CD8A and neoplasm: Such significant negative correlations between the prognostic bacteria and tumor-suppressive TILs were also observed when each genus was examined (Supplementary Fig. 5); CD45 RO+ T cells in Bacteroides (P < 0.001), CD8+ and CD45RO+ T cells in Lactobacillus (P = 0.009, P = 0.007, respectively), and CD4+ and CD8+ cells in Peptoniphilus (P = 0.004, P = 0.017, respectively).
