Abstract

Although more than 100 people have been infected by H5N1 influenza A viruses, human-to-human transmission is rare. What are the molecular barriers limiting human-to-human transmission? Here we demonstrate an anatomical difference in the distribution in the human airway of the different binding molecules preferred by the avian and human influenza viruses. The respective molecules are sialic acid linked to galactose by an alpha-2,3 linkage (SAalpha2,3Gal) and by an alpha-2,6 linkage (SAalpha2,6Gal). Our findings may provide a rational explanation for why H5N1 viruses at present rarely infect and spread between humans although they can replicate efficiently in the lungs.

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

  • Seasonal influenza A virus binds to α2-6 sialylated glycans on cells in the upper respiratory tract, whereas highly pathogenic avian H5N1 binds to α2-3 sialylated glycans on type 2 pneumocytes lining lung alveoli.

    “traditionally seasonal influenza A virus binds to α2-6 sialylated glycans on cells in the upper respiratory tract whereas the highly pathogenic avian H5N1 strain binds to α2-3 sialylated glycans on type 2 pneumocytes lining lung alveoli (Shinya et al., 2006).”

  • In severe infections affecting the deep tissues of the respiratory tract, it is probable that the immunological cascade that takes place directly in the deep tissues is crucial to immunopathology rather than what can be measured as a 'spillover' in the peripheral blood.

    “For instance, in severe infections affecting the deep tissues of the respiratory tract (as has been described in avian influenza or severe primary influenza virus infections), it is probable that it is the immunological cascade that takes place directly in the deep tissues that is crucial to immunopathology rather than what can be measured as a “spillover” in the peripheral blood (28,82,128).”

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.
