Antibodies interact with the follicular cell, colloid, or thyroglobulin antigens and activate the complement cascade and cell-mediated cytotoxicity. The progressive destruction of follicles and secondary fibrosis eventually leads to a failure of thyroid hormone production. More than 60 or 70% of the thyroid tissue needs to be destroyed before we see changes in laboratory measures of thyroid fun...

B cells are important for the development of most autoimmune diseases. B cell depletion immunotherapy has emerged as an effective treatment for several human autoimmune diseases, although it is unclear whether B cells are necessary for disease induction, autoantibody production, or disease progression. To address the role of B cells in a murine model of spontaneous autoimmune thyroiditis (SAT),...

etiologic factors for recurrent miscarriage (rm) include autoimmune diseases, the most frequently antiphospholipid syndrome and thyroiditis. some women who suffer from rm might also have an altered immune system. we aimed to evaluate possible associations between anti-thyroid and anti-phospholipid antibodies in women with rm. in a retrospective case series 1 on 156 women with rm, major outcome ...

Thyroglobulin (Tg) is a large glycoprotein of mol.wt. 660000 synthesized in the thyroid. It is the vehicle for the unique route of biological synthesis of thyroxine and contains up to six thyroxyl residues in peptide linkage within its peptide chain. Despite the fact that small quantities are present in the human circulation from birth onwards auto-antibodies to thyroglobulin are commonly found...

Destruction-induced thyrotoxicosis includes various painful diseases such as subacute granulomatous thyroiditis, acute exacerbation of chronic thyroiditis and acute suppurative thyroiditis. In contrast, the clinically painless form of destruction-induced thyrotoxicosis is almost exclusively restricted to painless or silent thyroiditis. We report what we believe to be a case of acute exacerbatio...

Differentiated thyroid cancers include papillary and follicular carcinomas, both originating from follicular epithelium. Treatment of choice is usually total or near total thyroidectomy, followed by ablative radioiodine 131I treatment, and by the long-term administration of thyroid hormone. Despite its excellent prognosis, recurrent disease does occur in approximately 20-40% of patients. Guidel...

PURPOSE We investigated the incidence and risk factors of hypothyroidism after thyroid lobectomy, and evaluated the possibility to predict hypothyroidism preoperatively with serologic markers, such as thyrotropin (TSH), thyroglobulin (TG), anti-thyroglobulin (ATA), and anti-microsomal antibody (AMA). METHODS We enrolled 123 consecutive patients who underwent thyroid lobectomy due to benign co...

OBJECTIVE Cytotoxic T lymphocyte antigen-4 (CTLA-4) is one of the basic antigens involved in immune responses regulation associated with autoimmune thyroid diseases. The aim of the study was to evaluate whether the surface expression of CTLA-4(CD152) on T cells is correlated with laboratory autoimmune markers in children with Hashimoto's disease. MATERIAL AND METHODS Blood samples were obtain...
