Brief Summary

A Study of CD19/BCMA Chimeric Antigen Receptor T Cells Therapy for Patients With Refractory Immune Nephritis

Detailed Description

Immune nephritis is a chronic glomerular disease originating in the kidney caused by various etiologies.Clinically, secondary chronic kidney damage caused by systemic diseases such as diabetes, systemic lupus erythematosus and gout is named after its primary disease, such as diabetic nephropathy and lupus nephritis. Autoimmune diseases only show local pathological damage, but more often systemic lesions. If not diagnosed and treated in time or poorly controlled, a risk of disability or even death as the course of the disease progresses. Studies have shown that B cells can present their own antigens to autoimmune T cells to promote the release of inflammatory factors, or they can differentiate into plasma cells to release autoantibodies, and play an important role in the occurrence and progression of autoimmune diseases. In recent years, it has become a major research focus to deplete B cells in patients or inhibit B cell function. This research focuses on CAR-T cells killing B cells. Based on the current research progress, our center intends to conduct research on the safety and effectiveness of CD19/BCMA CAR-T cells in the treatment of refractory systemic lupus erythematosus.
