CD4 and cancer: Among the diverse infiltrates, we found that CBX4 expression was shown to have significant correlations with infiltrating B cells in 33 types (Figure 4A), infiltrating CD4+ T cells in 36 types (Figure 4B), myeloid derived suppressor cells (MDSCs) in 17 types (Figure 4C) and cancer associated fibroblast (CAFs) in 28 types of the 40 cancers (Figure 4D) (p < 0.05).
