Leveraging the Mononuclear Phagocyte System for Advancing Glioma Theranostics: Current Insights and Future Directions

ABSTRACT Gliomas present a significant challenge in oncology due to their often subtle early symptoms and the insidious nature of their growth, which is compounded by the blood–brain barrier. Recent evidence has highlighted the diagnostic and therapeutic potential of monocytes, macrophages, and microglia in the context of glioma. This review focused on emerging evidence and hypotheses concerning the components and interrelationships within the mononuclear phagocyte system (MPS) in the central nervous system and its role in glioma development and invasion. By summarizing the involvement of the MPS in glioma biology, this paper offers a novel perspective for the integration of liquid biopsy and targeted therapies in oncology.
