甲状腺相关性眼病(TAO)是一种器官特异性自身免疫性疾病，其引起的一系列症状使患者的健康水平、生活质量明显下降。TAO的发病机制尚未完全阐明，目前缺乏统一、成熟的治疗方案。辅助性T17(Th17)细胞、调节性T(Treg)细胞及其失衡与TAO的免疫学发病机制密切相关。目前认为Th17细胞所分泌的细胞因子可促进TAO的炎症反应和眼眶结缔组织的纤维化，抑制TAO眼眶结缔组织的成脂分化。而Treg细胞对TAO的影响以发挥免疫抑制作用、延缓疾病进展为主。Th17、Treg细胞之间存在动态平衡关系，Th17/Treg细胞的失衡能够推动TAO的发生发展。本文主要阐述Th17、Treg细胞及其平衡对TAO的影响机制，并对不同研究结果间的差异原因进行分析，以期为TAO发病机制的研究及临床对因治疗提供一定参考。

[Abstract]
Thyroid-associated ophthalmopathy(TAO)is an organ-specific autoimmune disease, which will cause a series of symptoms to significantly reduce the health level and life quality of patients. The pathogenesis of TAO has not been fully clarified. At present, there is a lack of unified and mature treatment scheme of it. Indeed, T-helper 17 lymphocyte(Th17)cells, regulatory T(Treg)cells and their imbalance are closely related to the immunological pathogenesis of TAO. It is currently believed that the cytokines secreted by Th17 cells can not only promote the inflammatory response of TAO and the fibrosis of orbital connective tissue, but also inhibit the adipogenic differentiation of TAO orbital connective tissue. In addition, Treg cells mainly exert immunosuppressive effect on TAO and delay the disease progression. At the same time, there is a dynamic balance relationship between Th17 and Treg cells, the imbalance of Th17/Treg cells can trigger the occurrence and development of TAO. This paper mainly expounds the influence mechanism of Th17, Treg cells and their balance on TAO, and analyzes the reasons for the differences between different research results, so as to provide some reference for the study of the pathogenesis and clinical treatment of TAO.
