“…we report for the first time the expression of CB1 in the human pituitary gland and human pituitary adenomas… cannabinoid-induced modulation of hormonal release were shown… these results indicate a potentially important role of the endocannabinoid system in pituitary pathophysiology, thus opening new perspectives in the management of pituitary adenomas… The results of this study point to a direct role of cannabinoids in the regulation of human pituitary hormone secretion.”
