Intestinal cDC1 drive cross-tolerance to epithelial-derived antigen via induction of FoxP3CD8 T.

Sci Immunol 2021 06;6(60)

Mucosal Immunology Group, Department of Health Technology, Technical University of Denmark, Kemitorvet, Kgs. Lyngby 2800, Denmark, Denmark.

Although CD8 T cell tolerance to tissue-specific antigen (TSA) is essential for host homeostasis, the mechanisms underlying peripheral cross-tolerance and whether they may differ between tissue sites remain to be fully elucidated. Here, we demonstrate that peripheral cross-tolerance to intestinal epithelial cell (IEC)-derived antigen involves the generation and suppressive function of FoxP3CD8 T cells. FoxP3CD8 T generation was dependent on intestinal cDC1, whose absence led to a break of tolerance and epithelial destruction. Read More
