Chinese scientists say they have identified a pair of antibodies that neutralize coronary SARS-CoV-2. Antibodies were isolated from a patient who contracted Covid-19 disease.
Antibodies bind to the protruding coronary spike and therefore block their ability to bind to ACE2 receptors (the angiotensin-converting enzyme) in human cells. In this way, the virus “door” penetrates the cells. The first tests of the two antibodies in mice reduced the viral load, indicating that the antibodies could provide therapeutic benefits.
Researchers led by Dr. Jan Wu, from the Department of Microbiology, Beijing Faculty of Basic Medical Sciences, who published the study in the journal Science, found that the two antibodies B38 and H4 can simultaneously bind in different parts of the body. coronary protein tip, resulting in a stronger neutralizing effect than if only one antibody were bound to the virus. This also means, according to the researchers, that if the protruding protein mutates at some point in the future, with the result that one antibody can no longer bind, the other antibody will likely continue to exert its neutralizing effect.
Chinese scientists reported that a “cocktail” containing both antibodies will provide immediate therapeutic benefit to patients with Covid-19.
