Abstract:The use of soluble recombinant ACE2 (rACE2) as a decoy capable of blocking SARS-CoV-2 entry into cells has been envisaged as a therapeutic strategy to reduce viral loads in patients suffering from severe COVID-19. We engineered a novel form of rACE2, fused to the Epstein-Barr virus (EBV) antigen P18F3 (rACE2-P18F3), to reorient a pre-existing humoral response towards EBV against SARS-CoV-2 particles. Recombinant ACE2-P18F3 was able to bind to the SARS-CoV-2 spike protein, neutralized viral entry into cells and… Show more
