Macrophages strongly influence cancer progression through their adaptable phenotypes and responses to mechanical and biochemical cues. Their abundance across tumors and links to poor outcomes drive interest in macrophage-targeted therapies. This review highlights macrophage mechanobiology, key behaviors, and the potential of engineered macrophages, using genetic (CAR) or non-genetic "Trojan horse" and "backpacking" strategies, to deliver therapies and reshape the immunosuppressive tumor microenvironment.
