Researchers from the United States revealed an antibody that can fight various coronavirus infections – including SARS and COVID-19. Dedicated to the promising media against coronaviruses The article of scientists was published in the journal Science Translational Medicine.
Specialists from Duke and North Carolina Universities analyzed the blood samples of two patients. One of them has become infected with the original virus SARS-COV-1 17 years ago, another sled COVID-19. They managed to find more than 1.7 thousand antibodies. 50 were capable of contacting both SARS-COV-1 and SARS-COV-2. One of these cross-antibodies, DH1047, turned out to be particularly powerful – it can bind to many animal coronaviruses.
In the experiments on mice, the researchers showed that the antibody effectively neutralizes both SARS and COVID-19 and its various options. Also, the antibody turned out to be able to reduce the severity of diseases when introduced both before and after the disease. According to researchers, DH1047 is able to serve as a basis for universal vaccines against coronavirus in the future. “Perhaps the antibody can be applied against SARS-COV-3 or SARS-COV-4,” says one of the researchers, the University of North Carolina University David Martinez.
