Thyrotrophin-binding inhibiting immunoglobulins (TBII) in subacute thyroiditis. 1983

G Wägar, and T Mäkinen

The occurrence of thyrotrophin-binding inhibiting immunoglobulins (TBII) was determined by the radioligand receptor method in 8 patients with subacute thyroiditis (ST). In the acute phase 2 out of the 6 cases investigated at this stage were TBII positive and one had a borderline TBII value. All three cases were TBII negative when re-investigated more than 3 months later. In the acute phase the serum thyroglobulin (TG) level was 63.8 +/- 61.9 micrograms/l (mean +/- SD, ref. limit less than 26 micrograms/l) and in the later phase 18.2 +/- 9.3 micrograms/l, the TG level being somewhat higher in the TBII positive cases than in the TBII negative cases. Addition of TG to the TBII assay did not affect the displacement of the labelled TSH from the receptor membranes. The occurrence of TBII may be a secondary phenomenon to the follicular destruction seen in the acute phase of ST and indicated by a rise of serum TG. Nevertheless, TBII in ST has the characteristics of a TSH-receptor antibody and it may interfere with the TSH receptor.

D011956	Receptors, Cell Surface	Cell surface proteins that bind signalling molecules external to the cell with high affinity and convert this extracellular event into one or more intracellular signals that alter the behavior of the target cell (From Alberts, Molecular Biology of the Cell, 2nd ed, pp693-5). Cell surface receptors, unlike enzymes, do not chemically alter their ligands.

D011989	Receptors, Thyrotropin	Cell surface proteins that bind pituitary THYROTROPIN (also named thyroid stimulating hormone or TSH) and trigger intracellular changes of the target cells. TSH receptors are present in the nervous system and on target cells in the thyroid gland. Autoantibodies to TSH receptors are implicated in thyroid diseases such as GRAVES DISEASE and Hashimoto disease (THYROIDITIS, AUTOIMMUNE).
