Virus that causes COVID-19 can find alternate route to infect cells

Now, researchers at Washington University School of Medicine in St. Louis have found that a single mutation gives SARS-CoV-2 the ability to enter cells through another route – one that does not require ACE2. The ability to use an alternative entry pathway opens up the possibility of evading COVID-19 antibodies or vaccines, but the researchers did not find evidence of such evasion. However, the discovery does show that the virus can change in unexpected ways and find new ways to cause infection. The study is published June 23 in Cell Reports.
