Co-author of the publication, Dr. Barton Haynes believes that these antibodies canBe therapeutic
Researchers tested the blood of people whosuffered from the original SARS-CoV-1 virus (SARS, an outbreak of which occurred 20 years ago), and SARS-CoV-2 (COVID-19). Scientists have isolated 1,700 antibodies produced by the human immune system to block the pathogen from infecting cells. 50 antibodies are highly effective against various types of coronaviruses. They target binding sites (sites in a molecule that are able to enter into stable interaction with other molecules or cellular structures - "Hi-tech") viruses that do not change during their mutation.
One of the types of antibodies was found to be the most powerful. It is capable of interacting with many types of animal coronavirus in addition to the two pathogens that infect humans.
A test in mice has shown that this type of antibody can effectively block infections and prevent infection, or minimize its consequences.
PhD, Department of Epidemiology, Gillings SchoolUniversity of North Carolina's David Martinez believes the antibodies can be used to treat the current COVID-19 pandemic, as well as to prevent the outbreak of any other SARS virus that is associated with SARS. He suggested that this type of antibody could be used against potentially possible SARS-CoV-3 or SARS-CoV-4 epidemics.
