Scientists at the University of Washington have engineered human plasma B cells modified to express long-lasting bispecific antibodies that could be used to treat leukemia without requiring continuous dosing.

“We are trying to engineer plasma cells to make as a stable source for biologic drugs. One thing that is really unique about plasma cells is that they can live for a really long time … up to 10 years or even 100 years depending on the type of plasma cell that that you make,” Richard James, senior author of the study, principal investigator at Seattle Children’s Research Institute, and associate professor at the University of Washington, told BioWorld.
