furin cleavage site is key to sars-cov-2 pathogenesis
by removing the furin cleavage site, we demonstrate the importance of this insertion to sars-cov-2 replication and pathogenesis.", "together, these results demonstrate a critical role for the furin cleavage site insertion in sars-cov-2 replication and pathogenesis.")
