Abstract:
Objective To explore the role of regulatory T-lymphocytes(Treg) in the immune pathogenesis of suba-cute thyroiditis (SAT). Methods The proportion of Treg in CD4+T cells in peripheral blood of 46 SAT patients and15 controls was detected using flow cytometry. And the concentration of interleukin-10(IL-10), transforming growth factor-beta1(TGF-β1) and prostaglandin E2(PGE2) in serum of 46 SAT patients and 15 controls was measured with ELISA. In addition, the Forkhead box protein 3 (Foxp3) positive cells in thyroid tissue of 29 SAT patients and20 controls was detected by immunohistochemistry. Results The proportion of Treg in peripheral blood of SAT pa-tients was significantly lower than that of controls (P＜0.05). And the concentration of TGF-β1 in serum of SAT patients was apparently higher than that of controls(P＜0.05). Additionally, the positive rate of Foxp3 in thyroid tissue of SAT patients was markedly higher than that of controls(P＜0.05).Conclusions The decrease of Treg may play an important role in the immune pathogenesis of SAT.
