Human platelet vasopressin receptors
Life Sciences, 1982Specific saturable binding of 125I-arginine-vasopressin to human platelets is described. For ten normal volunteers the mean (+/- S.D.) KD is 5.6 nM (+/- 2.1) and the mean (+/- S.D.) Bmax is 115 fmoles/mg protein (+/- 30). Association studies indicate that equilibrium is reached after 90 minutes on ice.

Vascular vasopressin receptors
General Pharmacology: The Vascular System, 19881. Vascular vasopressin receptors are understood because of the specific application of each major technical advance in pharmacology; this review shows that isolated organs, whole animal preparations, hormone synthesis, radioligand binding, and human studies have all played their part. 2. Even so, neither vascular vasopressin receptor heterogeneity nor

Vasopressin and vasopressin receptors in brain edema
2020Vasopressin is a peptide hormone produced in the hypothalamus and released from the posterior pituitary. Secretion of vasopressin is followed by activation of its receptors V1a, V1b, and V2 throughout the body. Each receptor type is responsible for a specific function of vasopressin.

Vasopressin Receptor Antagonists
Current Hypertension Reports, 2015Arginine vasopressin (AVP) is the principal hormone involved in regulating the tonicity of body fluids. Less appreciated is the role that AVP plays in a variety of other physiologic functions including glucose metabolism, cardiovascular homeostasis, bone metabolism, and cognitive behavior.

V2 vasopressin receptor mutations
2020V2 vasopressin receptor (V2R) is a member of the G protein-coupled receptor (GPCR) family in which many disease-causing mutations have been identified and thus generated much interest. Loss-of-function V2R mutations cause nephrogenic diabetes insipidus (NDI) whereas gain-of-function mutations cause nephrogenic syndrome of inappropriate antidiuresis ...

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.

Genetics of vasopressin receptors
Current Hypertension Reports, 2004Membrane receptors that couple to guanine nucleotide binding protein (GPCRs) represent one of the largest families of proteins in the genome. Because of their universal distribution and multiple actions, genetic variations of GPCRs are associated with various human diseases.

Vasopressin and oxytocin receptors
Baillière's Clinical Endocrinology and Metabolism, 1996The oxytocin and the vasopressin V1a, V1b and V2 receptors have recently been cloned and shown to form a sub-family within the large superfamily of G-protein-linked receptors. Renal V2 receptors mediate vasopressin-induced water reabsorption via induction of intracellular cAMP production in collecting duct cells.

Human vascular vasopressin receptors: analysis with selective vasopressin receptor antagonists.
The Journal of Pharmacology and Experimental Therapeutics, 1986The vascular activity of arginine vasopressin (AVP) and selective AVP receptor antagonists was investigated in isolated arterial ring segments from human superior mesenteric arteries. AVP elicited a potent and concentration-dependent contraction in human mesenteric arterial rings with an EC50 value of 2.01 X 10(-9) M.

Physiology of the vasopressin receptors
Best Practice & Research Clinical Anaesthesiology, 2008This review article summarizes the structure, signalling pathways, and tissue distribution of the vasopressin receptors, V1 vascular, V2 renal, V3 pituitary, and oxytocin receptors, as well as the P2 class of purinoceptors. The physiological effects of vasopressin on its receptors are described.
