Figure 4. Expression of E2F2 was related to a panel of gene markers of immune cells, including M1 cells (A), M2 cells (B), Th1 cells (C), Th2 cells (D), Treg cells (E) and PD-1/PD-L1 (F). (G) E2F2 CNV affects the infiltrating levels of B cells, CD8+ T cells, CD4+ T cells, macrophages, neutrophils and dendritic cells in GC.
