Percentages of CD4⁺CD25^highCD127^low/− Tregs among CD4⁺ T cells. Percentages of CD4⁺CD25^highCD127^low/− Tregs among CD4⁺ T cells in the peripheral blood of URSA patients (n = 60) and normal controls (n = 60) are shown. Representative flow cytometry plots for CD4⁺CD25^highCD127^low/− Tregs from (a) a patient with URSA and (b) a normal control subject. c Comparative analysis of the frequencies of CD4⁺CD25^highCD127^low/− Tregs among CD4⁺ T cells in the peripheral blood of URSA patients and normal control subjects (*P < 0.05)
