Composition of heterogeneous infiltrating immune cell subpopulations in Group 1 and Group 2. (A) Relative distribution of all analyzed cell phenotypes in NPC sample tissues. (B-D) Relative distribution analysis of different T cell subtypes between two groups, firstly by separating the total cell number into other, CK+ cells or CD3+ T cells (including all T cell subtypes) (B); then focusing on CD3+ T cells and dividing them into CD4+ T (CD3+CD4+), CD8+ (CD3+CD8+) and other (CD3+CD4-CD8-) cells (C); and finally focusing on CD3+CD4+ T cells and dividing them into Foxp3+ and Foxp3- T cells (D). (E-H) Pairwise comparisons of the density of TIL subpopulations between the two groups for TILs (E), CTLs (F), Teffs (G) and Tregs (H). (I-L) Pairwise comparisons of PDL1 positive TIL subpopulations between the two groups. *p < 0.05, **p < 0.01, ns, not significant.
