Engineered decoys trap virus before it can enter cells
The new coronavirus enters cells by attaching to a protein on the cell membrane called the ACE2 receptor. Scientists have now developed a decoy version of ACE2 that lures the virus and traps it, preventing it from infecting human lung cells in test tubes. “We have engineered our ACE2 Trap to bind 100 to 1,000 times tighter to the virus than normal ACE2 that is on victim cells. This provides even more potent blockage that is comparable to neutralizing antibodies,” Dr. James Wells of the University of California
