Discovery of the previously unknown hormone secretion control mechanism responsible for anxiety in the adrenal cortex [Cell]
A team of researchers headed by Masashi Yanagisawa (Director, International Institute for Integrative Sleep Medicine, WPI-IIIS, University of Tsukuba) revealed in mice studies that the circadian rhythms of glucocorticoid, the stress hormone produced by the adrenal cortex, are controlled by a previously unknown hormone secretion control mechanism that is responsible for anxiety. In addition, the team demonstrated that increased amplitude in the oscillation of circadian glucocorticoid is linked to the action that reduces anxiety in female mice, thus making them braver.
