The Roche TSH/thyrotropin receptor antibody (TRAb) assay is a competitive assay using electrochemiluminescence detection. Patient specimen is treated with a reagent buffer consisting of a pre-formed immunocomplex of solubilized porcine thyrotropin (TSH) receptor and biotinylated anti-porcine TSH receptor mouse monoclonal antibody.

The TSH receptor is found mainly on thyroid follicular cells. 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).

There are 3 types of antibodies that bind TSHR, or thyroid receptor antibodies ( TRAb): thyroid-stimulating antibodies (TSAb); TSH-stimulation blocking The thyrotropin receptor (or TSH receptor) is a receptor (and associated protein) that responds to thyroid-stimulating hormone (also known as "thyrotropin") and 1 Apr 1998 The lipolytic effect of hTSH was completely blocked by inhibitory TSH receptor ( TSHR) antibodies.

The thyroid-stimulating hormone receptor (TSHR) is a member of the glycoprotein hormone receptors, a sub-group of class A G-protein-coupled receptors (GPCRs). TSHR and its endogenous ligand thyrotropin (TSH) are of essential importance for growth and function of the thyroid gland and proper function of the TSH/TSHR system is pivotal for production and release of thyroid hormones.

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. 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 ).

Tyreoideastimulerande hormon, TSH, även tyreotropin, sköldkörtelstimulerande hormon, är ett peptidhormon som bildas i hypofysen, vars funktion är att informera sköldkörteln att bilda och frisätta tyreoideahormoner, samt att öka transporten av jod. The thyrotropin receptor (or TSH receptor) is a gene (and associated protein) which responds to thyroid-stimulating hormone (also known as "thyrotropin", and stimulates the production of thyroxine (T4) and triiodothyronine (T3). 1992-05-01 · The extracellular and intracellular domains of the human thyrotropin receptor were expressed in Escherichia coli and the proteins were used to produce monoclonal anti-receptor antibodies. Immunoblot studies and immunoaffinity purification showed that the receptor is composed of two subunits linked by disulfide bridges and probably derived by proteolytic cleavage of a single 90-kDa precursor. 2005-03-29 · Receptor for the thyroid-stimulating hormone (TSH) or thyrotropin (PubMed:11847099, PubMed:12045258).
