Corticotrophin-Releasing Factor Antagonist [alpha helical CRF(9-41)] Blocks Central Noradrenaline-lnduced ACTH Secretion.
Plasma ACTH increased after an intra-third ventricular administration of noradrenaline (NA). An iv corticotrophin-releasing factor (CRF) antagonist [alpha-helical CRF(9-41)] injection did not affect ACTH secretion by itself, whereas it significantly reduced NA-induced ACTH secretion. These results suggest that NA centrally stimulated ACTH secretion and that endogenous CRF is involved in this ACTH secretion.
