Researchers affiliated with the University of Pennsylvania have found that the drug diABZI was highly effective at preventing severe COVID-19 symptoms in mice that were infected with multiple SARS-CoV-2 variants, as described in their paper published in Science Immunology on May 18. The researchers found that SARS-CoV-2 hides to avoid the activation of interferons, which are proteins that signal the presence of a virus, in the respiratory tract's epithelial cells. This results in a delayed immune response, which allows the virus to infect the respiratory tract. The researchers sought out to look into additional immune pathways. They looked at diABZI,...
