Relaxes vascular smooth muscle in arterioles and venules by:. Steroidogenesis, especially mineralocorticoid synthesis, is inhibited by ANP, but glucocorticoid production seems to be depressed too.

The hypothalamo-hypophyseal axis is another important target. ANP acts on the kidney to increase sodium and water excretion natriuresis in the following ways: ANP in one of a family of cardiac NP’s: A synthetic form has been produced.

Beside these four, five additional natriuretic peptides have been identified: They are all cell surface receptors and designated:. Secretion clearance Pharmacokinetics Clearance of medications Urine flow rate. A version of this article was updated by an external expert under a dual publication model.

Atrial natriuretic peptide ANP or atrial natriuretic factor ANF is facfor natriuretic peptide hormone secreted from the cardiac atria. Binding of a natriuretic peptide induces a conformational change in the receptor that causes receptor dimerization and activation.


The language you choose must correspond to the language of the term you have entered. Available structures PDB Ortholog search: Its main targets are the kidney and the cardiovascular system but ANP interacts with many other hormones in order to regulate their secretion.

[Atrial natriuretic hormone and endocrine functions].

Expert Opinion on Therapeutic Patents. Reduction of blood volume by ANP can result in secondary effects such as reduction of extracellular fluid ECF volume edemaimproved cardiac ejection fraction with resultant improved organ perfusion, decreased blood pressureand increased serum potassium. Several inhibitors of NEP are currently being developed to treat disorders ranging from hypertension to heart failure.

The adrenal glands are the first endocrine target. auricula

NP’s are made in cardiac, intestinal, renal, and adrenal tissue: A salmon natriuretic peptide known as salmon cardiac peptide has been described, [33] and dendroaspis natriuretic peptide DNP has been found in the venom of the green mambaas well as an NP in a species of African snake. Vander’s Human Physiology 11th ed.

Its main function is to lower blood pressure and to control electrolyte homeostasis. It acts via atrial natriuretic peptide receptors but with fold lower affinity than ANP. Opinions regarding the use of ANP for the treatment of acute heart failure and kidney disease are varied.


There are three volume regulating systems: Large amounts of ANP secretion has been noted to cause aruicular disturbances hyponatremia and polyuria.

Chromosome 1 human [1]. Maintenance of the ECF volume spaceand its subcompartment the vascular space, is crucial for survival.

Glossaries and vocabularies Access Translation Bureau glossaries and vocabularies. The ring is formed by a disulfide bond between two cysteine residues at positions 7 and Language Portal of Canada Access a collection of Canadian resources on all aspects of English and French, including quizzes. Plasma ANP levels are impaired facto several endocrine diseases: Renal blood flow Ultrafiltration Countercurrent exchange Filtration fraction.

Because of a local production, ANP may also act as a paracrine hormone that influences the function of many endocrine systems ovarian function for instance. Glucagon Insulin Amylin Somatostatin Pancreatic polypeptide.

ANP is synthesized, and secreted by cardiac muscle cells in the walls of the atria in the heart. The discovery of ANP was reported inwhen rat atrial extracts were found to contain a substance that increased salt and urine output in the kidney.
