Rhinovirus enhances various bacterial adhesions to nasal epithelial cells simultaneously

Wang, Jong Hwan, Kwon, Hyun Ja, Jang, Yong Ju·2009·The Laryngoscope

Abstract

OBJECTIVES/HYPOTHESIS: Viral upper respiratory tract infections are often followed by secondary bacterial infections in the form of acute rhinosinusitis. We investigate the effect of rhinovirus infection on the expression of cell adhesion molecules and bacterial adherence to primary human nasal epithelial cells. METHODS: Cells were infected with rhinovirus serotype 16 (RV-16), and then Staphylococcus aureus, Streptococcus pneumoniae, or Hemophilus influenzae were added to the culture. Rhinovirus-induced expression of fibronectin, platelet-activating factor receptor, and carcinoembryonic antigen-related cell adhesion molecule, was assayed by confocal microscopy, real-time polymerase chain reaction, and Western blot analysis. Bacterial adhesion to cells was assessed by confocal microscopy and the fluorescence intensity of adherent bacteria was analyzed using Image-Pro Plus 5.1 (Media Cybernetics, Inc., Bethesda, MD). RESULTS: RV-16 infection significantly increased the gene and protein expression of fibronectin, platelet-activating factor receptor, and carcinoembryonic antigen-related cell adhesion molecule in nasal epithelial cells. Compared with rhinovirus-uninfected control cells, the adhesion of S. aureus, S. pneumoniae, and H. influenzae increased significantly to 2.53-fold, 1.51-fold, and 2.74-fold of control levels, respectively, in rhinovirus-infected nasal epithelial cells. CONCLUSIONS: These findings suggest that increased expression of host cell adhesion molecules may be the mechanism accounting for the increase in susceptibility to bacterial rhinosinusitis associated with rhinovirus-induced upper respiratory infections.

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

  • In experimental in vitro models, viral infections increase the colonization rates of various bacteria in the URT, including S. pneumoniae and H. influenzae.

    “In experimental in vitro models, viral infections increase the colonization rates of various bacteria in the URT (90–95), including S. pneumoniae and H. influenzae (86–88).”
  • Given the effects of viruses on enhancing bacterial adherence to the epithelium, multiple studies of human subjects as well as in animal models have shown that viral infections are associated with increased colonization by potentially pathogenic bacteria.

    “Given the effects of viruses on enhancing bacterial adherence to the epithelium (86–88), it is perhaps not surprising that multiple studies of human subjects as well as in animal models have shown that viral infections are associated with increased colonization by potentially pathogenic bacteria”
  • Epithelium-derived cytokines and chemokines, by increasing cellular recruitment into infected airways, are believed to be responsible for damaging both infected and uninfected areas of the lung.

    “Epithelium-derived cytokines and chemokines, by increasing cellular recruitment into infected airways, are believed to be responsible for damaging both infected and uninfected areas of the lung (117, 305).”

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.
