Disease-specific markers that are readily measurable and clinically useful are rare. It is surprising, therefore, that it has taken 30 years for the measurement of thyroid-stimulating hormone (TSH or thyrotropin) receptor antibodies (TRAb) in autoimmune thyroid disease to become acceptable to the clinician and available in most respectable clinical laboratories.

Thyroid Stimulating Hormone or TSH or Thyrotropin is a hormone produced by the pituitary gland, a small organ located below the brain and behind the sinus cavities. It …

Stimulation of the receptor increases T 3 and T 4 production and secretion. This occurs through stimulation of six steps in thyroid hormone synthesis: (1) Up-regulating the activity of the sodium-iodide symporter (NIS) on the basolateral membrane of thyroid follicular cells , thereby increasing intracellular concentrations of iodine (iodine trapping). The TSH receptor (TSHR) together with the homologous lutropin/choriogonadotropin receptor and the follitropin receptor are glycoprotein hormone receptors (GPHRs). They constitute a subfamily of the rhodopsin-like G protein-coupled receptors with seven transmembrane helices. Thyroid Stimulating Hormone or TSH or Thyrotropin is a hormone produced by the pituitary gland, a small organ located below the brain and behind the sinus cavities. It is responsible for stimulating the thyroid gland.

From: Clinical Management of Thyroid Disease, 2009. Download as PDF. Thyroid stimulating hormone receptor (TSHR) autoantibodies (TRAb) play a central role in the evaluation of Graves disease (GD), Graves ophthalmopathy (GO) and pretibial myxedema (PTM).

Thyrogen is an exogenous source of human TSH that offers an additional diagnostic tool in the follow-up of patients with a history of well-differentiated thyroid cancer.

Thyrotropin-receptor antibody is an autoantibody to the thyroid cell receptor for thyroid-stimulating hormone. It can be demonstrated in 90% of patients with Graves'

TRAbs are grouped depending on their effects on receptor signalling; activating antibodies (associated with hyperthyroidism), blocking antibodies thyrotropin: [ thi´ro-tro″pin, thi-rot´rah-pin ] a hormone secreted by the anterior lobe of the pituitary gland that has an affinity for and specifically stimulates the thyroid gland . Called also thyroid-stimulating hormone . thyrotropin alfa a recombinant form of human thyrotropin; it binds to thyrotropin receptors and stimulates the steps TRAb (TSH Receptor Binding Antibody) - Measurement of TRAb is used to diagnose and manage Graves' disease, neonatal hypothyroidism, and postpartum thyroid dysfunction. The molecular basis of this disorder resides in the dominant inhibition of endogenous TRs by a mutant receptor, which results in elevation of both serum TSH and TH levels. To confirm that the pituitary was an important locus of negative feedback by TH, a transgenic mouse expressing a pituitary-specific mutant TR (Δ337T) was generated ( 13 ). Thyroid Stimulating Hormone (TSH) Receptor (TSHR-Ab) Antibodies .

Der Thyreotropin-Rezeptor, auch TSH-Rezeptor genannt, ist ein G-Protein-gekoppelter Rezeptor für Thyreotropin auf den Thyreozyten, deren Aktivität er stimuliert.. Es existieren zwei Signalwege: 1) Über das G s-Protein und den cAMP-Signalweg wird die Schilddrüsenhormonfreisetzung und das Wachstum der Schilddrüse angeregt.

Stimulation of the receptor increases T 3 and T 4 production and secretion. This occurs through stimulation of six steps in thyroid hormone synthesis: (1) Up-regulating the activity of the sodium-iodide symporter (NIS) on the basolateral membrane of thyroid follicular cells, thereby increasing intracellular concentrations of iodine Purpose: Thyroid autoimmunity affects approximately 5% of the population, and its investigation relies heavily on the use of autoantibodies. Thyroid stimulating hormone receptor (TSHR) autoantibodies (TRAb) play a central role in the evaluation of Graves disease (GD), Graves ophthalmopathy (GO) and pretibial myxedema (PTM).

This results from the current unsettled state of receptor purification and characterization; hence, the present summary can only be viewed as a state of the art and procedures as they currently exist.
