Correlation analysis of infiltrating ICs and RPM scores suggested that in most of the 12 tested cancers, RPM scores were significantly negatively correlated with the infiltration of T cells (except for resting CD4+ memory T cells and regulatory T cells) and B cells and were positively correlated with dendritic cells, macrophages, mast cells, and monocytes (Figure 7F). Here, CD4 is linked to cancer.
