Figure 2. CD70 is preferentially expressed on memory CD4⁺ and CD8⁺ T cells. Expression of CD70 on each subset (T_N, T_CM, T_EM, and T_EMRA) of CD4⁺ and CD8⁺ T cells. Representative flow data (A, C) and box plots (B, D) of the percentage of CD70 expression on each subset of CD4⁺ (A–B) and CD8⁺ (C–D) T cells from five different age groups (n = 34-56 in each group). Data are shown as the median ± 95% confidence interval (CI). The p-values were obtained by Kruskal-Wallis test followed by Dunn’s multiple comparisons test. *p < 0.05, **p < 0.01, ***p < 0.001.
