Fourth-gen CAR T Cells Targeting BCMA/CD19 for Refractory Systemic Lupus Erythematosus (SLE)

Systemic lupus erythematosus (SLE) is a type of autoimmune disorder characterized by the creation of autoantibody-generating immune complexes, affecting various systems and organs. In SLE, autoreactive B cells can self-activate and morph into plasma cells that produce a high volume of autoantibodies. These cells can also expose their own antigens to autoimmune T cells, thereby stimulating T cells and leading to the release of inflammatory substances. Conventional treatment for SLE focuses on achieving prolonged remission. In contrast, CD19-BCMA CAR-T cells offer a potential solution by eradicating the abnormal B cells responsible for antibody production. This allows for the rebuilding of the immune system and the restoration of normal immune function in patients, potentially leading to a life free from medication. This highlights the promising potential of CAR-T therapy in treating SLE.
