TRH

Meaning

TRH is the abbreviation for Thyrotropin-Releasing Hormone, a small tripeptide neurohormone synthesized primarily by neurosecretory cells in the hypothalamus. It is recognized as the central regulatory signal that initiates the entire cascade of the hypothalamic-pituitary-thyroid (HPT) axis. TRH plays a crucial role in maintaining the body’s metabolic rate, temperature regulation, and overall energy homeostasis by controlling thyroid hormone production.
