A therapeutic expressing enterotoxigenic colonization aspect antigen I (CFA/I) fimbriae protects against collagen-induced arthritis (CIA) by eliciting two regulatory T cell (Treg) subsets: TGF-β-producing Foxp3?CD39+CD4+ and IL-10-producing Foxp3+CD39+CD4+ T cells. diseases. Subsequent evaluation revealed that a single oral dose of purified soluble CFA/I fimbriae protected against CIA as effectively as leading to a prolonged parasitemia… Continue reading A therapeutic expressing enterotoxigenic colonization aspect antigen I (CFA/I) fimbriae protects
