Hormones in Recombinant Proteins

Applications An endogenous antidiuretic hormone in most mammalian species. It is released into the blood from nerve terminals in the posterior pituitary and median eminence. It is a neurotransmitter in the central nervous system and also implicated in a variety of physiological processes such as regulating water balance by antidiuretic action. It is a peptidic V1a receptor agonist that produces vasoconstriction via V1aR-mediated vascular smooth muscle cell contraction and is being used to increase blood pressure in septic shock, a form of vasodilatory hypotension.
