Proportion of naïve CD4+ and Tregs. Proportion of CD4+ T cells and Tregs that are naïve (CD27+CD45RA+ or CD45RA+ for Treg) were examined by age group. In subjects with no surgery, proportion of CD4+ T cells and CD4+ Tregs that are naïve decrease between childhood and adulthood (P = .007, P = .025; Mann-Whitney test). In subjects with low TREC median proportion of naïve cells is reduced compared with no Surgery at each age (*P < .03), but there is no difference between children and adults (P = n.s. for both; Mann-Whitney test).
