Figure 1

Comparison of regulatory T cells between G-BM and G-PB. Panel A shows representative plots of CD4⁺CD25^highCD127^-/low regulatory T cells as well as CD69 and CD62L expression on CD4⁺CD25^highCD127^-/low regulatory T cells. Panels B and D show the flow cytometry data for the expression of CD4⁺CD25^highCD62L⁺ regulatory T cells as well as CD4⁺CD25⁻CD69⁺ regulatory T cells in G-BM and G-PB gated on CD4⁺ T cells. Panels C and E show a comparison of the percentage (%CD4⁺ T cells) and the absolute numbers (cells/μl) of the three types of regulatory T cells mentioned above as well as CD4⁺CD25^highCD127^-/lowCD62L⁺ in G-BM and G-PB gated on CD4⁺ T cells (n = 20). *P < 0.05 by Wilcoxon signed-rank test (median with interquartile range).
