Tiny clusters in the lymph nodes, germinal centers refine antibodies through mutation and expansion until they produce high-affinity B cells adapted to keep different pathogens in check. But...

Clinical trial: Off-the-shelf immunotherapy shows promise for B-cell lymphoma
by Julia Evangelou Strait, Washington University in St. Louis A phase 1 clinical trial co-led by researchers at WashU Medicine found that a new type of cell-based immunotherapy was safe for patients with several types of B-cell lymphoma, a type of blood cancer. Larger studies are needed to assess efficacy, but the approach shows promise. Pictured...
Targeting type of B cell could reduce lupus disease, study suggests
by University of Pittsburgh Credit: Pixabay/CC0 Public Domain A group of University of Pittsburgh researchers has given new meaning to “knowing your ABCs.” In a new study, published in the Journal of Experimental Medicine, the team showed that a type of immune cell called age-associated B cells, or ABCs, are important drivers of lupus and that targeting these...
When the body’s B cell training grounds stay open after hours
by Rockefeller University Graphical abstract. Credit: Cell (2022). DOI: 10.1016/j.cell.2022.11.031 If B cells are the munitions factories of the immune system, manufacturing antibodies to neutralize harmful pathogens, then the tiny biological structures known as germinal centers are its weapons-development facilities. Formed in response to infection and vaccination, these microscopic training grounds allow B cells to perfect the...
Researchers use custom molecule to halt growth of multiple myeloma and diffuse large B cell lymphoma in mice
