New cases of COVID-19 infection were detected in 17 cities and regions of the Rostov region


Rostov Region, July 13, 2020. DON24.RU. Nanoantibodies that prevent the new coronavirus from entering cells have created British molecular biologists. Writes about it TASS with reference to the scientific journal Nature.

“The technology for growing nanoantibodies allows us to create molecules in real time that can very effectively neutralize new viral threats. We hope that the antibodies H11-H4 and H11-D4 will become a component of drugs that will save the lives of severely ill patients or help passive immunity to form, ”the expert’s source quotes.

Nanoantibodies consist of only one block, which is part of a complete antibody molecule. Nanoantibodies are more stable, they better tolerate heat and aggressive chemical environments, including when they enter the stomach and intestines.

There are no nanoantibodies in the human body and many animals, but scientists found them in samples of the biomaterials of camels, alpacas, llamas and sharks. To create universal mini-antibodies, immune cells of llamas were used. As it turned out, they can neutralize almost all strains of swine flu, as well as combine with the part of the membrane of the new coronavirus, which is responsible for its penetration into the cell. After the “improvement” of the nanoantibodies it became clear – they are able to block a new coronavirus.

“Such drugs, as scientists conclude, can be used not only for the treatment of severe forms of coronavirus, but also for the prevention of this disease. The fact is that if you introduce H11-H4 and H11-D4 into the blood of healthy people, they will prevent the virus from entering human cells and start those processes that are associated with the development of coronavirus infection, ”the source writes.

WHO previously reported who is least likely to become infected with COVID-19.
