Guanylate binding proteins promote caspase-11–dependent pyroptosis in response to cytoplasmic LPS
Open accessAbstract
Significance: A major component of the cell envelope of Gram-negative bacteria is LPS, also known as endotoxin. LPS produced during bacterial infections triggers inflammation, which can lead to septic shock and death. Our immune system can recognize LPS both outside and inside of cells. The recognition of extracellular and vacuolar LPS by LPS binding proteins is well described, but little is known about the recognition of cytoplasmic LPS. Here, we show that cytoplasmic LPS derived from the intracellular bacterial pathogen Legionella activated a proinflammatory immune response. We further identified host guanylate binding proteins as critical mediators of immunity triggered by cytoplasmic LPS. These findings are likely to advance our understanding of how cells can sense intracellular LPS.

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.
