Assays for thyrotropin-receptor binding and thyroid-stimulating antibodies in sera from patients with Graves' disease.
We compared the activities of thyroid-stimulating antibodies (TSAb) measured in cultures of human thyrocytes and the values for thyrotropin-receptor antibodies (TRAb) as measured with a commercial kit based on use of radiolabeled receptors. Sera were obtained from patients with Graves' disease before, during, and after therapy with carbimazole (1-methyl-2-thio-3-carbethoxyimidazole). We found a...
متن کاملThe measurement technologies of thyrotropin receptor antibodies from the past to the present
Thyroid Stimulating Hormone Receptor (TSH-R) autoantibodies are the main cause of Graveschr('39') disease and its external thyroid manifestations such as ophtalmopathy and dermatopathy. These antibodies are functionally different and are commonly called TSH receptor antibodies (TRAbs). In fact, TRAbs are a set of autoantibodies including TSHR-stimulating antibodies (TSAbs), TSHR- blocking antib...
متن کاملMonoclonal Antibodies to the Thyrotropin Receptor
The thyrotropin receptor (TSHR) is a seven transmembrane G-protein linked glycoprotein expressed on the thyroid cell surface and which, under the regulation of TSH, controls the production and secretion of thyroid hormone from the thyroid gland. This membrane protein is also a major target antigen in the autoimmune thyroid diseases. In Graves' disease, autoantibodies to the TSHR (TSHR-Abs) stim...
متن کاملGraves' Disease Mechanisms: The Role of Stimulating, Blocking, and Cleavage Region TSH Receptor Antibodies.
The immunologic processes involved in Graves' disease (GD) have one unique characteristic--the autoantibodies to the TSH receptor (TSHR)--which have both linear and conformational epitopes. Three types of TSHR antibodies (stimulating, blocking, and cleavage) with different functional capabilities have been described in GD patients, which induce different signaling effects varying from thyroid c...
متن کاملMonoclonal pathogenic antibodies to the thyroid-stimulating hormone receptor in Graves' disease with potent thyroid-stimulating activity but differential blocking activity activate multiple signaling pathways.
The thyroid target Ag for disease-inducing autoantibodies in Graves' disease is the receptor for thyroid-stimulating hormone (TSH), but little is known about the molecular basis of this pathogenic Ab response. We describe the characteristics of two high- affinity mAbs developed from an experimental murine model of hyperthyroid Graves' disease that exhibit potent thyroid-stimulating activity. Na...
