Introduction to Protirelin
- Protirelin, also known as thyrotropin-releasing hormone (TRH), induces the secretion of thyroid-stimulating hormone (TSH) from the anterior pituitary gland.
- This tripeptide tropic hormone, synthesized and released by the hypothalamus, is critical in stimulating the anterior pituitary to release both thyroid-stimulating hormone (TSH) and prolactin. Additionally, protirelin shows prolactin-releasing activity.
