Natriuretic peptide system consists of three endogenous ligands, ANP (atrial natriuretic peptide), BNP (brain natriuretic peptide) and CNP (C-type natriuretic peptide), and three receptor subtypes, natriuretic peptide receptor (NPR)-A or guanylate cyclase (GC)-A and NPR-B or GC-B and C receptor (NPR-C). ANP and BNP are mainly secreted from the atrium and ventricle of the heart respectively to act as cardiac hormones whereas CNP is secreted from the endothelium to act as an endothelium-derived relaxing peptide. ANP and BNP regulate body fluid and blood pressure to reduce cardiac pre- and after-load. Recent molecular biology and developmental biotechnology demonstrated the physiological role of ANP and BNP for the determination of basal blood pressure. CNP can modulate the phenotype of vascular smooth muscle cells to regulate vascular remodeling. Therefore, natriuretic peptide system is implicated in the pathophysiology of hypertension, congestive heart failure atherosclerosis and renal diseases. Clinical application of natriuretic peptide system is actively going on progress. Determination of plasma ANP and BNP levels are useful for the evaluation of congestive heart failure, cardiac hypertrophy and acute myocardial infarction. Infusion of ANP improves acute heart failure. Application of NEP (neutral endopeptidase) inhibitor for the treatment of congestive heart failure and hypertension is under clinical trial.
