摘　　要：癌症免疫疗法已成为一种新型癌症治疗方法,而复杂的肿瘤微环境(Tumor microenvironment, TME)极大限制其临床应用。肿瘤微环境的重要组成部分是肿瘤相关巨噬细胞(Tumor-associated Macrophages, TAMs),它们通常与不良预后相关,并已成为增强癌症免疫疗效的有希望的靶标。最近,由于纳米颗粒独特的物理化学特性,将免疫治疗与纳米递送系统联合使用可实现更高的疗效。在这篇综述中,我们主要描述了纳米药物重塑TAMs用于增强癌症免疫治疗的策略,包括抑制TAMs被招募到肿瘤部位、清除TAMs、将M2型TAMs重编程为M1型TAMs、调节TAMs对肿瘤细胞的吞噬能力,还描述了目前工程化巨噬细胞的研究现状。Cancer immunotherapy has become a new type of cancer treatment, and the complex tumor microenvironment (TME) greatly limits its clinical application. Tumor-associated macrophages (TAMs), as an important component of the tumor microenvironment, are usually associated with poor prognosis and have become promising targets for enhancing the immune efficacy of cancer. Recently, due to the unique physical and chemical properties of nanoparticles, the combination of immunotherapy and nano-delivery systems can achieve higher efficacy. In this review, we mainly described the strategies of reshaping TAMs with nano-drugs to enhance cancer immunotherapy, including inhibiting the recruitment of TAMs to tumor sites, clearing TAMs, reprogramming M2-type TAMs into M1-type TAMs, regulating the phagocytic ability of TAMs to tumor cells, and also described the current research status of engineered macrophages.
