KRT18 and encephalitis: The K18-hACE2 mice demonstrate that SARS-CoV-2 neuroinvasion and encephalitis is associated with mortality in these mice.10 No rapid axonal transport of SARS-CoV-2 to the brain has been demonstrated in the hamster model during the first 2 weeks after infection.30 In our present study, we observed SARS-CoV-2 protein not only in neurons but also in astrocytes and microglia of rhesus monkeys.
