Abstract

Multiple lung pathogens such as chemical agents, H5N1 avian flu, or SARS cause high lethality due to acute respiratory distress syndrome. Here we report that Toll-like receptor 4 (TLR4) mutant mice display natural resistance to acid-induced acute lung injury (ALI). We show that TLR4-TRIF-TRAF6 signaling is a key disease pathway that controls the severity of ALI. The oxidized phospholipid (OxPL) OxPAPC was identified to induce lung injury and cytokine production by lung macrophages via TLR4-TRIF. We observed OxPL production in the lungs of humans and animals infected with SARS, Anthrax, or H5N1. Pulmonary challenge with an inactivated H5N1 avian influenza virus rapidly induces ALI and OxPL formation in mice. Loss of TLR4 or TRIF expression protects mice from H5N1-induced ALI. Moreover, deletion of ncf1, which controls ROS production, improves the severity of H5N1-mediated ALI. Our data identify oxidative stress and innate immunity as key lung injury pathways that control the severity of ALI.

  • Macrophage activation via TLR4, a type of PRR, is involved in gastric acid-induced ARDS and mouse ARDS models induced by SARS-CoV-1 or influenza virus H5N1.

    “Macrophage activation via TLR4, a type of PRR, is also involved in gastric acid-induced ARDS and mouse ARDS models induced by SARS-CoV-1 or influenza virus H5N1 (355).”

    From IL-6 in inflammation, autoimmunity and cancer (2021) · cites this paper as [355]

    The Results sections on acid-induced ALI and inactivated H5N1-induced ALI show TLR4-dependent lung injury and macrophage cytokine responses in mice. For SARS, the paper reports oxidized phospholipids in patients’ lungs, but does not establish TLR4-mediated macrophage activation in a SARS-induced mouse ARDS model. The H5N1 experiment used inactivated virus. Page numbers were not available in our copy. (LLM, conf=0.88)

  • Endogenous products such as oxidized phospholipids and matrix breakdown products also drive inflammation through TLR4 and probably other TLRs, providing a mechanism for perpetuating inflammation when microbial products are being cleared from the lungs.

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.
