CD4 and neoplasm: The cell types with anti-tumor effects showed a higher degree of infiltration in the low-risk group (e.g., CD8 T cells, activated memory CD4 T cells, follicular helper T cells, activated B cells and natural killer T cells), while primitive or resting immune cell types (e.g., native CD4 T cells, resting memory CD4 T cells and M0 macrophages) were dominant in the high-risk group (Figure 7E; Supplementary Figure S5C).
