SARS-CoV-2 infection of human ACE2-transgenic mice causes severe lung inflammation and impaired function #MMPMID32839612Winkler ES; Bailey AL; Kafai NM; Nair S; McCune BT; Yu J; Fox JM; Chen RE; Earnest JT; Keeler SP; Ritter JH; Kang LI; Dort S; Robichaud A; Head R; Holtzman MJ; Diamond MSNat Immunol 2020[Nov]; 21 (11): 1327-1335 PMID32839612show ga
Although animal models have been evaluated for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, none have fully recapitulated the lung disease phenotypes seen in humans who have been hospitalized. Here, we evaluate transgenic mice expressing the human angiotensin I-converting enzyme 2 (ACE2) receptor driven by the cytokeratin-18 (K18) gene promoter (K18-hACE2) as a model of SARS-CoV-2 infection. Intranasal inoculation of SARS-CoV-2 in K18-hACE2 mice results in high levels of viral infection in lungs, with spread to other organs. A decline in pulmonary function occurs 4 days after peak viral titer and correlates with infiltration of monocytes, neutrophils and activated T cells. SARS-CoV-2-infected lung tissues show a massively upregulated innate immune response with signatures of nuclear factor-kappaB-dependent, type I and II interferon signaling, and leukocyte activation pathways. Thus, the K18-hACE2 model of SARS-CoV-2 infection shares many features of severe COVID-19 infection and can be used to define the basis of lung disease and test immune and antiviral-based countermeasures.|Angiotensin-Converting Enzyme 2[MESH]|Animals[MESH]|Betacoronavirus/*immunology[MESH]|COVID-19[MESH]|Chlorocebus aethiops[MESH]|Coronavirus Infections/immunology/*pathology[MESH]|Disease Models, Animal[MESH]|Female[MESH]|Humans[MESH]|Immunity, Innate/*immunology[MESH]|Interferon Type I/immunology[MESH]|Interferon-gamma/immunology[MESH]|Keratin-18/genetics[MESH]|Leukocytes/immunology[MESH]|Lymphocyte Activation/immunology[MESH]|Male[MESH]|Mice[MESH]|Mice, Transgenic[MESH]|Monocytes/immunology[MESH]|NF-kappa B/immunology[MESH]|Neutrophil Infiltration/immunology[MESH]|Neutrophils/immunology[MESH]|Pandemics[MESH]|Peptidyl-Dipeptidase A/*genetics[MESH]|Pneumonia, Viral/immunology/*pathology[MESH]|Pneumonia/genetics/*pathology/virology[MESH]|Promoter Regions, Genetic/genetics[MESH]|SARS-CoV-2[MESH]|T-Lymphocytes/immunology[MESH]|Vero Cells[MESH]
