Vasopressin : a potent autocrine/paracrine regulator of mammal adrenal functions.

The control of adrenal functions by locally secreted neuropeptides or neurotransmitters is of great physiological importance. Vasopressin (VP) is one of these autocrine/paracrine regulators. We demonstrated by RT-PCR and perifusion experiments that rat and human adrenal medulla expressed and released vasopressin under basal conditions and under stimulation by acetylcholine.
