ACE2 and infection: We also quantified the relative expression of BSG/CD147, ACE2 (given its involvement in SARS-CoV-2 binding and infection of many cell types) (Hoffmann et al., 2020; Shang et al., 2020a; Yanwei Li et al., 2020; Shang et al., 2020b), as well as cell surface protease TMPRSS2 (Wysocki et al., 2021) and endosomal Cathepsin L (CTSL) in podocytes infected with SARS-CoV-2 for 72 h using different MOIs (Figure 3F).
