As expected, in CCL2-high GBM, the immune score and correlation of CD4+ T cells (Fig. 5A-B), macrophages (Fig. 5C-D), neutrophils (Fig. 5E-F), myeloid dendritic cells (Fig. 5G-H), and NK cells (Fig. S6E-F) were all significantly increased compared with CCL2-low GBM. This evidence concerns the gene CD4 and glioblastoma.
