Additionally, we found positive correlations between HK2 expression and the infiltration score, macrophage, monocyte, natural killer T cells (NKT), T-helper 17 (Th17) cells, and B cells and negative correlations between the nTreg, CD4_naïve, CD8_naïve, and CD8_T groups in GBM patients (Fig. 5B-C). Here, CD8A is linked to glioblastoma.
