Autoimmune thyroid diseases （AITD） are destructive inflammatory or anti-receptor autoimmune diseases characterized by reactivity to self-thyroid antigens. However, the effects of Se on the cytokines in AITD are still unclear. So we researched the role of Selenium （Se） and Thl/Th2 cytokine productions in the pathogenesis of autoimmune thyroid diseases （AITD）.展开更多
