TRH, commonly known as Protirelin, is a petite hormone produced within the hypothalamus. Its primary roles involve triggering the release of thyroid-stimulating hormone and prolactin from the anterior pituitary. In clinical settings, TRH is employed to evaluate the anterior pituitary gland’s function in diagnosing thyroid disorders. Studies suggest TRH possesses antidepressant and anti-suicidal attributes and potentially contributes to regulating various aspects including the aging process, arousal, feeding behavior, autonomic regulation, and combating free radical damage.
