Abstract

The severe acute respiratory syndrome (SARS), caused by a novel coronavirus (SARS-CoV), resulted in substantial morbidity, mortality, and economic losses during the 2003 epidemic. While SARS-CoV infection has not recurred to a significant extent since 2003, it still remains a potential threat. Understanding of SARS and development of therapeutic approaches have been hampered by the absence of an animal model that mimics the human disease and is reproducible. Here we show that transgenic mice that express the SARS-CoV receptor (human angiotensin-converting enzyme 2 [hACE2]) in airway and other epithelia develop a rapidly lethal infection after intranasal inoculation with a human strain of the virus. Infection begins in airway epithelia, with subsequent alveolar involvement and extrapulmonary virus spread to the brain. Infection results in macrophage and lymphocyte infiltration in the lungs and upregulation of proinflammatory cytokines and chemokines in both the lung and the brain. This model of lethal infection with SARS-CoV should be useful for studies of pathogenesis and for the development of antiviral therapies.

  • Intranasal SARS-CoV-1 inoculation in K18-hACE2 mutant mice resulted in viral presence throughout the CNS, associated with local inflammatory mediators, respiratory dysfunction, and high mortality, with only mild lung infection.

    “Intranasal SARS-CoV-1 inoculation (80% homology to SARS-CoV-2) in K18-hACE2 mutant mice (with the human form of ACE-2) resulted in the viral presence throughout the CNS, and was associated with local inflammatory mediators, respiratory dysfunction, and high mortality, with only mild lung infection [171, 172].”
  • SARS-CoV, MERS-CoV, and HCoV-OCR43 were able to invade the murine CNS using the transcribrial route, infecting olfactory sensory neurons of the nasal cavity and passing to other neural cells, indicating that SARS-CoV-2 could use the same mechanism.

    “In fact, SARS-CoV, MERS-CoV, and HCoV-OCR43 were able to invade the murine CNS using the transcribrial route, infecting olfactory sensory neurons of nasal cavity, and passing to other neural cells, indicating that SARS-CoV-2 could use the same mechanism [24, 35–37].”

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.
