Dual Target CAR-T Cell Treatment for Refractory Systemic Lupus Erythematosus (SLE) Patients

Systemic lupus erythematosus (SLE) is a kind of autoimmune diseases mediated by autoantibody-forming immune complexes, which involving multiple systems and organs. Autoreactive B cells can self-activate and differentiate into plasma cells releasing large amounts of autoantibodies, while they can also present their own antigens to autoimmune T cells, thus activating T cells and promoting the release of inflammatory factors. Traditional SLE treatment aims at long-term remission, while, CD19- BCMA CAR-T cells can theoretically completely deplete abnormal antibody-producing B cells, allowing immune rebuilding and restoring the patient's normal immune function, achieving drug-free survival, which fully reflects the application prospects of CAR-T therapy in SLE.
