CD4 and neoplasm: Pearson correlation analysis shows that, the abundance of immune cells with anti-tumor function (such as Activated CD4 T cell, Activated CD8 T cell, Central memory CD4 T cell, Central memory CD8 T cell) and tumor-suppressor immune cells (such as Regulatory T cell, Type2 T helper cell, CD56dim natural cell) was significantly positively correlated in microenvironment classified by risk score (Figure 7E).
