Thymic Origin of Intestinal αß T Cells Revealed by Fate Mapping of RORγt + Cells

Eberl, Gérard, Littman, Dan R.·2004·Science

Abstract

Intestinal intraepithelial T lymphocytes (IELs) are likely to play a key role in host mucosal immunity and, unlike other T cells, have been proposed to differentiate from local precursors rather than from thymocytes. We show here that IELs expressingthe αβ T cell receptor are derived from precursors that express RORγt, an orphan nuclear hormone receptor detected only in immature CD4 + CD8 + thymocytes, fetal lymphoid tissue–inducer (LTi) cells, and LTi-like cells in cryptopatches within the adult intestinal lamina propria. Using cell fate mapping, we found that all intestinal αβ T cells are progeny of CD4 + CD8 + thymocytes, indicatingthat the adult intestine is not a significant site for αβ T cell development. Our results suggest that intestinal RORγt + cells are local organizers of mucosal lymphoid tissue.

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.
