In some cases it's because of a mutated TSH receptor that inappropriately keeps these follicular cells active.

有时这是因为TSH受体基因突变，不适当地让滤泡细胞保持活跃状态。

These Auto antibodies include thyroid stimulating immunoglobulins which bind to the TSH receptor on the follicular cells and imitate TSH.

这些自身抗体包括甲状腺刺激性免疫球蛋白，它会与滤泡细胞上的TSH受体结合并模仿TSH。
