Flak J, Myers B, Solomon M, McKlveen J, Krause E, Herman J (2014) Role of paraventricular nucleus-projecting norepinephrine/epinephrine neurons in acute and chronic stress. Eur J Neurosci 39:1903-1911. doi: 10.1111/ejn.12587
Summary: Chronic stress can cause dysregulation of the paraventricular nucleus (PVN) of the hypothalamus, resulting in structural and function changes in the neurons involved. There are data indicating that post-stress enhancement of norepinephrine is involved in the processing of chronic stress. In this work the authors investigated the hypothesis that PVN-projecting norepinephrine/epinephrine (NE/E) neurons are necessary for chronic stress-induced drive of the hypothalamic-pituitary-adrenocortical (HPA) axis. Rats received bilateral 8.82 ng injections of anti-DBH-SAP (Cat. #IT-03) into the PVN. Saporin (Cat. #PR-01) was used as a control. Lesioned animals displayed attenuated peak ACTH, indicating that NE/E neurons are required for ACTH release in the HPA axis during chronic stress.
