EGFR was highly expressed in aTregs. The expression level of EGFR in three functional subsets of Tregs was detected by using the flow cytometry analysis. (A-D) Gating Strategy was shown. (E) The proportion of three functional subsets of Tregs in EGFR+CD4+T cells. (F-H) The expression level of EGFR was detected on rTregs (I Tregs), aTregs (II Tregs) an nTregs (III Tregs) respectively. All experiments were repeated three times
