Vasopressin. Human vasopressin, also called antidiuretic hormone (ADH), arginine vasopressin (AVP) or argipressin, [5] is a hormone synthesized from the AVP gene as a peptide prohormone in neurons in the hypothalamus, [6] and is converted to AVP. It then travels down the axon terminating in the posterior pituitary, and is released from vesicles ...
The arginine vasopressin (AVP) gene is a gene whose product is proteolytically cleaved to produce vasopressin (also known as antidiuretic hormone or ADH), neurophysin II, and a glycoprotein called copeptin. AVP and other AVP-like peptides are found in mammals, as well as mollusks, arthropods, nematodes, and other invertebrate species. [5]
Angiotensin II causes the release of anti-diuretic hormone (ADH), [6] also called vasopressin – ADH is made in the hypothalamus and released from the posterior pituitary gland. As its name suggests, it also exhibits vaso-constrictive properties, but its main course of action is to stimulate reabsorption of water in the kidneys.
However, some of these other substances are known to be important. Dynorphin produced by vasopressin neurons is involved in regulating the phasic discharge patterning of vasopressin neurons, and nitric oxide produced by both neuronal types is a negative-feedback regulator of cell activity. Oxytocin neurons also make dynorphin; in these neurons ...
Vasopressin can be thought of as "water conservation hormone" and is also known as "antidiuretic hormone(ADH)". It is released when the body is dehydrated and has potent water-conserving effects on the kidney. It is also a potent vasoconstrictor. [5] Important to the function of the HPA axis are some of the following feedback loops:
Also called the neural lobe or posterior lobe, this region constitutes the majority of the posterior pituitary and is the storage site of oxytocin and vasopressin. Sometimes (incorrectly) considered synonymous with the posterior pituitary, the pars nervosa includes Herring bodies and pituicytes .
Low pressure receptors. Low pressure baroreceptors or low pressure receptors are baroreceptors that relay information derived from blood pressure within the autonomic nervous system. They are stimulated by stretching of the vessel wall. They are located in large systemic veins and in the walls of the atria of the heart, and pulmonary vasculature.
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.
