摘要
CD8^+T淋巴细胞的亚群不仅具有细胞毒性作用,还能调节机体的免疫反应。具有免疫抑制作用的CD8^+调节性T细胞(Tr)能有效阻断过强的免疫应答,维持机体的免疫稳态。随着医学科学的不断发展,近年来对CD8^+Tr的分型、作用机制及其参与调节自体免疫、器官移植耐受、肿瘤免疫和感染免疫应答等方面的研究取得了巨大进展。
CD8 ^+ regulatory T lymphocyte (CD8^+Tr) is a specific T subset with cytotoxic activity, which could actively regulate immune responses. CD8^+ Tr could suppress unsuitable immune responses and keep the immunological balance of the host. In recent years, a great progress has been made in the study on CD8^+ Tr including their subgroup, functional mechanism, and the immunoregulatory role in autoimmunity, organ transplantation, tumor, infection immunity.
