Metabolic endotoxemia is dictated by the type of lipopolysaccharide
Open accessAbstract
Abstract Lipopolysaccharides (LPS) can promote metabolic endotoxemia, which is considered inflammatory and metabolically detrimental based on Toll-like receptor (TLR)4 agonists such as Escherichia coli -derived LPS. LPS from certain bacteria antagonize TLR4 yet contribute to endotoxemia measured by Endotoxin Units (EU). We found that E. coli LPS impaired gut barrier function and worsened glycemic control in mice, but equal doses of LPS from other bacteria did not. Matching the LPS dose from R. sphaeroides and E. coli by EU revealed that only E. coli LPS promoted dysglycemia, adipose inflammation, delayed intestinal glucose absorption, and augmented insulin and GLP-1 secretion. Metabolically beneficial endotoxemia promoted by R. sphaeroides LPS counteracted dysglycemia caused by an equal dose of E. coli LPS and promoted insulin sensitivity in obese mice. The concept of metabolic endotoxemia should be expanded beyond LPS load (EU) to include LPS characteristics, where the balance of deleterious and beneficial endotoxemia regulates host metabolism. Highlights Type of LPS dictates gut barrier function, inflammation, insulin, GLP-1, intestinal glucose absorption and blood glucose Endotoxin Units (EU) do not reflect how LPS influences blood glucose or hormones LPS derived from certain types of bacteria are insulin sensitizers R. sphaeroides LPS promotes metabolically beneficial endotoxemia LPS characteristics dictate metabolically beneficial versus deleterious endotoxemia

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.
