Natriuretic peptides are a family of structurally related but genetically distinct hormones/paracrine factors that regulate blood volume, blood pressure, ventricular hypertrophy, pulmonary hypertension, fat metabolism, and long bone growth. The mammalian members are atrial natriuretic peptide, B-type natriuretic peptide, C-type natriuretic peptide, and possibly osteocrin/musclin. Three single membrane-spanning natriuretic peptide receptors (NPRs) have been identified. Two, NPR-A/GC-A/NPR1 and NPR-B/GC-B/NPR2, are transmembrane guanylyl cyclases, enzymes that catalyze the synthesis of cGMP. One, NPR-C/NPR3, lacks intrinsic enzymatic activity and controls the local concentrations of natriuretic peptides through constitutive receptor-mediated internalization and degradation. Single allele-inactivating mutations in the promoter of human NPR-A are associated with hypertension and heart failure, whereas homozygous inactivating mutations in human NPR-B cause a form of short-limbed dwarfism known as acromesomelic dysplasia type Maroteaux. The physiological effects of natriuretic peptides are elicited through three classes of cGMP binding proteins: cGMP-dependent protein kinases, cGMP-regulated phosphodiesterases, and cyclic nucleotide-gated ion channels. In this comprehensive review, the structure, function, regulation, and biological consequences of natriuretic peptides and their associated signaling proteins are described.

Natriuretic peptides are peptide hormones which are involved in the regulation of blood pressure, water-mineral balance and multiple metabolic processes. The beginning of research on this group of hormones starts in 1981, when the deBold and collaborators discovered ANP. Eight natriuretic peptides have been described so far: ANP, BNP, CNP, DNP, urodilatin, uroguanylin, osteocrin, musculin and three receptors: NPR-A, NPR-B and NPR-C thanks to which these hormones accomplish their physiological functions. Determination of natriuretic peptide concentration in plasma is used in the diagnosis and treatment of heart failure and pulmonary embolism. Research results indicate that the determination of natriuretic peptides concentration in plasma may also be important in the acute coronary syndromes, subclinical complications of hypertension and atrial fibrillation. The concentration of natriuretic peptides is changing in many diseases. The beneficial effects of natriuretic peptides have led to the production of drugs that are their synthetic derivatives. These drugs are mainly used among patients with heart failure. Research is currently underway on the efficacy and safety of other synthetic natriuretic peptides.
