PG - 52-64 LID - 10.1111/imm.12747 [doi] AB - Dendritic cells (DCs) in mesenteric lymph nodes (MLNs) induce Foxp3(+) regulatory T cells to regulate immune responses to beneficial or non-harmful agents in the intestine, such as commensal bacteria and foods. Several studies in MLN DCs have revealed that the CD103(+) DC subset highly induces regulatory T cells, and another study has reported that MLN DCs from programmed death ligand 1 (PD-L1) -deficient mice could not induce regulatory T cells. Hence, the present study investigated the expression of these molecules on MLN CD11c(+) cells. Four distinct subsets expressing CD103 and/or PD-L1 were identified, namely CD11b(+) CD103(+) PD-L1(High) , CD11b(-) CD103(+) PD-L1(High) , CD11b(-) CD103(+) PD-L1(Low) and CD11b(+) CD103(-) PD-L1(Int) . Among them, the CD11b(-) CD103(+) PD-L1(High) DC subset highly induced Foxp3(+) T cells. This subset expressed Aldh1a2 and Itgb8 genes, which are involved in retinoic acid metabolism and transforming growth factor-beta (TGF-beta) activation, respectively. Exogenous TGF-beta supplementation equalized the level of Foxp3(+) T-cell induction by the four subsets whereas retinoic acid did not, which suggests that high ability to activate TGF-beta is determinant for the high Foxp3(+) T-cell induction by CD11b(-) CD103(+) PD-L1(High) DC subset. Finally, this subset exhibited a migratory DC phenotype and could take up and present orally administered antigens. Collectively, the MLN CD11b(-) CD103(+) PD-L1(High) DC subset probably takes up luminal antigens in the intestine, migrates to MLNs, and highly induces regulatory T cells through TGF-beta activation.
