Forty-five female DDYK mice were divided into three groups and immunized with different preparations of human thyroglobulin (HTg). Group 1 mice were immunized subcutaneously in the back with HTg emulsified with FCA. Group 2 mice were immunized subcutaneously in the back with HTg dissolved in PBS. Group 3 mice were immunized with HTg dissolved in PBS and FCA separately in the right (HTg) and left (FCA) of the back. After the fourth immunization (45 days after the first immunization), antisera as well as thyroid glands were obtained, and titers of anti-HTg, anti-T3, anti-T4 and the presence of lesions of autoimmune thyroiditis were examined. In group 1 mice, titers of anti-HTg and anti-T4 antibodies were significantly higher than those of the other two groups, whereas titers of anti-T3 antibodies were significantly lower than those of the other two groups. In group 1 mice, a significant correlation between titers of anti-T3 and anti-T4 antibodies was observed, whereas in group 2 and group 3 mice, no such correlation was observed. The incidence of lesions of autoimmune thyroiditis was significantly higher in group 2 and group 3 mice than in group 1 mice. Thus emulsification of HTg with FCA had inhibitory effects on the induction of experimental thyroiditis in mice immunized with HTg. These results indicate the possibility that FCA has a modulatory effect both quantitatively and qualitatively on the immune response against HTg in mice.

The effects of the novel immunosuppressant Deoxyspergualin (DSP) on the development of experimental autoimmune thyroiditis (EAT) in CBA mice were studied. For EAT induction, the mice were immunized with 100 micrograms of porcine thyroglobulin (p Tg) emulsified in CFA on day 0 and in IFA, for boosting, on day 14. Twenty-eight days after primary immunization, histological and serological signs of EAT occurred in control mice treated with PBS which showed marked lymphoid infiltration of the thyroid glands along with increased serum titres of anti-pTg antibodies. Development of both these EAT features was significantly suppressed when the mice were treated with 2.5 mg/kg body weight DSP, given daily, five times a week, from day -2 to day +28 after immunization. The effect appeared to be dose-dependent and DSP was ineffective when given under the same experimental conditions at the dose of 0.5 mg/kg body weight. No DSP-toxic effects could be observed during the experiment. These results provide further evidence for the powerful immunosuppressive properties of DSP and suggest that this drug may be used in the treatment of autoimmune thyroid diseases and other T-cell mediated autoimmune disorders in humans.
