The biological effects of arginine vasopressin (AVP) are mediated by three receptor subtypes: the V1a and V1b receptors that activate phospholipases via Gq/11, and the V2 receptor that activates adenylyl cyclase by interacting with Gs. Isolation of the cDNAs encoding the V1a and V1b receptor subtypes explained the tissue variability of V1 antagonist ...

Vasopressin and vasopressin antagonists in heart failure and hyponatremia
Current Heart Failure Reports, 2008Increased synthesis of arginine vasopressin (AVP) plays a critical role in fluid retention and hyponatremia in patients with heart failure. The AVP receptor antagonists constitute a new class of agents that are promising in the management of hyponatremia and congestion.

Vasopressins (VPs) are mammalian VP family nonapeptides. VPs are composed of an intramolecular ring structure flanked by two cysteine residues and a C-terminal extension with a basic amino acid residue at position 8. VP causes antidiuresis, blood pressure elevation, stress response, metabolic actions, and various behaviors through three VP receptors. A

Vasopressin studies in the rat
Pfl�gers Archiv f�r die Gesamte Physiologie des Menschen und der Tiere, 1968A modification of Jeffers method for estimating antidiuretic hormone in body fluids is described. With this modification it is possible to detect antidiuretic activity corresponding to 0.25 μU of Vasopressin.

Renal microvascular effects of vasopressin and vasopressin antagonists
American Journal of Physiology-Renal Physiology, 1989The effects of vasopressin (AVP) and vasopressin antagonists on lumen diameters of cortical afferent and efferent arterioles isolated from rabbit kidneys were examined. Over a concentration range of 10(-14) to 10(-7) M, AVP had no effect on lumen diameters of afferent arterioles, although the arterioles were responsive to norepinephrine.

Vasopressin and Vasopressin Receptor Antagonists in Heart Failure
Cardiology in Review, 2009Antidiuretic hormone, also known as arginine vasopressin, is a hormone with a multitude of physiologic activities including the control of urinary free water excretion. Antidiuretic hormone also plays a role in vasoconstriction and has 3 receptors that have been identified.

Vasopressin metabolites: A link between vasopressin and memory?
1999The effects of endogenous metabolites of the neuropeptide vasopressin (VP) in behavioural tests led to the hypothesis that VP metabolites have a more selective function than VP. In contrast to VP, no peripheral effects have been found thus far with VP metabolites and their function seems to be associated with memory-related behaviour.

Vasopressin in Cardiovascular Control: Role of Circulating Vasopressin
Clinical Science, 1984Vasopressin has been shown to elicit vasoconstriction in unanaesthetized animals at plasma concentrations similar to those associated with its renal antidiuretic effect. The vasconstrictor effects of vasopressin do not normally translate into pressor responses until relatively high plasma concentrations are reached.

Vasopressine et angiogenèse [PDF]
Journal de la Société de Biologie, 2009 In adult mammals, the CNS vasculature remains essentially quiescent, excepted for specific pathologies. In the seventies, it was reported that proliferation of astrocytes and endothelial cells occurs within the hypothalamic magnocellular nuclei when strong metabolic activation of the vasopressinergic and oxytocinergic neurons was induced by prolonged ...

Mechanisms of Vasopressin Secretion
Hormone Research, 1992The magnocellular vasopressin system of the rat has been studied intensively in recent years. This review outlines the electrophysiological characteristics of vasopressin neurons, the characteristics of stimulus-secretion coupling in the neural lobe, and describes some of the major features of the neural regulation of this system which underlie ...
