Cathepsin inhibitors do not attenuate virus–cell interaction. TE671/mCAT1 (A) were treated with DMSO (upper panel) or CA-074Me (25 μM) (lower panel). NIH3T3 cells (B) were treated with DMSO (upper panel), CA-074Me (40 μM) (middle panel), or CLIK148 (1000 μM) (lower panel). Black area indicates cells suspended with culture supernatant of TELCeB6 cells that do not express any Env proteins. Open area indicates cells suspended with culture supernatant of the Eco-MLV Env-expressing TELCeB6 cells.
