Present Status and Advances in Chimeric Antigen Receptor T Cell Therapy for Glioblastoma

Abstract

Adoptive chimeric antigen receptor (CAR) T cells designed to recognize specific tumor antigens have shown promising results in cancer therapy. While CAR T cell therapy has demonstrated notable clinical effectiveness for hematologic disease, efforts to develop therapies for solid tumors, including glioblastoma (GBM), have been hampered by heterogeneity, an immunosuppressive tumor microenvironment, and difficulty in trafficking. Several specific tumor antigens, such as IL13Rα2, EGFRvIII, and HER2, have been attempted in clinical trials; however, limited efficacy has been observed. In this review, we discuss the current status of CAR T therapy for GBM in clinical trials and highlight the potential target antigens for CAR T cells. Additionally, we summarize the mechanisms used to enhance their efficacy and explore the challenges and future prospects of CAR T cell therapy for GBM.
