Angiotensin-converting enzyme 2-based mutant decoy effectively reduces COVID-19 in mice

Researchers engineered a mutant ACE2 decoy that effectively protected human lung epithelia from SARS-CoV-2 infection by competitively binding to its spike protein.

The tetrapeptide tuftsin effectively impairs the binding of SARS-CoV-2 S1 to ACE2

In their recent study posted to the preprint server bioRxiv*, the researchers from China have shown that tuftsin, a natural phagocytosis-stimulating peptide, can effectively impair the binding of SARS-CoV-2 spike S1 subunit to ACE2 receptor in a dose-dependent manner and therefore can be considered a potential drug against SARS-CoV-2 infection.

The use of mammalian cell surface display for rapid characterization of SARS-CoV-2 variants

A research group from the U.S. demonstrated the practicality of a spike display system in order to accelerate vaccine design, but also to swiftly appraise the effects of mutations in emerging strains of the SARS-CoV-2.

Optimal antibody combinations and Fc binding inhibit SARS-CoV-2 in vivo

A recent study by researchers at the University of North Carolina at Chapel Hill and The Rockefeller University and published on the preprint server bioRxiv in September 2020 shows that a combination of neutralizing antibodies with intact Fc effector function can effectively reduce the viral load and prevent infection.
