Description

Description générale

Research area: Cell Signaling

Thyroid Stimulating Hormone is a glycoprotein produced by anterior pituitary gland. Its structure contains an alpha chain and a beta chain.

Actions biochimiques/physiologiques

Thyroid stimulating hormone It exerts mild, continuous stimulation on the thyroid, resulting in maintenance of activity. TSH modulates the release of T3 and T4 from thyroid follicular cells. Thyroid Stimulating Hormone (TSH) primary targets thyroid gland and maintains thyroid activity. It regulates the release of T3 and T4 hormones from thyroid follicular cells. TSH binds to the TSH receptor (TSHR) and trigger Gs and Gq pathways. Activation of the Gs pathway stimulates iodide uptake, hormone secretion, and gland growth. The Gq pathway is involved in iodide organification for hormone synthesis. TSH secretion is inhibited by Somatostatin. Overexpression of TSH leads to hyperthyroidism, whereas lower TSH expression leads to hypothyroidism.
