Abstract

Pneumonia is a leading cause of death worldwide. Staphylococcal aureus can be a cause of severe pneumonia alone or a common pathogen in secondary pneumonia following influenza. Recently, we reported that preceding influenza attenuated the Type 17 pathway, increasing the lung's susceptibility to secondary infection. IL-1β is known to regulate host defense, including playing a role in Th17 polarization. We examined whether IL-1β signaling is required for S. aureus host defense and whether influenza infection impacted S. aureus-induced IL-1β production and subsequent Type 17 pathway activation. Mice were challenged with S. aureus (USA 300), with or without preceding Influenza A/PR/8/34 H1N1 infection. IL-1R1(-/-) mice had significantly higher S. aureus burden, increased mortality, and decreased Type 17 pathway activation following S. aureus challenge. Coinfected mice had significantly decreased IL-1β production versus S. aureus infection alone at early time points following bacterial challenge. Preceding influenza did not attenuate S. aureus-induced inflammasome activation, but there was early suppression of NF-κB activation, suggesting an inhibition of NF-κB-dependent transcription of pro-IL-1β. Furthermore, overexpression of IL-1β in influenza and S. aureus-coinfected mice rescued the induction of IL-17 and IL-22 by S. aureus and improved bacterial clearance. Finally, exogenous IL-1β did not significantly rescue S. aureus host defense during coinfection in IL-17RA(-/-) mice or in mice in which IL-17 and IL-22 activity were blocked. These data reveal a novel mechanism by which Influenza A inhibits S. aureus-induced IL-1β production, resulting in attenuation of Type 17 immunity and increased susceptibility to bacterial infection.

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

  • Influenza A infection significantly decreases IL-1β production.

  • IL-1β plays a role in Th17 polarization, so decreased IL-1β further hinders Th17 immunity.

    “IL-1β has been shown to play a role in Th17 polarization, therefore further hindering this pathway of immunity (Robinson 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.
