Although CD8+ T cell infiltration across all cancer groups was minimal (Figure 5C), we observed a signal in specific cancer molecular subtypes (group 3 and 4 MBs) as well as outlier tumors (BRAF-driven LGG, BRAF-driven and WT GNG, and CNS embryonal tumors, not otherwise specified (NOS); Figure S6E). Here, BRAF is linked to cancer.
