Bar Plot from Scientific Research

Proportions of CD8 + T cells and HPV16-specific (tetramer + ) CD8 + T cells in tumors from different groups were analyzed by flow cytometry 4 weeks after tumor inoculation (mEry, n = 4; alphaPD-1, n = 3; MHC-I-E6, n = 4; MHC-I-E6-mEry, n = 4; MHC-I-E6-mEry plus alphaPD-1, n = 5). Data are presented as means +/- SEM. Significance was determined by two-way ANOVA with Dunnett’s multiple-comparison test ( b ) or one-way ANOVA with Dunnett’s multiple-comparison test ( c , d , g ) or unpaired t -test ( f ). The significance levels are indicated as follows: ns, not significant; * P < 0.05; ** P < 0.01; *** P < 0.001; **** P < 0.0001.
