[Progressin Tumor-Associated Macrophages in the Treatment of Pancreatic Cancer].

Pancreatic cancer is one of the digestive system tumors with a high degree of malignancy,and most of the patients are diagnosed in advanced stages.Because of limited available therapies,the mortality of this disease remains high.Tumor-associated macrophages(TAM),the main immune cells in the tumor microenvironment,are involved in the regulation of the occurrence and development of pancreatic cancer.Specifically,TAM are involved in the proliferation,invasion,immune escape,and chemoresistance of pancreatic cancer cells,demonstrating potential in the targeted therapy of pancreatic cancer.In this paper,we summarize the TAM-based therapies including consuming TAM,reprogramming TAM,dynamic imaging of TAM with nanoprobes,and regulating the phagocytic ability of TAM for pancreatic cancer,aiming to provide a theoretical basis for developing new therapies for pancreatic cancer.胰腺癌是恶性程度非常高的消化系统肿瘤之一,诊断时大多为晚期阶段,目前治疗方法较为局限,患者的死亡率也较高。肿瘤相关巨噬细胞(TAM)是肿瘤免疫微环境中主要的免疫细胞,可参与胰腺癌发生发展的调控,包括胰腺癌细胞的增殖、侵袭、免疫逃逸及化疗耐药等,在胰腺癌的靶向治疗中显示出一定的治疗潜力。本文总结了目前基于TAM治疗胰腺癌的策略,包括消耗TAM、重新编程TAM、纳米探针用于TAM的动态成像以及调节TAM的吞噬能力等,以期为胰腺癌临床治疗寻找新的思路提供理论依据。.
