Abstract

Introduction

Macrophages are essential in maintaining homeostasis, combating infections, and influencing the process of various diseases, including cancer. Macrophages originate from diverse lineages: Notably, tissue-resident macrophages (TRMs) differ from hematopoietic stem cells and circulating monocyte-derived macrophages based on genetics, development, and function. Therefore, understanding the recruited and TRM populations is crucial for investigating disease processes.

Methods

By searching literature databses, we summarized recent relevant studies. Research has shown that tumor-associated macrophages (TAMs) of distinct origins accumulate in tumor microenvironment (TME), with TRM-derived TAMs closely resembling gene signatures of normal TRMs.

Results

Recent studies have revealed that TRMs play a crucial role in cancer progression. However, organ-specific effects complicate TRM investigations. Nonetheless, the precise involvement of TRMs in tumors is unclear. This review explores the multifaceted roles of TRMs in cancer, presenting insights into their origins, proliferation, the latest research methodologies, their impact across various tumor sites, their potential and strategies as therapeutic targets, interactions with other cells within the TME, and the internal heterogeneity of TRMs.

Conclusions

We believe that a comprehensive understanding of the multifaceted roles of TRMs will pave the way for targeted TRM therapies in the treatment of cancer.

癌症中的组织常驻巨噬细胞：是敌是友？

引言巨噬细胞在维持体内平衡、抗感染和影响包括癌症在内的各种疾病的发生过程中起着至关重要的作用。巨噬细胞起源于不同的血系：值得注意的是，组织驻留巨噬细胞（TRMs）与造血干细胞和循环单核细胞衍生巨噬细胞在遗传、发育和功能上有所不同。因此，了解招募的巨噬细胞和TRM群体对研究疾病过程至关重要：通过检索文献数据库，我们总结了近期的相关研究。研究表明，不同来源的肿瘤相关巨噬细胞（TAMs）聚集在肿瘤微环境（TME）中，TRM来源的TAMs与正常TRMs的基因特征非常相似：最近的研究表明，TRMs 在癌症进展中发挥着关键作用。然而，器官特异性效应使 TRM 研究变得复杂。然而，TRMs 在肿瘤中的确切参与还不清楚。这篇综述探讨了TRMs在癌症中的多方面作用，介绍了TRMs的起源、增殖、最新研究方法、对不同肿瘤部位的影响、作为治疗靶点的潜力和策略、与TME内其他细胞的相互作用以及TRMs的内部异质性：我们相信，对TRMs多方面作用的全面了解将为治疗癌症的TRM靶向疗法铺平道路。
