CD19 CAR Engineered T Regulatory Cells Promote Durable Immune Tolerance in Experimental Systemic Lupus Erythematosus

Travis Drow, Matteo Doglio, Annaiz Grimm…·David J. Rawlings

This study shows that CD19 CAR-engineered regulatory T cells reduce B cell numbers, inflammation, and autoantibodies in lupus models, promoting long-term immune tolerance.

Antibody-dependent priming of spontaneous germinal centers by autoreactive B cells

Danny Kim, Kristy Chiang, Andrea D. Largent…·Shaun W. Jackson

This study shows autoreactive B cells can initiate spontaneous germinal centers and autoimmunity through antibody-dependent mechanisms, independent of T cell interactions or antigen presentation.
