Thyrotropin releasing hormone

Thyrotropin-releasing hormone (TRH) is a tripeptide secreted by the hypothalamus. Its physiological function is to release TSH stored in anterior pituitary cells through a series of pathways, and TSH and T3 and T4 levels in blood. Increase. The THR, T3, and T4 are measured at the same time as the plasma TRH is measured, so that you can understand the cause of thyroid lesions, whether the lesions occur in the thyroid or the pituitary or hypothalamus. TRH has been successfully synthesized by humans and has been used clinically.
