WebThyrotropinomas are pituitary adenomas that occur in the thyrotropic cells of the pituitary gland and secrete thyroid-stimulating hormone, or TSH. TSH, in turn, triggers the thyroid … WebTRH-R1 is the predominant receptor in the anterior pituitary gland and has a major regulatory role in stimulating thyrotropin (thyroid-stimulating hormone; TSH) synthesis and secretion and, thereby, plays a central role in thyroid hormone homeostasis. A role for TRH-R1 in regulation of prolactin secretion from the anterior pituitary is less clear.
