vasopressin

 [vas″o-pres´in]
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.

va·so·pres·sin (VP),

(vā'sō-pres'in, vas-ō-),
A nonapeptide neurohypophysial hormone related to oxytocin and vasotocin; synthetically prepared or obtained from the posterior lobe of the pituitary of healthy domestic animals. In pharmacologic doses vasopressin causes water retention and contraction of smooth muscle, notably that of all blood vessels; large doses may produce cerebral or coronary arterial spasm.

(vā′zō-prĕs′ĭn)
n.
A hormone secreted by the posterior lobe of the pituitary gland that constricts blood vessels, raises blood pressure, and reduces excretion of urine. Also called antidiuretic hormone.

A nonapeptide neurohypophysial hormone related to oxytocin and vasotocin; synthetically prepared or obtained from the posterior lobe of the pituitary of healthy domestic animals. In pharmacologic doses, vasopressin causes contraction of smooth muscle, notably that of all blood vessels; large doses may produce cerebral or coronary arterial spasm.

vasopressin

A hormone secreted in the HYPOTHALAMUS and stored in and released from the PITUITARY GLAND. Vasopressin controls water retention by the kidneys and thus the water content of the body. Deficiency of vasopressin causes DIABETES INSIPIDUS.

Antidiuretic hormone (vasopressin)

A hormone that acts on the kidneys to regulate water balance.

Although the new study is purely observational and does not prove causality, the researchers think that the hormone vasopressin may be responsible for the link between too little sleep and a lack of hydration.
The cause was linked to the way the body's vasopressin a hormone is released to help regulate the body's hydration status throughout the day, as well as during night-time sleeping hours.
"Vasopressin is released both more quickly and later on in the sleep cycle," said lead author Asher Rosinger.
