It is a seven transmembrane G protein-coupled receptor that is involved in thyroid hormone signalling. 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 .

Thyrotropin receptor

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' disease, and is the cause of the hyperthyroidism of that condition. Thyrotropin Receptor Antibody Test. The Thyrotropin Receptor Antibody (TRAb) Test is used to aid in the diagnosis of autoimmune disorders which affect the Thyroid. Thyrotropin Receptor Antibodies are the cause of Hyperthyroidism in people with condition's such as Grave's Disease and will be present in approximately 90% of people with this The thyrotropin receptor (TSH receptor) is the antigen for TSH receptor antibodies (TRAbs). It is a seven transmembrane G protein-coupled receptor that is involved in thyroid hormone signalling.

4135-4138. Forskningsoutput: Tidskriftsbidrag › Artikel i vetenskaplig Tyreotropinfrisättande hormon, TRH (thyrotropin-releasing hormone) eller protirelin (C16 H22 N6 O4) är ett peptidhormon som bildas i hypotalamus för att frisätta hormoner i hypofysen.

Among the autoantibodies found in autoimmune thyroid disease, thyrotropin receptor autoantibodies (TRAb) are most closely associated with disease pathogenesis. All forms of autoimmune thyrotoxicosis (Graves disease; GD, Hashitoxicosis, neonatal thyrotoxicosis) are caused by the production of stimulating TRAb-.

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). However, there is still controversy regarding overall TRAb assay diagnostic accuracy and their prognostic utility.

Thyrotropin receptor, still much to be learned from the patients. Briet C(1), Suteau-Courant V(2), Munier M(3), Rodien P(4).

[1] The thyrotropin receptor (TSHR) is a seven-transmembrane protein that belongs to the family of G-protein-coupled receptors (GPCR). The receptor is located on the surface of thyroid follicular cells, and its activation leads to thyroid hormone production and growth and proliferation of thyrocytes.

Binding of thyrotropin alfa to TSH receptors on thyroid epithelial cells stimulates decreased free tri-iodothyronine, increased blood TSH, hypothyroidism*.

The activity of this receptor is mediated by G proteins which activate adenylate cyclase (By similarity). 1990-12-05 · The thyrotropin (TSH) receptor belongs to a family of guanine nucleotide protein-coupled receptors with seven transmembrane-spanning regions joined regulatory together by extracellular and intracellular loops. The large TSH-bound ectodomain of the thyrotropin receptor (TSHR) activates the transmembrane domain (TMD) indirectly via an internal agonist (IA). The ectodomain/TMD interface consists of a converging helix, a Cys-Cys-bridge–linked IA, and extracellular loops (ECL).
