The study's authors - David Wiesler, a biochemist at the University of Washington School of Medicine, and David Corti, a researcher at the Swiss research company Humabs Biomed SA - have isolated antibodies that block coronavirus, writes Nature.

The body of a person who had SARS-CoV atypical pneumonia in 2003 developed monoclonal antibodies during infection, and subsequently they remained in the memory of his immune system. So, the S309 antibody, which was isolated by biochemists, can infect areas of the S-protein (or protein spikes) not only of the SARS-CoV virus, but also of SARS-CoV-2, which causes COVID-19. It is because of the appearance of these spikes, resembling a crown, that the name "coronavirus" originated.

When parts of the S-protein are destroyed, the virus can no longer penetrate into the cell. Therefore, people who have previously suffered from acute respiratory syndrome may be immune to coronavirus infection.

A mixture of antibodies like S309 can be used not only to treat severe forms of COVID-19, but also to prevent infection, the researchers note.
