CD8A and glioma: T cell compartment and its regulation were the most significant conceptual alteration in anti‐cancer immune response.[6] We analyzed differences in the levels of CD4+ and CD8+ T‐cell infiltration of each subset between the high‐IGLoS and low‐IGLoS groups of patients with glioma and found that patients in the high‐IGLoS group had less CD4+ T cells (Figure S5B, Supporting Information) and more CD8+ T cells (Figure S5C, Supporting Information).
