Chimeric antigen receptor-T cells have spearheaded the field of adoptive cell therapy and shown remarkable results in treating hematological neoplasia. Because different biology solid tumors compared to tumors, response rates CAR-T could not be transferred entities yet. CAR engineering has added co-stimulatory domains, transgenic cytokines switch receptors improve performance persistence a hostile tumor microenvironment, but because inherent type limitations cells, including HLA incompatibility, toxicities (cytokine release syndrome, neurotoxicity) high costs due logistically challenging preparation process for autologous use alternative immune is gaining traction. NK γδ T that do need compatibility or macrophages dendritic with additional properties such as phagocytosis presentation are increasingly seen cellular vehicles potential application. As these possess distinct properties, clinicians researchers thorough understanding their peculiarities commonalities. This review will compare types specific modes action upon activation.

Abstract Chimeric antigen receptor macrophage (CAR-MΦ) represents a significant advancement in immunotherapy, especially for treating solid tumors where traditional CAR-T therapies face limitations. CAR-MΦ offers promising approach to target and eradicate tumor cells by utilizing macrophages’ phagocytic antigen-presenting abilities. However, challenges such as the complex microenvironment (TME), variability expression, immune suppression limit their efficacy. This review addresses these issues, exploring mechanisms of action, optimal construct designs, interactions within TME. It also delves into ex vivo manufacturing CAR-MΦ, discussing autologous allogeneic sources importance stringent quality control. The potential synergies integrating with existing cancer like checkpoint inhibitors conventional chemotherapeutics are examined highlight possible enhanced treatment outcomes. Furthermore, regulatory pathways scrutinized alongside established protocols cells, identifying unique considerations essential clinical trials market approval. Proposed safety monitoring frameworks aim manage adverse events, cytokine release syndrome, crucial patient safety. Consolidating current research insights, this seeks refine therapeutic applications, overcome barriers, suggest future directions transition from experimental platforms standard care options.
