat metabolism and long bone growth. Natriuretic peptides family in mammals consists of three main members: atrial natriuretic peptide (ANP) - secreted by the atrial myocardium; brain natriuretic peptide (BNP)--secreted mainly by the ventricular myocardium, and C-type natriuretic peptide (CNP)--produced and released by endothelial cells. Secretion of these peptides is stimulated by atrial and ventricular distension, increased blood pressure, hypoxia or renal dysfunction. Natriuretic peptides play their roles via interactions with NPR-A and NPR-B receptors which are transmembrane guanylyl cyclases. Their local concentrations, regulated by internalization and degradation, are mediated by the NPR-C receptor and by neutral endopeptidase. The paper presents the current knowledge of structure and biological function of natriuretic peptides.
