摘　　要：髓源性抑制细胞(myeloid-derived suppressor cells,MDSCs)是一组具有强大免疫抑制功能的细胞。近年来,有关其在肿瘤发生和发展过程中的作用备受重视。许多临床研究发现,MDSCs在肿瘤患者的血液和瘤体内大量聚集,其水平的升高与肿瘤的不良预后密切相关,是一种有价值的肿瘤预测标志物;同时,MDSCs的免疫抑制功能亦可降低抗肿瘤的疗效。因此,探究MDSCs在肿瘤微环境中发挥免疫抑制作用的具体机制可为寻找新的免疫治疗方法提供参考。Myeloid-derived suppressor cells(MDSCs) are a group of cells with potent immune suppressive activity which have emerged as an important contributor to tumor progression and genesis. More and more clinical researches have found that accumulation of MDSCs in peripheral blood and tumor tissues could predict dismal outcome for patients with malignancies, which was a potential prognostic tumor marker. In addition, immunosuppression induced by MDSCs could reduce the efficacy of anti-tumor therapies. Therefore, better understanding the mechanism of MDSCs’ immune suppression in tumor microenvironment can provide reference for exploring new immunotherapies.
