How B cells fight the COVID-19 virus.

Inside the body of a person with COVID-19, the immune system’s B cells are engaged in a full-scale battle with the SARS-CoV-2 virus. But some B cells are better at this than others. Now, scientists from the Broad Institute of MIT and Harvard, Massachusetts General Hospital, California Institute of Technology, Brigham and Women’s Hospital, and other institutions have for the first time described key characteristics of B cells that are effective at neutralizing, or inactivating, the SARS-CoV-2 virus and related coronaviruses.

The team studied blood samples from 14 people who recovered from COVID-19, and revealed distinct patterns of gene expression in B cells that produce antibodies that bind tightly to and neutralize SARS-CoV-2. They also discovered a new antibody, BG10-19, which neutralizes the virus, variants of concern such as ones first identified in the UK and South Africa, and the coronavirus that caused the 2003 SARS outbreak.

The findings, published today in Cell, could help scientists better understand why some people don’t respond as well to existing COVID-19 vaccines or therapies, a first step toward improving vaccines and treatments.
