Abstract

Decreased expression of the Nlrp3 protein is associated with susceptibility to Crohn's disease. However, the role of Nlrp3 in colitis has not been characterized. Nlrp3 interacts with the adaptor protein ASC to activate caspase-1 in inflammasomes, which are protein complexes responsible for the maturation and secretion of interleukin-1beta (IL-1beta) and IL-18. Here, we showed that mice deficient for Nlrp3 or ASC and caspase-1 were highly susceptible to dextran sodium sulfate (DSS)-induced colitis. Defective inflammasome activation led to loss of epithelial integrity, resulting in systemic dispersion of commensal bacteria, massive leukocyte infiltration, and increased chemokine production in the colon. This process was a consequence of a decrease in IL-18 in mice lacking components of the Nlrp3 inflammasome, resulting in higher mortality rates. Thus, the Nlrp3 inflammasome is critically involved in the maintenance of intestinal homeostasis and protection against colitis.

  • The inflammasome can strongly affect gut microbiota composition, as deletion of inflammasome components was associated with loss of epithelial integrity and gut inflammation associated with dysbiosis and bacteremia.

    “The inflammasome can indeed strongly affect gut microbiota composition as deletion of inflammasome components was associated with loss of epithelial integrity and gut inflammation associated with dysbiosis and bacteremia [292].”
  • Commensal bacteria and their bioproducts induce inflammasome activation and IL-18 production in the gut, which prevents intestinal barrier disruption and dysbiosis.

    “Commensal bacteria and their bioproducts induce inflammasomes activation and IL-18 production in the gut, which, in turn, prevents intestinal barrier disruption and dysbiosis [121,124,131,132,133].”

  • Dysbiosis has been observed in mice deficient for inflammasome components including NLRP6, ASC, caspase-1, and IL-18.

    “Dysbiosis has been observed in mice deficient for inflammasomes components, including NLRP6, ASC, caspase-1, and IL-18 [131,132,133,134].”

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.
