Figure 1.
Evaluation of TSHR antibodies in GO mouse model. Total TSHR antibodies and stimulating activity of antibodies was measured in sera of individual male or female mice immunized either with ß-Gal (males n = 8, females n = 16) or hTSHR A-subunit plasmid (males n = 14; females n = 14). (A) Total TSHR antibodies (TRAbs) were measured by TSH binding inhibitory immunoglobulin activity to the human TSHR given as % inhibition of TSH. (B) Stimulating activity of antibodies (TSAbs) was evaluated by bioassay using CHO cells stably expressing the mouse TSHR. Stimulating activity is given in cAMP (pmol/ml). Statistical significance is indicated ****p ≤ 0.0001, ***p ≤ 0.001, **p ≤ 0.01, ns not significant.
