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.
Selective vasopressin V2 antagonist (sometimes called aquaretics) tolvaptan , [ 15 ] conivaptan Competitive vasopressin antagonism leads to decreased number of aquaporin channels in the apical membrane of the renal collecting ducts in kidneys, causing decreased water reabsorption.
The collecting duct system of the kidney consists of a series of tubules and ducts that physically connect nephrons to a minor calyx or directly to the renal pelvis.The collecting duct participates in electrolyte and fluid balance through reabsorption and excretion, processes regulated by the hormones aldosterone and vasopressin (antidiuretic hormone).
The relationship between natriuretic peptides and vasopressin, a hormone that regulates water balance, has been found through studies that have shown that ANP can suppress vasopressin signaling. Researchers are working on having a better understanding of this relationship.

When it is needed, vasopressin binds to the cell surface vasopressin receptor thereby activating a signaling pathway that causes the aquaporin 2 containing vesicles to fuse with the plasma membrane, so the aquaporin 2 can be used by the cell. [6] This aquaporin is regulated in two ways by the peptide hormone vasopressin:
Vasopressin (antidiuretic hormone) ADH or AVP or VP: Parvocellular neurosecretory neurons, Magnocellular neurosecretory neurons of the Paraventricular nucleus and Supraoptic nucleus: Increases water permeability in the distal convoluted tubule and collecting duct of nephrons, thus promoting water reabsorption and increasing blood volume
