Tsh binding
WebDuring the hypothyroid phase, TSH-binding inhibitory immunoglobulins (TBII) could not be detected, while thyroid stimulating antibodies (TSAb) were positive showing between 5.8 and 90 fold increases in the amount of cAMP produced in cultured porcine thyroid cells. Her IgG did not inhibit TSH-induced cAMP increase in vitro. WebFeb 1, 2004 · However, upon TSH binding there was almost complete lack of FRET-positive cells, indicating a reduction in receptor oligomerization. It was concluded that the constitutive activation of the receptor is inhibited by the formation of higher-order complexes, which is prevented by TSH binding, resulting in receptor activation.

WebThyroid Stimulating Hormone (TSH) is produced and released into the bloodstream by the pituitary gland. It stimulates the production of the thyroid hormones, thyroxine (T4) and triiodothyronine (T3), by the thyroid gland by binding to its receptors in the thyroid gland. Thyroxine (T4) and triiodothyronine (T3) are essential for maintaining the ...
