Abstract

How commensal microbiota contributes to immune cell homeostasis at barrier surfaces is poorly understood. Lamina propria (LP) T helper 17 (Th17) cells participate in mucosal protection and are induced by commensal segmented filamentous bacteria (SFB). Here we show that MHCII-dependent antigen presentation of SFB antigens by intestinal dendritic cells (DCs) is crucial for Th17 cell induction. Expression of MHCII on CD11c(+) cells was necessary and sufficient for SFB-induced Th17 cell differentiation. Most SFB-induced Th17 cells recognized SFB in an MHCII-dependent manner. SFB primed and induced Th17 cells locally in the LP and Th17 cell induction occurred normally in mice lacking secondary lymphoid organs. The importance of other innate cells was unveiled by the finding that MHCII deficiency in group 3 innate lymphoid cells (ILCs) resulted in an increase in SFB-independent Th17 cell differentiation. Our results outline the complex role of DCs and ILCs in the regulation of intestinal Th17 cell homeostasis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
