Ontogeny of the stress response in the rat: role of the pituitary and the hypothalamus

CD WALKER, M PERRIN, W VALE, C RIVIER - Endocrinology, 1986 - academic.oup.com

Endotoxin and the hypothalamo-pituitary-adrenal (HPA) axis

A Beishuizen, LG Thijs - Journal of endotoxin research, 2003 - journals.sagepub.com
Endotoxin is considered to be a systemic (immunological) stressor eliciting a prolonged
