Throu...

The research examines the immunobiology of glioblastoma (GBM) and explains why standard immunotherapies often fail to treat this aggressive brain tumor. While common animal models show high levels of exhausted T cells , human patients actually possess a different landscape dominated by GZMK⁺ T cells and very low mutation rates. This low tumor mutational burden results in minimal antigen stimulatio...
