Evidence that N-acetylation regulates the behavioral activity of alpha-MSH in the rat and human central nervous system.

abstract：:Arginine-vasopressin (AVP) is a hypothalamic hormone that, like CRH, stimulates the pituitary release of ACTH, thereby activating adrenal glucocorticoid secretion. Evidence indicates that rat adrenal medulla contains a CRH-ACTH system duplicating that existing at the hypothalamo-pituitary level and involved in the par...
