The actions of vasopressin are mediated by stimulation of tissue-specific G protein-coupled receptors (GPCRs) called vasopressin receptors that are classified into the V 1 (V 1A), V 2, and V 3 (V 1B) receptor subtypes. [1] These three subtypes differ in localization, function and signal transduction mechanisms. [2]
Vasopressin infusions are in use for septic shock patients not responding to fluid resuscitation or infusions of catecholamines (e.g., dopamine or norepinephrine) to increase the blood pressure while sparing the use of catecholamines. These argipressins have much shorter elimination half-life (around 20 minutes) than synthetic non-arginine ...
Atrial volume receptors (also known as Veno-atrial stretch receptors [1]) are low pressure baroreceptors that are found in the atria of the heart. They are myelinated vagal fibres in the endocardium found at the junction between atria and the vena cava/pulmonary vein.
Researchers are working on having a better understanding of this relationship. Animal studies show the possibility of using a vasopressin receptor antagonist along with BNP to improve heart function and blood flow.

The functions of vasopressin make it useful for a variety of important medical applications. Since it plays a role in the regulation of many physiological functions, like regulation of water and sodium excretion, blood volume, vasoconstriction , and response to stress , vasopressin can be helpful in the treatment of conditions related to these ...
An osmoreceptor is a sensory receptor primarily found in the hypothalamus of most homeothermic organisms that detects changes in osmotic pressure.Osmoreceptors can be found in several structures, including two of the circumventricular organs – the vascular organ of the lamina terminalis, and the subfornical organ.
Its activity is mediated by G proteins which stimulate a phosphatidylinositol-calcium second messenger system. It is a major contributor to homeostasis and the control of water, glucose, and salts in the blood. Arginine vasopressin has four receptors, each of which are located in different tissues and have specific functions.
