In vivo TGF-β neutralization reduces the expression of Foxp3. At the peak of EAE, FACS analysis for Foxp3 expression on CD4+ T cells was performed on cells obtained from mice adoptively transferred with Salmonella-CFA/I (H696)- or Salmonella vector (H647)-induced CD25+CD4+ and CD25− CD4+ T cells and co-administered IgG1 or anti-TGF-β mAb.
