Scientists the SCRIPPS research Institute in the US found in the blood of recovered from COVID-19 patients antibodies that provide powerful protection against the coronavirus. This was reported in an article published in the journal Science.
The researchers took blood samples from people who have had light and heavy forms of the disease. In the course of the experiment, the specialists used the test cells that synthesize the receptor ACE2 interacts with the virus before penetration into the cell. The researchers tested whether antibodies containing the blood contact with the virus and block the infection process.
Experts have identified over a thousand different of antibody-producing immune cells called b-cells, each of which synthesized a particular type of antibody against SARS-CoV-2. When the sequence of the genes encoding antibodies, found, scientists were able to synthesize them in the laboratory. The screening results showed that some antibodies even in small amounts can effectively block the virus, preventing infection of test cells.
According to scientists, if further security tests on animals and clinical trials involving humans is successful, the antibodies can be used as a therapeutic agent in January of next year.
