Abstract

Mammalian airways protect themselves from bacterial infection by using multiple defense mechanisms including antimicrobial peptides, mucociliary clearance, and phagocytic cells. We asked whether airways might also target a key bacterial cell-cell communication system, quorum-sensing. The opportunistic pathogen Pseudomonas aeruginosa uses two quorum-sensing molecules, N -(3-oxododecanoyl)- l -homoserine lactone (3OC12-HSL) and N -butanoyl- l -homoserine lactone (C4-HSL), to control production of extracellular virulence factors and biofilm formation. We found that differentiated human airway epithelia inactivated 3OC12-HSL. Inactivation was selective for acyl-HSLs with certain acyl side chains, and C4-HSL was not inactivated. In addition, the capacity for inactivation varied widely in different cell types. 3OC12-HSL was inactivated by a cell-associated activity rather than a secreted factor. These data suggest that the ability of human airway epithelia to inactivate quorum-sensing signal molecules could play a role in the innate defense against bacterial infection.

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.
