title: Effect of angiotensin II on ACTH release in vivo: role of corticotropin-releasing factor.
abstract: The ability of angiotensin II (ANG II) to release ACTH was studied in vivo. ANG II elicited dose-related increases in plasma ACTH levels in freely-moving non-anesthetized rats. The observation that this effect was totally abolished by immunoneutralization of endogenous CRF, as well as the lack of stimulatory activity of ANG II in pharmacologically blocked animals, suggest that the induction of CRF secretion by ANG II represents an essential modulator of the ACTH-releasing potency of this peptide.
