AVP deficient Brattleboro rats have a blunted corticosterone response to some but not all stressors [156,157], while elegant studies using immuno-neutralization of AVP also reported a blunted HPA response to a range of stressors including restraint, insulin-induced hypoglycemia and lipopolysaccharide [[158], [159], [160]]. Here, AVP is linked to Hypoglycemia.
