arginine vasopressin

Also found in: Dictionary, Thesaurus, Acronyms, Encyclopedia.


a hormone secreted by cells of the hypothalamic nuclei and stored in the posterior pituitary for release as necessary; it stimulates contraction of the muscular tissues of the capillaries and arterioles, raising the blood pressure, and increases peristalsis, exerts some influence on the uterus, and influences resorption of water by the kidney tubules, resulting in concentration of urine. Its rate of secretion is regulated chiefly by the osmolarity of the plasma. Also prepared synthetically or obtained from the posterior pituitary of domestic animals; used as an antidiuretic. Called also antidiuretic hormone.
Vasopressin (ADH) regulation. ADH is secreted by the posterior pituitary gland primarily in response to an increase in plasma osmolality. From Malarkey and McMorrow, 2000.
arginine vasopressin vasopressin containing arginine, as that from humans and most other mammals; for medicinal uses, see vasopressin. Called also argipressin.
lysine vasopressin the antidiuretic hormone of the pig family, differing from arginine vasopressin in having lysine instead of arginine at position 8. A synthetic preparation, lypressin, is used as an antidiuretic and vasoconstrictor.

ar·gi·nine va·so·pres·sin (AVP),

vasopressin containing an arginyl residue in position 8 (as in chickens and most mammals, including humans); porcine vasopressin has a lysyl residue at position 8. All are vasopressors.
