Expression levels of CD39 and CD73 on CD8+ T cells in healthy donors and HNSCC patients in comparison. The expression levels of CD8+CD39negCD73+ (a) and CD8+CD39+CD73neg (b) in the different groups were plotted in. The trend of CD8+CD39negCD73+ T cells of tumor and healthy blood cells over increasing ages is plotted in (c) (tumor blood: red squares). Representative density plots for CD8+ healthy donors of different ages (d/e) and TIL (f). All data are plotted showing the mean or the linear regression. P < 0.05 (*); p < 0.01 (**); p < 0.001 (***); p < 0.0001(****)
