  • Title: Discovery of a natriuretic peptide family and their clinical application.
    Author: Matsuo H.
    Journal: Can J Physiol Pharmacol; 2001 Aug; 79(8):736-40. PubMed ID: 11558683.
    Abstract:
    The identification of atrial natriuretic peptide (ANP) induced an explosive series of studies on the new peptide involved in control of the circulation, both in the basic and clinical fields. During the first decade of ANP research surprising progress has been made, revealing that the heart is an endocrine organ regulating the circulation system. ANP has been developed as a diagnostic tool and as a therapeutic drug for cardiac failure. In the second decade, brain natriuretic peptide (BNP) and C-type natriuretic peptide (CNP) were identified, unveiling new profiles of this peptide family. Although BNP is also a circulating hormone that shares a common receptor with ANP, it is different from ANP in its' synthesis and secretion. Plasma concentration of BNP reflects the severity of heart failure in patients in a dramatic fashion, much moreso than ANP. Thus, BNP has been developed as a powerful diagnostic tool for cardiovascular diseases. The third congener, CNP, having a receptor of its own, was initially thought to function only in the brain. CNP was subsequently found to be produced from vascular endothelial cells and macrophages, indicating that CNP is a local regulator and also an antiproliferative factor in the vascular cell system, rather than a circulating hormone. Trials for the clinical application of CNP have also been discussed.
