Intracellular Lipopolysaccharide Sensing as a Potential Therapeutic Target for Sepsis

Pfalzgraff, Anja, Weindl, Günther·2019·Trends in Pharmacological Sciences

Abstract

Lipopolysaccharide (LPS) sensing in the cytosol by the noncanonical inflammasome leads to pyroptosis and NLRP3 inflammasome activation. This mechanism may be more critical for sepsis development than recognition of LPS by Toll-like receptor 4. LPS is directly binding to its intracellular receptor caspase-4/5/11, mediated by outer membrane vesicles and guanylate-binding proteins that deliver LPS to the cytosol and mediate access of caspases to LPS. Caspase-11-dependent cleavage of gasdermin D is discussed as a link between LPS-induced activation of caspases and pyroptosis or NLRP3 inflammasome activation. Finally, we highlight recently described inhibitors of cytosolic LPS-triggered noncanonical inflammasome activation that might be considered as potential drugs for the treatment of sepsis.

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.
