Allo-aca alleviates autoimmune thyroiditis caused by high iodine intake. (A) In normal mouse thyroid, the follicles were distributed evenly and there were no infiltrated inflammatory cells. High iodine intake caused autoimmune thyroiditis (EAT) in NOD mice, which was characterized by structural damage to thyroid follicles. Whereas treatment with Allo-aca attenuated the destruction of thyroid follicular cells. (B) Allo-aca significantly reduced the number of lymphocytes in the thyroid gland according to the lymphocyte infiltration score. (C) The body weight of mice was continuously monitored during the experimental period, and there was no statistical difference in body weight among the three groups. n = 4, data are expressed as mean ± standard deviation, **P < 0.01, ***P < 0.001.
