Recently, research on the COVID-19 virus has progressed very quickly. A large number of studies have found that the plasma of COVID-19 patients after recovery contains a large amount of antiviral antibodies, so the blood transfusion of these patients into new patients has a therapeutic effect.
The second edition of our country’s diagnosis and treatment plan also stated that the patient’s plasma can be transfused to heavier patients, thereby playing a therapeutic role, and this has been confirmed in clinical practice.
However, transfusion of plasma to COVID-19 patients has certain risks. For example, some COVID-19 patients may have an allergic reaction when they enter other people’s plasma; or some patients carry other substances that are different from their own bodies. Will cause new diseases …
These are some potential risks, so if the antibodies can be extracted from the plasma of these restorers and then treated with the patients, the specificity will be stronger and the theoretical side effects will be smaller.
Therefore, the scientists from the Third Hospital of Shenzhen and the research team of Tsinghua University jointly conducted a study. The research mainly focused on the extraction of specific antibodies in the plasma of patients cured by COVID-19 virus, and the specific antibodies were also successfully extracted. .
The research team studied the plasma of eight patients with COVID-19 and extracted a lot of antibodies. After in vitro experiments, they found that the binding rate of these antibodies to the COVID-19 virus is very high, and the binding rate can even reach 99%.
When these antibodies are combined with the COVID-19 virus, they can block the virus from binding to human lung epithelial cells and prevent the virus from invading human lung tissues. This also shows that the extraction of antibodies with these characteristics has a therapeutic effect on humans.
In addition, relevant personnel can manually prepare antibodies based on the characteristics of these extracted antibodies, so that there can be drugs to treat patients with COVID-19.
Therefore, the significance of this research is very important, and it is of great significance for the future diagnosis and treatment plans and the development of some technologies in the future.
