Scientists develop first-of-its-kind antibody to block Epstein Barr virus

Fred Hutch Cancer Center scientists reached a crucial milestone in blocking Epstein Barr virus (EBV), a pathogen estimated to infect 95% of the global population that is linked to multiple types of cancer, neurodegenerative diseases and other chronic health conditions. Using mice with human antibody genes, the research team developed new genetically human monoclonal antibodies that prevent two key antigens on the surface of the virus from binding to and entering human immune cells.

Published in Cell Reports Medicine, the study highlights one of the newly identified monoclonal antibodies that successfully blocked infection in mice with human immune systems when they were challenged with EBV.

“Finding human antibodies that block Epstein Barr virus from infecting our immune cells has been particularly challenging because, unlike other viruses, EBV finds a way to bind to nearly every one of our B cells,” explained Andrew McGuire, Ph.D., a biochemist and cellular biologist in the Vaccine and Infectious Disease Division at Fred Hutch. “We decided to use new technologies to try to fill this knowledge gap and we ended up taking a critical step toward blocking one of the world’s most common viruses.”
