Additionally, CLU expression exhibited positive correlations with monocytes (r = 0.3, p = 0.00012) and resting memory CD4 T cells (r = 0.26, p = 0.00069), while negative correlations with macrophage M0 (r = −0.17, p = 0.031) and M2 (r = −0.33, p = 1.7 × 10−5) in GBM, which were inconsistent with the findings in LGG, and the detailed comparison of various parameters between LGG and GBM is shown in Table 1 and Table 2. The gene discussed is CD4; the disease is glioblastoma.
