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.
At the 30th Annual Congress of the European Society for Gene and Cell Therapy in Brussels this week, researchers presented both preclinical and clinical strategies for applying gene therapy to a functional HIV cure. At a Wednesday session on Infectious Diseases & Vaccines, Alessio Nahmad, of Tabby Therapeutics Ltd., described using B cells edited to express broadly neutralizing antibodies (bnAbs) 3BNC117 to deliver high titers of antibodies in mice.

B cells that expressed a constellation of checkpoint inhibitors could be spurred into antitumor activity by deleting or blocking the checkpoint molecule T-cell immunoglobulin and mucin domain 1 (TIM-1). The findings, which were published online in Nature on June 21, 2023, suggest ways to bring B cells into the antitumor fight. More broadly, Lloyd Bod told BioWorld, his laboratory aims to “break the dogma that B cells only produce antibodies.”
Targeting the epigenetic histone modifier BMI-1 in B cells restored effective humoral immune responses to control chronic viral infection in mice, according to new multicenter Australian study led by immunologists at Monash University in Melbourne, Victoria.
Immune system B cells secrete the neurotransmitter gamma amino-butyric acid (GABA), which promotes generation of anti-inflammatory macrophages and blunts the cytotoxic T cell-based response to tumors in mice.

The axolotl, which can regenerate many of its body parts, was the inspiration for Walking Fish Therapeutics Inc., which just closed on a $50 million series A financing to advance its B-cell therapies for oncology, rare disease, regenerative medicine, autoimmune disease and recombinant antibody production.
A Chinese study has shown that the recently discovered transcription factor Bach2, which is important in B-cell development and progression of inflammatory disease, also regulates gastrointestinal regeneration by facilitating DNA repair after ionizing radiation exposure.
