CD4+ Lymphoid Tissue-Inducer Cells Promote Innate Immunity in the Gut
Open accessAbstract
SUMMARY Fetal CD4+ lymphoid tissue inducer (LTi) cells play a critical role in the development of lymphoid-tissues. Recent studies identified that LTi cells persist in adults and are related to a heterogeneous population of innate lymphoid cells that have been implicated in inflammatory responses. However, whether LTi cells contribute to protective immunity remains poorly defined. We demonstrate that following infection with Citrobacter rodentium, CD4+ LTi cells were a dominant source of interleukin-22 (IL-22) early during infection. Infection-induced CD4+ LTi cell responses were IL-23-dependent, and ablation of IL-23 impaired innate immunity. Further, depletion of CD4+ LTi cells abrogated infection-induced expression of IL-22 and anti-microbial peptides, resulting in exacerbated host mortality. LTi cells were also found to be essential for host protective immunity in lymphocyte-replete hosts. Collectively these data demonstrate that adult CD4+ LTi cells are a critical source of IL-22 and identify a previously unrecognized function for CD4+ LTi cells in promoting innate immunity in the intestine.

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.
