Vasopressin also increases the concentration of calcium in the collecting duct cells, by episodic release from intracellular stores. Vasopressin, acting through cAMP, also increases transcription of the aquaporin-2 gene, thus increasing the total number of aquaporin-2 molecules in collecting duct cells. [16]

Vasopressin agonists are used therapeutically in various conditions, and its long-acting synthetic analogue desmopressin is used in conditions featuring low vasopressin secretion, as well as for control of bleeding (in some forms of von Willebrand disease and in mild haemophilia A) and in extreme cases of bedwetting by children.
“This low circulating blood volume causes the release of the hormone vasopressin and when in high enough concentrations, vasopressin constricts blood vessels and causes higher blood pressure ...
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]

However, the release of oxytocin and vasopressin from dendrites is not consistently accompanied by peripheral secretion, as dendritic release is regulated differently. Dendritic release can be triggered by depolarisation, but can also be triggered by the mobilisation of intracellular calcium stores.
Kidneys are important for regulating blood pressure and filtering waste products from the bloodstream; managing urine excretion to prevent dehydration; and regulating levels of electrolytes and ...
