Research Abstract

In this study, we aimed to elucidate the mechanism by which human immunodeficiency virus (HIV)-specific cytotoxic T lymphocytes (CTLs) are induced in the intestine. HIV-1 Gag-expressing Salmonella typhimurium aroA- or aroA-invAmutants, which can or not, respectively, penetrate Peyer's patches, were used as oral antigens into mice. However, Gag-specific CTLs were hardly induced in both the systemic and the gut mucosal compartments. Further study should be needed for better understanding of the role of Peyer's patches in the induction of mucosal CTLs.
