Figure 1. FOXP3 demethylation in isolated CD4CD25− and CD4CD25hi cells.
A/B. CD4CD25− and CD4CD25hi cells were isolated with Dako MoFlow. DNA was extracted and demethylation (%) of FOXP3 was measured with real-time PCR. C. Intracellular FOXP3 protein was measured in CD4CD25hi cells as described in methods. N = 5, mean ± SEM were shown in B, one representative sample for A/C.
