CAR T cells in autoimmune disease: On the road to remission

Several recent reports have demonstrated that B cell-targeting chimeric antigen receptor (CAR) T cells offer a viable treatment option for patients with autoantibody-mediated autoimmune diseases. To present additional data on this therapy and discuss strategies for more efficient clinical translation, leading experts in CAR T cell therapy for autoimmunity from various countries, including China, Germany, and the United States, convened at the "1st International Autoimmune CAR T Innovators Summit" in Grassau, Germany, from May 10-12, 2024. The summit showcased additional insights of CAR T cell therapy in diverse autoimmune diseases and provided platforms for discussions on key questions through workshops and roundtables. Here, we summarize the recent findings and key developments reported at the summit.
