Abstract

In response to enteric pathogens, the inflamed intestine produces antimicrobial proteins, a process mediated by the cytokines IL-17 and IL-22. Salmonella enterica serotype Typhimurium thrives in the inflamed intestinal environment, suggesting that the pathogen is resistant to antimicrobials it encounters in the intestinal lumen. However, the identity of these antimicrobials and corresponding bacterial resistance mechanisms remain unknown. Here, we report that enteric infection of rhesus macaques and mice with S. Typhimurium resulted in marked Il-17- and IL-22-dependent intestinal epithelial induction and luminal accumulation of lipocalin-2, an antimicrobial protein that prevents bacterial iron acquisition. Resistance to lipocalin-2, mediated by the iroBCDE iroN locus, conferred a competitive advantage to the bacterium in colonizing the inflamed intestine of wild-type but not of lipocalin-2-deficient mice. Thus, resistance to lipocalin-2 defines a specific adaptation of S. Typhimurium for growth in the inflamed intestine.

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

  • Salmochelins serve as a competitive advantage for Salmonella to disrupt colonization resistance exerted by commensal E. coli, opening the route for intestinal infection.

    “The latter serve as competitive advantage for Salmonella to disrupt the colonization resistance exerted by commensal E. coli, opening the route for intestinal infection (Raffatellu et al., 2009).”

    From Iron in infection and immunity (2020) · cites this paper as Raffatellu et al., 2009

    The Discussion (page unavailable) says salmochelin confers lipocalin-2 resistance, which benefits S. Typhimurium in the inflamed mouse cecum; it also notes that lipocalin-2 inhibits some commensal E. coli. It does not show salmochelins disrupting colonization resistance exerted by commensal E. coli or opening the route for initial intestinal infection. (LLM, conf=0.86)

  • Bacillus anthracis and Salmonella Typhimurium produce modified stealth siderophores that are not bound by siderocalin.

    “For instance, this strategy is used by B. anthracis and Salmonella Typhimurium, both of which produce modified siderophores that are not bound by siderocalin (Abergel et al., 2006; Raffatellu et al., 2009).”

  • S. Typhimurium's ability to avoid lipocalin-2-mediated defenses provides a selective advantage during inflammation.

    “The ability of S. Typhimurium to avoid lipocalin-2 mediated defenses provides a selective advantage during inflammation (Raffatellu et al., 2009).”

  • During Salmonella-induced inflammation, the host releases lactoferrin to sequester iron and lipocalin-2 to bind bacterial siderophores and undermine bacterial iron acquisition.

  • LCN2 is an infection-induced host antimicrobial that blocks bacterial uptake of iron-loaded siderophores.

    “Lipocalin 2 (LCN2) is a host antimicrobial factor induced upon infection that inhibits bacterial uptake of iron-laden siderophores (Flo et al., 2004, Raffatellu et al., 2009, Deriu et al., 2013).”

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.
