BACKGROUND
Cancer immunotherapy has emerged as a groundbreaking approach in cancer treatment, primarily realized through the manipulation of immune cells, notably T cell adoption and immune checkpoint blockade. Nevertheless, the manipulation of T cells encounters formidable hurdles. Macrophages, serving as the pivotal link between innate and adaptive immunity, play crucial roles in phagocytosis, cytokine secretion, and antigen presentation. Consequently, macrophage-targeted therapies have garnered significant attention.
AIM OF REVIEW
We aim to provide the most cutting-edge insights and future perspectives for macrophage-targeted therapies, fostering the development of novel and effective cancer treatments.
KEY SCIENTIFIC CONCEPTS OF REVIEW
To date, the forefront strategies for macrophage targeting encompass: altering their plasticity, harnessing CAR-macrophages, and targeting phagocytosis checkpoints. Macrophages are characterized by their remarkable diversity and plasticity, offering a unique therapeutic target. In this context, we critically analyze the innovative strategies aimed at transforming macrophages from their M2 (tumor-promoting) to M1 (tumor-suppressing) phenotype. Furthermore, we delve into the design principles, developmental progress, and advantages of CAR-macrophages. Additionally, we illuminate the challenges encountered in targeting phagocytosis checkpoints on macrophages and propose potential strategies to overcome these obstacles.
背景
癌症免疫疗法已成为癌症治疗中的一种开创性方法，主要通过对免疫细胞的操控来实现，特别是T细胞改造和免疫检查点阻断。然而，T细胞的操控面临巨大障碍。巨噬细胞作为先天性免疫和适应性免疫之间的关键纽带，在吞噬作用、细胞因子分泌和抗原呈递中发挥着关键作用。因此，针对巨噬细胞的疗法备受关注。
综述目的
我们旨在为针对巨噬细胞的疗法提供最前沿的见解和未来展望，推动新型有效癌症治疗方法的发展。
综述的关键科学概念
迄今为止，针对巨噬细胞的前沿策略包括：改变其可塑性、利用嵌合抗原受体巨噬细胞（CAR-巨噬细胞）以及靶向吞噬检查点。巨噬细胞具有显著的多样性和可塑性，提供了一个独特的治疗靶点。在此背景下，我们批判性地分析了旨在将巨噬细胞从M2（促肿瘤）表型转变为M1（抑肿瘤）表型的创新策略。此外，我们深入探讨了CAR-巨噬细胞的设计原则、发展进展和优势。此外，我们阐明了在靶向巨噬细胞吞噬检查点时遇到的挑战，并提出了克服这些障碍的潜在策略。
