| Outline of Final Research Achievements |
Glioblastoma (GBM) is the most lethal malignant brain tumor in adults despite the improvement on outcomes with this combined chemoradiotherapy approach after maximal surgical resection. In recent years, immunotherapy has emerged as a promising strategy for the treatment of GBM, especially CAR T-cell therapy is considered to be the most promising method to cure cancer. Chimeric antigen receptor (CAR)-transduced T cells can recognize pre-defined tumor surface antigens independent of MHC restriction, which is often downregulated in GBM. We constructed several CARs that recognize antigens expressing on the surface of GBM cells. We also developed new combination therapies to overcome cancer immunosuppression and immune evasion. Additional gene therapy or immunomodulatory drug therapy showed marked improvements in the survival time of the mice models of GBM.
