Vasopressin

Vasopressin is a cyclic nonapeptide that is synthesized centrally in the hypothalamus. Vasopressin participates in the hypothalamic-pituitary-adrenal axis, and regulates pituitary corticotropin secretion by potentiating the stimulatory effects of corticotropin releasing factor. Vasopressin also can act as a neurotransmitter, exerting its action by binding to specific G protein-coupled receptors.

How to use

In Vitro:

AVP (0.01 nM-1 μM) induces Ca2+ increase in Chinese hamster ovary cells expressing rat or human V1b receptors.

In Vivo:

Vasopressin (0.03-0.3 μg/kg; i.p.) potentiates corticotropin release provoked by exogenous corticoliberin and increases corticotropin secretion subsequent to body water loss. Vasopressin (0.001-0.1 mg/kg; i.p.) potently increases adjacent lying, where rats meeting for the first time lie passively next to each other.
