Abstract
To assess the potency of regulatory T (Treg) cells induced against an irrelevant Ag, mice were orally vaccinated with Salmonella expressing Escherichia coli colonization factor antigen I fimbriae. Isolated CD25⁺ and CD25⁻CD4⁺ T cells were adoptively transferred to naive mice, and Treg cells effectively protected against experimental autoimmune encephalomyelitis (EAE), unlike Treg cells from Salmonella vector-immunized mice. This protection was abrogated upon in vivo neutralization of TGF-β, resulting in elevated IL-17 and loss of IL-4 and IL-10 production. Thus, Treg cells induced to irrelevant Ags offer a novel approach to treat autoimmune diseases independent of auto-Ag.Entities:
