A monoclonal thyroid-stimulating antibody.
The thyrotropin receptor, also known as the thyroid-stimulating hormone receptor (TSHR), is the primary antigen of Graves disease. Stimulating TSHR antibodies are the cause of thyroid overstimulation and were originally called long-acting thyroid stimulators due to their prolonged action. Here we report the successful cloning and characterization of a monoclonal antibody (MS-1) with TSHR-stimul...
متن کاملThyroid-stimulating Antibody Activity
To investigate the distribution of thyroid-stimulating antibody (TSAb) activity between IgG subclasses, sera from 11 patients with Graves disease (including the National Institute of Biological Standards and Control (NIBSC) Research Standard, long acting thyroid stimulator-B) were fractionated by chromatography on affinity columns of monoclonal IgG subclass antibodies or protein A to deplete al...
متن کاملConcentration-dependent regulation of thyrotropin receptor function by thyroid-stimulating antibody.
Thyrotropin receptor (TSHR) Ab's of the stimulating variety are the cause of hyperthyroid Graves disease. MS-1 is a hamster mAb with TSHR-stimulating activity. To examine the in vivo biological activity of MS-1, mice were treated with purified MS-1 intraperitoneally and the thyroid response evaluated. MS-1 induced a dose-dependent increase in serum thyroxine (T4), with a maximum effect after 10...
متن کاملUnlike thyrotropin, thyroid-stimulating antibodies do not activate phospholipase C in human thyroid slices.
The effects of thyroid-stimulating antibodies (TSAb) and of thyrotropin (TSH) were compared, on the generation of cyclic AMP and inositol phosphates (InsP), in human thyroid slices incubated in vitro, and on the Rapoport cyclic AMP bioassay. The TSAb positive sera were obtained from 19 patients with Graves' disease. In 14 experiments with the slices system, TSH significantly increased cyclic AM...
