Abstract

Ironing out the details of mucosal healing: Anemia is a frequent complication of disorders such as inflammatory bowel disease, occurring in part as a result of increased bleeding into the intestine. Bessman et al. show that the peptide hormone hepcidin, which regulates systemic iron homeostasis, is required for intestinal repair in a mouse model of inflammatory bowel disease (see the Perspective by Rescigno). This effect was independent of hepatocyte-produced hepcidin and systemic iron levels. Instead, production of hepcidin by conventional dendritic cells was necessary and sufficient to promote local iron sequestration by macrophages, which in turn modulated the makeup of the gut microbiota to one with a more beneficial distribution of species.

  • Absence of local hepcidin production or insensitivity of macrophage ferroportin to hepcidin results in higher local extracellular iron concentrations, affecting the growth of luminal and tissue-infiltrating bacteria and worsening DSS-induced colitis.

    “Absence of local hepcidin production or insensitivity of macrophage ferroportin to hepcidin is thought to result in higher local extracellular iron concentrations, affecting the growth of luminal and tissue-infiltrating bacteria and worsening DSS-induced colitis.”
  • In a mouse model of colitis, the hepcidin-ferroportin interaction in the intestine is important for mucosal healing.

    “In a mouse model of colitis, the hepcidin-ferroportin interaction in the intestine was shown to be important for mucosal healing [49].”
  • Favorable taxa had more genes for polysaccharide deacetylation, iron transport, and iron-induced ROS production.

    “Within favorable taxa, we identified increased abundance of genes related to polysaccharide deacetylation known to play a role in immune evasion42, as well as iron transport and iron-induced production of reactive oxygen species ROS, which affect mucosal healing43.”
  • In experimental murine dextran sodium sulphate-driven colitis, HAMP production by dendritic cells was proposed to drive local iron sequestration in colonic myeloid cells, limiting increases in free iron driven by loss of barrier integrity and tissue damage.

    “Recently, in an experimental murine dextran sodium sulphate‐driven colitis, HAMP production by dendritic cells was proposed to drive local iron sequestration in colonic myeloid cells, limiting increases in free iron driven by loss of barrier integrity and tissue damage.”

  • Failure to sequester iron locally resulted in dysbiosis, increased microbial translocation across the mucosa, persistent gut inflammation and failure to recover weight.

    “Failure to sequester iron locally resulted in dysbiosis, increased microbial translocation across the mucosa, persistent gut inflammation and failure to recover weight 107 (Fig. 2).”

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.
