WISP1 expression was significantly correlated with infiltrating levels of B cells in 7 types of cancer, CD8+ T cells in 8 types of cancer, CD4+ T cells in 9 types of cancer, macrophages in 17 types of cancer, neutrophils in 15 types of cancer, and dendritic cells in 16 types of cancer (Figure 2A). This evidence concerns the gene CD4 and cancer.
