类风湿关节炎(RA)是一种以对称性多发性关节炎为主要临床表现的全身性、异质性自身免疫性疾病。自身免疫性疾病的基本原因是对自身或无害抗原的耐受性丧失。在人类自身免疫性疾病中,已经证实了关键免疫细胞--调节性T(Treg)细胞的丢失或功能缺陷。类风湿性关节炎的发病机制复杂,Tregs功能障碍是导致自身耐受性下降导致类风湿关节炎进展的机制之一。Treg细胞是外周免疫耐受的重要组成部分,转录因子Foxp3起着重要的免疫抑制作用。类风湿关节炎的临床治疗主要是通过药物来减缓疾病的进展和缓解疾病的活动性,理想的治疗策略应该是在明显的组织损伤之前重新诱导自身耐受。Treg细胞是理想的选择之一。现就RA中Treg细胞的分类、作用机制及特点作一综述,以期为临床RA的治疗提供参考。
Rheumatoid arthritis (RA) is a systemic and heterogeneous autoimmune disease with symmetrical polyarthritis as its critical clinical manifestation. The basic cause of autoimmune diseases is the loss of tolerance to self or harmless antigens. The loss or functional deficiency of key immune cells, regulatory T (Treg) cells, has been confirmed in human autoimmune diseases. The pathogenesis of RA is complex, and the dysfunction of Tregs is one of the proposed mechanisms underlying the breakdown of self-tolerance leading to the progression of RA. Treg cells are a vital component of peripheral immune tolerance, and the transcription factor Foxp3 plays a major immunosuppressive role. Clinical treatment for RA mainly utilizes drugs to alleviate the progression of disease and relieve disease activity, and the ideal treatment strategy should be to re-induce self-tolerance before obvious tissue injury. Treg cells are one of the ideal options. This review will introduce the classification, mechanism of action, and characteristics of Treg cells in RA, which provides insights into clinical RA treatment.
