COL1A1 and infection: Survival of Col1a1-K18-hACE2 KI mice after infection with a highly pathogenic variant could provide a model that better mimics human disease progression and thus could be instrumental for the study of specific disease aspects such as the consequences of inflammation (including loss of taste or smell) of post-COVID conditions (PCC) or sequelae, long-term effects of drug therapies, and susceptibility to reinfection.
