CAR-T-cell therapy in meningioma: current investigations, advancements and insight into future directions.

Meningiomas, the most common tumors of the central nervous system (CNS), present significant challenges in treatment, particularly for atypical and anaplastic subtypes where standard therapies often fall short of therapeutic expectations. Chimeric antigen receptor (CAR) T-cell therapy, a groundbreaking immunotherapy approach, has demonstrated great success in hematological malignancies but faces obstacles in solid tumors, including CNS tumors like glioblastomas. This article provides a comprehensive review of the efficacy of CAR-T therapy in meningiomas, highlighting the tumor's immunogenic potential and the challenges associated with applying this therapy in clinical practice. Through an extensive literature review, the study explores potential antigens for CAR-T targeting in meningiomas, shedding light on the tumor-immune microenvironment interactions. Challenges such as tumor heterogeneity, blood-brain barrier penetration, off-target effects, and tumor recurrence are discussed, alongside potential strategies to overcome these obstacles. The study also investigates recent advancements in CAR-T therapy, including the identification of novel target antigens and the development of engineering approaches to enhance therapeutic efficacy. Furthermore, the article highlights the importance of ongoing research efforts in exploring the tumor-immune dynamics in meningiomas and underscores the urgent need for clinical trials to validate the safety and efficacy of CAR-T therapy in this context. By addressing these challenges, CAR-T therapy holds the promise of revolutionizing meningioma treatment, offering new hope for patients suffering from this disease.
