#Molecular basis of #pathogenicity of recently emerged #FCoV23 #coronavirus, BioRxIV: https://www.biorxiv.org/content/10.1101/2024.08.25.607996v1
FCoV-23 is a recently emerged, highly pathogenic #recombinant coronavirus responsible for a widespread #outbreak of #feline infectious #peritonitis (FIP) likely linked to in-host viral evolution. Here, we report cryoEM structures of two FCoV-23 spike (S) isoforms explaining that the in-host loss of domain 0 observed in clinical samples enhances entry into cells ...
