TGF-β1-DCs can increase the relative numbers of CD4+Foxp3+ Tregs in vivo and in vitro. (a) The relative CD4+Foxp3+Treg numbers from spleens of each group mice. (b) The relative CD4+Foxp3+ Treg numbers from mLNs of each group mice. CD4+ cells were gated and analyzed for Foxp3+ Tregs. (c) TGF-β1-DCs can increase the relative numbers of CD4+Foxp3+ Tregs in vitro. *P < 0.05, **P < 0.01; data are representative of three independent experiments (n = 3). DC, dendritic cell; TGF-β1, transforming growth factor-β1.
