these unequivocal effects on energy metabolism, 3,5-T2 might also affect the hypothalamus–pituitary–thyroid axis. Horst et al . (1995) have shown that 3,5-T2 treatment reduced serum thyroid-stimulating hormone (TSH) and thyroxine (T 4 ) levels as well

The TSH receptor and its role in the thyroid The established biological function of the TSH receptor (TSHR) in the thyroid gland is to regulate synthesis and secretion of thyroid hormones from follicular thyroid cells; it also plays an important

uncleaved holoreceptors on the cell surface than seen in thyroid cells ( Misrahi et al. 1994 , Rapoport et al. 1998 ). Deletion of the cleaved region in the TSHR ectodomain does not affect TSH binding to, nor activation of, the TSHR ( Chazenbalk et al

Introduction The thyrotrophin receptor (TSH-R) belongs to the family of G protein-coupled receptors (GPCRs) containing seven transmembrane helices (TMH). Since 1994, activating germline mutations of the TSH-R have been identified as

Introduction The feedback regulation of TSH secretion by thyroid hormones is mediated by the binding of 3,3′,5′-triiodothyronine (T 3 ) to the TRβ2 receptor in the pituitary and hypothalamus ( Chiamolera & Wondisford 2009 ). The acute suppression of

Introduction The TSH receptor or the thyrotropin receptor (TSHR) is usually expressed by thyroid cells. It is a G protein-coupled receptor and signals through cAMP and inositol triphosphate (IP 3 ) pathways ( Kursawe & Paschke 2000 , Davies et al
