(A) Expression of ectonucleotidases CD39 and CD73 by different subsets of cytotoxic T-lymphocytes. Differences between groups were evaluated by using nonparametric Mann–Whitney U-test. (B) Expression of ectonucleotidases CD39 and CD73 by various T helper cell subsets. Differences between groups were evaluated by using nonparametric Mann–Whitney U-test. (C) Expression of ectonucleotidases CD39 and CD73 by various Treg cell subsets. Differences between groups were evaluated by using nonparametric Mann–Whitney U-test.
