Human peripheral blood lymphocytes were studied with the use of fluorescinated human thyroglobulin (FITC-Tg) for the presence of cells which bind human FITC-Tg (Tg-BL) and which secrete a thyroglobulin antibody (Tg-SL) by culturing them for 5 days with pokeweed mitogen. In seven out of fifteen (47%) patients with Hashimoto's thyroiditis, an average of 0.18% of lymphocytes were able to bind FITC-Tg, while only one out of six (17%) patients with Graves' disease was able to bind them. No Tg-BLs were detected in five patients with miscellaneous autoimmune diseases and five normal subjects. Tg-BLs were identified as B lymphocytes by their inability to make rosettes with sheep red blood cells. Tg-SLs were detected in six out of eight (75%) patients with Hashimoto's thyroiditis and two out of five (40%) patients with Graves' disease. The positive rates of Tg-BL and Tg-SL were fairly well correlated with the thyroglobulin antibody titers.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.

Autoimmune Thyroiditis

Autoimmune thyroiditis is an inflammatory disease of thyroid gland due to autoimmune responses leading to lymphocytic infiltration of the gland. It is characterized by the presence of circulating thyroid antigen-specific T-cells and thyroid autoantibodies. Discover the latest research on autoimmune thyroiditis here.
