‘Algae’ Allies: Protein from Cyanobacteria Blocks SARS-CoV-2 Infection in Lab Studies
Early in the COVID-19 pandemic, before vaccines were available and while SARS-CoV-2 was wreaking havoc worldwide, Barry O’Keefe, Ph.D., and longtime collaborators in Brazil and Spain pooled their knowledge and resources to study cyanovirin-N (CV-N), a protein from cyanobacteria, photosynthetic bacteria commonly known as blue-green algae. O’Keefe had a hunch it could be developed to fight the spread of SARS-CoV-2.
