| 中文摘要:肿瘤相关免疫抑制性细胞在肿瘤的发生、发展过程中发挥重要的免疫抑制作用,肿瘤的发展和转移常伴有这些细胞的异常聚集。调节性T细胞(regulatory T cells, Treg)和髓系来源的抑制性细胞(myeloid-derived suppressor cells,MDSC)是免疫抑制性细胞网络的主要成分,它们通过直接或间接作用负向调节其他免疫细胞,抑制抗肿瘤的免疫反应。最新研究显示,有些常规化疗药物除可直接杀伤肿瘤细胞外,还可降低Treg和MDSC的数量,抑制其功能,从而增强抗肿瘤免疫功能。因此,将化疗药物作为预处理方案,凭借其免疫调节作用联合后续的过继性细胞免疫治疗可有效增强抗肿瘤免疫应答。化学免疫治疗策略将改变人们对传统化疗抗肿瘤地位的认识,继而更加合理地应用化疗药物。 |

| Abstract:Cancer-induced immunosuppressive cells play an important immunosuppressive role during the tumor development process, and the development and progression of tumors are always accompanied with abnormal accumulation of cancer-induced immunosuppressive cells. Regulatory T lymphocytes (Treg) and myeloid-derived suppressor cells (MDSC) are major components of these inhibitory cellular networks, and they can inhibit antitumor immune response through multiple mechanisms. Recent studies have provided evidence that beyond their direct cytotoxic or cytostatic effects on cancer cells, some conventional chemotherapeutic drugs and agents used in targeted therapies can promote the elimination or inactivation of suppressive Tregs or MDSCs, resulting in enhanced anti-tumor immunity. Hence, chemotherapeutics, used as a preconditioning regimen and combined with subsequent immunotherapy, can promote anti-tumor immune response. Anticancer chemoimmunotherapy strategy will change the recognization of the role for conventional chemotherapy in anticancer treatment, and it will be helpful to optimize the chemotherapy strategies more reasonably. |
