Abstract

In the small intestine, type 2 responses are regulated by a signaling circuit that involves tuft cells and group 2 innate lymphoid cells (ILC2s). Here, we identified the microbial metabolite succinate as an activating ligand for small intestinal (SI) tuft cells. Sequencing analyses of tuft cells isolated from the small intestine, gall bladder, colon, thymus, and trachea revealed that expression of tuft cell chemosensory receptors is tissue specific. SI tuft cells expressed the succinate receptor (SUCNR1), and providing succinate in drinking water was sufficient to induce a multifaceted type 2 immune response via the tuft-ILC2 circuit. The helminth Nippostrongylus brasiliensis and a tritrichomonad protist both secreted succinate as a metabolite. In vivo sensing of the tritrichomonad required SUCNR1, whereas N. brasiliensis was SUCNR1 independent. These findings define a paradigm wherein tuft cells monitor microbial metabolites to initiate type 2 immunity and suggest the existence of other sensing pathways triggering the response to helminths.

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

  • HIF-1α expression is increased in synovial joints of rheumatoid arthritis patients.

    “Intriguingly, HIF-1α expression is also increased in synovial joints of RA patients7 suggesting that succinate may act in two ways to increase inflammation in RA: via SUCNR1 and HIF-1α.”
  • Inhibitors of α-KGDDs are often non-specific, hitting multiple isoforms or α-KGDD family members, such as DMOG acting on TETs but also PHDs.

    “Inhibitors of α-KGDDs are often non-specific, either hitting multiple isoforms or a-KGDD family members, such as dimethyloxaloylglycine (DMOG) acting on TETs but also PHDs [7].”

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.
