During the covid-19 pandemic, antibodies played a front-and-center role. We used home tests to look for them, and we took vaccines so our bodies would make more.Less attention was paid to B cells, the immune-system cells that actually make antibodies, churning out as many as 10,000 a second—and which, after an infection, can persist for years inside your bone marrow.

Now a biotechnology company based in Seattle says the US Food and Drug Administration has agreed to let it move forward with the first study in humans of a new type of gene therapy, using genetically engineered B cells. The company, Immusoft, plans to harness B cells to treat a rare inherited disease called MPS-1. If it’s successful, it could overhaul how we treat similar conditions in the future.
