Interaction Information:

Comment SARS-CoV can use the endosomal cysteine proteases cathepsin B and L (CatB/L) and the serineprotease TMPRSS2 for S protein priming in cell lines, and inhibition of both proteases is required for robust blockade of viral entry. However, only TMPRSS2 activity is essential for viral spread and pathogenesis in the infected host whereas CatB/L activity is dispensable. This study shows that SARS-CoV-2 can use TMPRSS2 for S protein priming and camostat mesylate, an inhibitor of TMPRSS2, blocks SARS-CoV-2 infection of lung cells.
