Abstract

Unlike the ∼1% of γδ TCR-positive T cells being regularly present in blood and secondary lymphoid organs (peripheral γδ T cells), ∼50–60% of small intestinal intraepithelial lymphocytes (iIELs) in the mouse express the γδ TCR (γδ iIELs). In this study, we investigated the overlap and exchange of γδ iIELs and γδ T cells found in peripheral secondary lymphoid organs. Using two-photon laser-scanning microscopy, we found γδ T cells within peripheral lymph nodes to be highly motile, whereas γδ iIELs were characterized by a locally confined scanning behavior. Our results implied a strict separation of peripheral γδ T cells and γδ iIELs. Nevertheless, γδ iIELs could be efficiently regenerated from bone marrow-derived precursors in irradiated or T cell-deficient adult mice. However, outside the intestinal epithelium, survival of γδ iIELs was very poor. In CCR9-deficient mice, homing of γδ iIELs was impaired, but did not lead to an accumulation of γδ iIEL-like cells in the periphery. Conversely, in situations in which specific γδ iIEL niches were empty, adoptive transfer of isolated γδ iIELs led to a sustained engraftment of transferred γδ iIELs in the intestinal epithelium for at least 100 d. Furthermore, we demonstrated by heterotopic intestinal transplantation experiments that an exchange of γδ iIELs only rarely happens in the steady state of adult mice. We therefore conclude that peripheral versus intestinal intraepithelial γδ T cells are exclusive, nonoverlapping populations that virtually do not exchange with each other.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Acquisition of surface markers during development such as CD103 (αE integrin), α4β7 and CCR9 ensure homing and tissue residency of IELs.

    “Moreover, acquisition of surface markers during development such as CD103 (αE integrin), α4β7 and CCR9 ensure homing and tissue residency of IELs [324] (see Table 15).”

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.
