title: Cutting edge: antigen-specific TGF beta-induced regulatory T cells suppress Th17-mediated autoimmune disease.
abstract: CD4(+) T cells from the TCR transgenic TxA23 mouse recognize a peptide from the H/K-ATPase alpha-chain. When TxA23 CD4(+) thymocytes are differentiated into Th1, Th2, and Th17 lines, all three subpopulations induced autoimmune gastritis (AIG) upon transfer into nu/nu recipients. The induction of AIG by naive T cells or by Th1 or Th2 cell lines could be prevented by the cotransfer of polyclonal Foxp3(+) T regulatory cells (nTreg), whereas Th17-induced AIG was resistant to suppression. We compared the capacity of different types of Treg to suppress Th17-mediated AIG. Cotransfer of either nTreg or polyclonal TGFbeta-induced Treg (iTreg) did not prevent AIG, while cotransfer of TGFbeta-induced Ag-specific TxA23 iTreg completely prevented the development of disease. Ag-specific iTreg were able to suppress Th17-mediated disease when injected 6 days after the Th17 effectors. The implications of these results for the use of Treg for the cellular biotherapy of autoimmune disease are discussed.
