Thyrotropin Receptors and Gangliosides

1980
Recent studies (1, 2, 28–30, 33–35) have implicated ganglio-sides in the receptor recognition process for thyrotropin (TSH) and have led to the hypothesis (15–17, 19) that the TSH receptor is structurally and functionally related to receptors for other ligands which interact with gangliosides in vitro, i.e., cholera toxin, tetanus toxin, and interferon.

The Influence of Propranolol on the Thyrotropin Receptor

Endocrinology, 1977
Propranolol, a beta adrenergic blocking drug, is known to inhibit the thyrotropin (TSH) stimulation of adenosine-3',5'-monophosphate (cyclic AMP production in thyroid membranes but the mechansim of this inhibitory action is known. We have therefore investigated the influence of propranolol on the binding of 125I-labelled TSH to human thyroid membranes.

Thyrotropin Receptor Antibodies in Early Pregnancy

The Journal of Clinical Endocrinology & Metabolism, 2022
Abstract Context Thyrotropin (TSH) receptor antibodies (TRAb) are important when distinguishing between Graves’ and gestational hyperthyroidism, but sparse evidence exists on the recommended cutoff during pregnancy.

Analysis of the Thyrotropin Receptor-Thyrotropin Interaction by Comparative Modeling

Thyroid, 2004
We have used the most advanced programs currently available to construct the first three-domain structure of the human thyrotropin receptor (TSHR) using comparative modeling. The model consists of a leucine-rich domain (LRD; amino acids 36-281; porcine ribonuclease inhibitor used as a template for modeling), a cleavage domain (CD; amino acids 282-409 ...

The Thyrotropin Receptor in Thyroid Diseases

New England Journal of Medicine, 1997
The growth and function of the thyroid are controlled by thyrotropin1 through the activation of its receptor, which belongs to the large family of G protein–coupled receptors.

Molecular Genetics of the Thyrotropin Receptor

Experimental and Clinical Endocrinology & Diabetes, 2009
Thyroid-stimulating hormone (TSH) receptor has been cloned by a strategy exploiting its belonging to the superfamily of G-protein-coupled receptors. Comparison with the luteinizing hormone and follicle-stimulating hormone receptors shows that the glycoprotein hormone receptors constitute a subfamily of G-protein-coupled receptors with a large ...

Bioassays for thyrotropin receptor autoantibodies

Best Practice & Research Clinical Endocrinology & Metabolism, 2023
Bioassays using animal models were essential tools in the discovery of thyrotropin and in enhancing our understanding of the physiology of the pituitary-thyroid axis. These same bioassays were also instrumental in the discovery of autoantibodies to the thyrotropin receptor (TSH-R-Ab) and in identifying their role in the pathophysiology of Graves ...

Immunological of the Thyrotropin Receptor

Immunological Communications, 1976
Antibodies to the thyrotropin receptor appear to be responsible for hyperthyroidism in Graves' disease. The antibodies, described as thyroid-stimulating antibodies (TSAb) mimic the effects of thyrotropin (TSH) by binding to the TSH receptor and activating adenylate cyclase.

Molecular Cloning of the Thyrotropin Receptor

Science, 1989
The pituitary hormone thyrotropin, or thyroid-stimulating hormone (TSH), is the main physiological agent that regulates the thyroid gland. The thyrotropin receptor (TSHR) was cloned by selective amplification with the polymerase chain reaction of DNA segments presenting sequence similarity with genes for G protein-coupled receptors.
