The composition and correlation of tumor-infiltrating immune cells showed that the risk signature was positively correlated with T cells regulatory (Tregs) and Macrophages M0, and negatively correlated with T cells CD4 memory resting, natural killer (NK) cells activated, Monocytes, Mast cells activated (Fig. 6B and C) and Macrophages M2 (Fig. S5B and C). The gene discussed is CD4; the disease is neoplasm.
