Figure 5B shows significant correlations between KCTD5 expression and the abundance of infiltrating immune cells: significant correlations with CD8 + T cells were found in 17 types of cancer, with CD4 + T cells in 8 types of cancer, with neutrophils in 20 types of cancer, with DCs in 22 types of cancer, with macrophages in 18 types of cancer, and with B cells in 14 types of cancer. This evidence concerns the gene KCTD5 and cancer.
