Abstract

Background: Histamine is an important immunomodulator influencing both the innate and adaptive immune system. Certain host cells express the histidine decarboxylase enzyme (HDC), which is responsible for catalysing the decarboxylation of histidine to histamine. We and others have shown that bacterial strains can also express HDC and secrete histamine; however, the influence of bacterial‐derived histamine on the host immune responses distant to the gut is unclear. Methods: The Escherichia coli BL 21 (E coli BL 21) strain was genetically modified to express the Morganella morganii (M morganii)‐derived HDC gene (E coli BL 21_ HTW). E coli BL 21 and E coli BL 21_ HTW were gavaged to ovalbumin (OVA) sensitized and challenged mice to investigate the effect of bacterial‐derived histamine on lung inflammatory responses. Results: Oral administration of E coli BL 21_ HTW, which is able to secrete histamine, to wild‐type mice reduced lung eosinophilia and suppressed ex vivo OVA‐stimulated cytokine secretion from lung cells in the OVA respiratory inflammation mouse model. In histamine receptor 2 (H2R)‐deficient mice, administration of histamine‐secreting bacteria also reduced inflammatory cell numbers in bronchoalveolar lavage (BAL). However, the suppressive effect of bacterial‐derived histamine on BAL inflammation was lost in HDC‐deficient mice. This loss of activity was associated with increased expression of histamine degrading enzymes and reduced histamine receptor expression. Conclusion: Histamine secretion from bacteria within the gut can have immunological consequences at distant mucosal sites, such as within the lung. These effects are influenced by host histamine receptor expression and the expression of histamine degrading enzymes.

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

  • Mice treated with histamine-secreting E. coli BL21_HTW showed decreased lung eosinophilia and depressed OVA-sensitized cytokine secretion from lung cells in an airway inflammation model.

    “mice treated with E. coli BL21_HTW, bacteria that secrete histamine after genetic modification, showed decreased lung eosinophilia and depressed ovalbumin (OVA)-sensitized cytokine secretion from lung cells in an airway inflammation model (45).”

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.
