Scientists have identified an antibody that can protect people from coronavirus, its variants and other types of coronavirus, and the antibody works DH1047 By binding to virus cells, neutralizing them and preventing them from multiplying, it is effective in preventing infection and helping to treat a person already infected with the Corona virus, according to the British newspaper, “Daily Mail”.
The research team at the University of North Carolina and Duke University said they had found a key piece that could help combat the current epidemic and future outbreaks of the virus.
“This antibody has the potential to be therapeutic for the current pandemic and could also be available to prevent future outbreaks,” Dr. Barton Hines, director of the Duke Institute for Human Vaccines and co-author of the study, said in a statement.
In a study published in the journal, the researchers identified Science Translational Medicine , more than 1,700 antibodies to the Corona virus.
Of this group, 50 cells have been identified that can be associated with both the coronavirus and the SARS virus SAR The virus that caused an outbreak in Asia in the early 2000s.
It was one of them, named DH1047 , especially effective, as it was able to bind to all kinds of viruses, both animal and human.
“This antibody binds to the coronavirus at a conserved site via many mutations and variations and as a result, it can eliminate a wide range of coronaviruses,” Hines said.
The antibody was tested on mice, and it was found that it was able to protect rodents from infection with corona after exposure to the virus. It was effective against all types of strains as well, including the highly infectious delta variant.
Other types of coronavirus that are believed to have the potential to infect humans have also been tested and neutralized by the antibody.
“The findings provide a model for the rational design of global vaccine strategies that are resistant to changes and provide broad protection against known and emerging coronaviruses,” said Dr. Ralph Barrick, professor of epidemiology at the University of North Carolina and co-author of the paper.
When testing the antibodies on already infected animals, they found it effective in reducing the severity of symptoms related to the lungs.
Currently, monoclonal antibody therapies are among the most effective treatments for COVID-19. The treatment injects a person’s body with COVID-19 antibodies that help the immune system neutralize virus cells and prevent them from multiplying.
