CD4 and neoplasm: Results showed a significant connection between MT1X expression and tumor-infiltrating lymphocytes (TILs) (Figure 6B), including central memory CD8 T cells (Tcm-CD8) (ρ = 0.274, P<0.001), central memory CD4 T cells (Tcm-CD4) (ρ = 0.331, P<0.001), γΔ T cells (Tgd) (ρ = 0.292, P<0.001), and macrophages (ρ = 0.284, P<0.001).
