The Brattleboro rat is a strain of laboratory rat descended from a litter born in West Brattleboro, Vermont in 1961 without the ability to produce the hormone vasopressin, which helps control kidney function. The rats' lack of vasopressin was the result of a naturally occurring genetic mutation. [citation needed]
The willingness of the female rats to access males was considered a direct measure of the females' levels of sexual motivation. An increase in vasopressin has been observed in female rats which have just given birth. Vasopressin is associated with aggressive and hostile behaviours, and is postulated to decrease sexual motivation in females.
Loss of an affected limb is possible even with prompt treatment. Haemotoxins are frequently employed by venomous animals, including snakes ( vipers and pit vipers ) and spiders ( brown recluse ). Animal venoms contain enzymes and other proteins that are haemotoxic or neurotoxic or occasionally both (as in the Mojave rattlesnake , the Japanese ...
The vasopressin-like peptides, which differ in positions 3 and/or 8, include AVT and the mammalian hormones arginine vasopressin (Cys-Tyr-Phe-Gln-Asn-Cys-Pro-Arg-Gly-NH2, with isoleucine-3 of AVT changed to phenylalanine) and lysine vasopressin (isoleucine-3 changed to phenylalanine and arginine-8 changed to lysine).

Vasopressin is used to manage anti-diuretic hormone deficiency. Vasopressin is used to treat diabetes insipidus related to low levels of antidiuretic hormone. It is available as Pressyn. [53] Vasopressin has off-label uses and is used in the treatment of vasodilatory shock, gastrointestinal bleeding, ventricular tachycardia and ventricular ...
Vasopressin receptor 1A (V1AR), or arginine vasopressin receptor 1A (officially called AVPR1A) is one of the three major receptor types for vasopressin (AVPR1B and AVPR2 being the others), and is present throughout the brain, as well as in the periphery in the liver, kidney, and vasculature. [5] AVPR1A is also known as: V1a vasopressin receptor
The well known antidiuretic effect of vasopressin occurs via activation of V 2 R. [1] Vasopressin regulates water excretion from the kidney by increasing the osmotic water permeability of the renal collecting duct – an effect that is explained by coupling of the V 2 R with the G s signaling pathway, which activates cAMP.
