...Edwards Shalts; Linna Xia; Ennian Xiao; Michel Ferin Arginine-vasopressin (AVP) has been previously shown to act in synergism with corticotropin-releasing hormone (CRH) in mediating stress-induced changes in the hypothalamo-pituitary-adrenal (HPA) axis. We have previously shown that both AVP...

... arginine-vasopressin (AVP) increased 7 and 14 days after ADX. MBH CRF decreased after ADX, but returned to sham value 2 weeks later; similarly, MBH AVP decreased at all periods after ADX. Removal of endogenous glucocorticoids did not vary neither oxytocin (OXY) content in the ME and MBH nor AVP and OXY...
