摘要
CD4^＋CD25^＋调节性T细胞（Treg）在自身免疫耐受、免疫自稳、肿瘤免疫中发挥着重要作用,它可以抑制自身抗原或者非自身抗原如肿瘤抗原引起的免疫反应.人们对Treg细胞的免疫抑制作用已进行了相关的研究和临床应用,最新研究表明其能够诱导肿瘤特异性抗原和局部的免疫反应.此综述将讨论Treg细胞的相关表面分子及其在肿瘤免疫逃逸机制、肿瘤免疫治疗中的研究进展.
CD4^＋CD25^＋ regulatory T- cell （Treg） play essential roles in maintaining self- tolerance, immune homeostasis and cancer immune system. Treg can suppress immune responses against self antigens or non-selfantigens such as tumor antigens. The immunosuppressive functions of Treg are widely acknowledged and have been extensively studied. Recent studies demonstrate the existence of Treg at tumor sites, implying that these Treg may induce antigen-specific and local immune tolerance. This review will discuss the ligands, mechanisms of immune suppression of Treg and its potential roles in cancer therapy.
