The novel Graves disease (GD) model was established in BALB/c mice with recombinant adenovirus expressing the full-length human TSHR (Ad-TSHR289) by three times immunizations for nearly three months. Reducing the frequency of immunizations may shorten the modeling time to improve the efficiency of the study. In this study, female BALB/c mice were immunized one time with an adenovirus expressing the autoantigen thyroid-stimulating hormone receptor (Ad-TSHR289). At the 3, 6, 12, 17 weeks after the immunization, mice were sacrificed. The blood was collected and thyroids were removed. T3, T4, TRAB and thyroid weight/body weight (TW/BW) were tested. Compared with the Normal control (NC) group, the incidence of hyperthyroidism at 3, 6, 12 and 17 weeks after immunization were about 66.67%, 100%, 100%, and 100%. Meanwhile, the incidences of goiter were nearly 50%, 83.33%, 100% and 100% at the same stages. Therefore, modeling rates of GD were about 50%, 83.33%, 100%, 100% at 3, 6, 12 and 17 weeks after immunization. T3 in serum continues to increase from 3 weeks to 17 weeks after immunization. Serum TRAb reached to peak at 6 weeks and remained from 12 weeks after immunization, while T4 and TW/BW had kept steady from 6 weeks. There are positive correlations between T3, T4 and TRAb, TRAb and TW/BW, as well as 13, 14 and TW/BW. GD model can be constructed by primary immunization with Ad-TSHR289, which could be detected at 3 weeks and at least until the 17 weeks after primary immunization. It would improve the efficiency of GD research.
