CD4 and glioblastoma: The results show that in GBM, the infiltration of DC and CD4+ T cells were lower with chromosome arm-level gain of TP53I13, while in LGG, infiltration of B cells and DC were higher with chromosome arm-level deletion of TP53I13. Different immunological subgroups’ TP53I13 expression was assessed, as seen in Supplementary Figures 6B, C.
