  • Look Inside

Atrial natriuretic peptide (ANP) is a peptide hormone first isolated from the cardiac atrium and possesses potent diuretic, natriuretic and vasorelaxant activities. The discovery of ANP cast light upon the heart as an endocrine organ involved in the control of blood pressure and body fluid. Soon after the discovery of this peptide in the heart, the investigation using radioimmunoassay (RIA) and immunohistochemistry revealed the existence of ANP in the central nervous system (CNS) and suggested the implication of this peptide in the central regulation of cardiovascular homeostasis as a neurotransmitter or neuromodulator. Following the identification of ANP in CNS, new members of natriuretic peptides were isolated from the brain. Brain natriuretic peptide (BNP), which was originally isolated from the porcine brain, is now known to be produced predominantly in the cardiac ventricle and act as a hormone. The other homologue of ANP, C-type natriuretic peptide (CNP), was first isolated from the porcine brain, is now known to act as a neuropeptide or a local modulator, since CNP exists relatively in high concentrations in the brain, whereas it is so far undetectable in the heart.
