Increased expression of FOXP3 and NFAT1 in rATG-treated CD4⁺ or CD4⁺CD25⁺ T cells. (A) Western blot analysis. rATG increased expression of FOXP3 and NFAT1 in CD4⁺ or CD4⁺CD25⁺ T cells; results are representative of 3 independent experiments. (B) Comparison of rATG and hATG in dose-response of FOXP3 and NFAT1 expression; results are representative of 3 independent experiments.
