title: Extrathyroidal synthesis and biologic action of thyroid receptor antibody (TRAb) in Graves' disease.
abstract: In a patient with Graves' disease who underwent thyroidectomy with subsequent radioiodine therapy thyroid receptor antibody could be detected by radioligand assay. No thyroid tissue could be detected by 131I-scintiscanning. Thyroglobulin was repeatedly negative. Biologic activity of this patients serum could be demonstrated in the nude mice bio assay. 131I-incorporation and secretion of human thyroglobulin could be stimulated by injecting thymusdysplastic nude mice with transplants of thyroid tissue from a patient with Graves' disease with the athyroid patients serum. These results demonstrate evidence for extrathyroidal production and biological activity of TRAb in vivo.
