Figure 5. Immune cell infiltration and expressions of antigen presenting genes, immune cytolysis genes and immunomodulator genes in tumor tissues by P1/P2 subgroups. (A) Comparisons of cell composition fraction of CD8+ T cells, CD4+ T cells, helper T cells, regulatory T cells, activated natural killer (NK) cells, monocytes, M1 macrophages, M2 macrophages, activated dendritic cells (activated DCs) and neutrophils between P1 and P2 subgroups. (B) Expressions of HLA-A, HLA-B, HLA-C, TAP1 and B2M between P1 and P2 subgroups. (C) Expressions of GZMA and PRF1 between P1 and P2 subgroups. (D) Expressions of PD-1, PD-L1, PD-L2, LAG3, TIM3, CTLA-4, CCR4, TIGIT, CD27 and ICOS between P1 and P2 subgroups.
