Abstract
Autoantibodies against thyroid proteins are present in several thyroid diseases. Thyroid-stimulating hormone receptor (TSHR) is a G-protein-coupled receptor (GPCR) that binds to thyroid-stimulating hormone (TSH) and stimulates production of thyroxine (T4) and triiodothyronine (T3). When agonized by anti-TSHR autoantibodies, aberrant production of thyroid hormone can lead to Graves' Disease (GD). In Hashimoto's thyroiditis (HT), anti-TSHR autoantibodies target the thyroid for immune attack. To better understand the role of anti-TSHR antibodies in thyroid disease, we generated a set of rat antimouse (m)TSHR monoclonal antibodies with a range of affinities, blocking of TSH, and agonist activity. These antibodies could be used to investigate the etiology and therapy of thyroid disease in mouse models and as building blocks in protein therapeutics that target the thyroid for treatment in either HT or GD.
