In silico predictions combined with in vitro, in vivo and in situ observations collectively suggest that mouse adaptation of the SARS-CoV-2 virus requires an aromatic substitution in position 501 or position 498 (but not both) of the spike protein’s receptor binding domain. This effect could be enhanced by mutations in positions 417, 484, and 493 (especially K417N, E484K, Q493K and Q493R), and to a lesser extent by mutations in positions 486 and 499 (such as F486L and P499T). Such enhancements…

Common Laboratory Mice Are Susceptible to Infection with the SARS-CoV-2 Beta Variant
It is shown that the SARS-CoV-2 beta variant attains infectibility to BALB/c mice and causes pulmonary changes within 2–3 days post infection, consistent with results seen in other murine models of COVID-19, at a reasonable virus dose.


Characterization and structural basis of a lethal mouse-adapted SARS-CoV-2
A mouse adapted SARS-CoV-2 strain that harbored specific amino acid substitutions in the RBD of S protein showed 100% mortality in aged, male BALB/c mice is generated and the molecular mechanism for the rapid adaption and evolution of SARS, in human and animals is unveiled.
Experimental and in silico evidence suggests vaccines are unlikely to be affected by D614G mutation in SARS-CoV-2 spike protein
The ‘D614G’ mutation (Aspartate-to-Glycine change at position 614) of the SARS-CoV-2 spike protein has been speculated to adversely affect the efficacy of most vaccines and countermeasures that
The B1.351 and P.1 variants extend SARS-CoV-2 host range to mice
It is shown that unlike the initial virus, VOCs are able to infect common laboratory mice, replicating to high titers in the lungs, and abrogation of the species barrier raises the possibility of wild rodent secondary reservoirs and provides new experimental models to study disease pathophysiology and countermeasures.
Animal Models of COVID-19. I. Comparative Virology and Disease Pathogenesis
Abstract The Coronavirus Disease 2019 (COVID-19) pandemic has fueled unprecedented development of animal models to understand disease pathogenesis, test therapeutics, and support vaccine development.
Structural impact on SARS-CoV-2 spike protein by D614G substitution
Cryo-EM structures of a full-length S trimer carrying G614 are reported, which adopts three distinct prefusion conformations differing primarily by the position of one receptor-binding domain (RBD), which extend the understanding of viral entry and suggest an improved immunogen for vaccine development.
In silico comparison of SARS-CoV-2 spike protein-ACE2 binding affinities across species and implications for virus origin
It is shown that the earliest known SARS-CoV-2 isolates were surprisingly well adapted to bind strongly to human ACE2, helping explain its efficient human to human respiratory transmission.
The N501Y mutation in SARS-CoV-2 spike leads to morbidity in obese and aged mice and is neutralized by convalescent and post-vaccination human sera
It is shown that human convalescent and post vaccination sera can neutralize the newly emerging N501Y virus variant with similar efficiency as that of the reference USA-WA1/2020 virus, suggesting that current SARS-CoV-2 vaccines will protect against the 20B/501Y.V1 strain.
Q493K and Q498H substitutions in Spike promote adaptation of SARS-CoV-2 in mice
The dynamics of the adaptive mutations in SARS-CoV-2 were characterized and it was found that the Q493K and Q498H mutations in the RBD of WBP-1 enhanced its interactive affinities with mACE2.
SARS-CoV-2 infection, neuropathogenesis and transmission among deer mice: Implications for spillback to New World rodents
It is determined that deer mice are a suitable animal model for the study of SARS-CoV-2 respiratory disease and neuropathogenesis, and that they have the potential to serve as secondary reservoir hosts in North America.
A mouse-adapted model of SARS-CoV-2 to test COVID-19 countermeasures
A model in mouse using a species-adapted virus recapitulates features of SARS-CoV-2 infection and age-related disease pathogenesis in humans, and provides a model system for rapid evaluation of medical countermeasures against coronavirus disease 2019 (COVID-19).
