CAR-T Cells For Treating Systemic Lupus Erythematosus: A Promising Emerging Therapy.

Chimeric Antigen Receptor T-cell therapy (CAR-T), currently employed routinely for treating B-cell malignancies, has emerged as a groundbreaking approach in addressing severe autoimmune diseases, especially for systemic lupus erythematosus (SLE). The immunological rationale for targeting B lymphocytes in autoimmune diseases is well-established, demonstrating success in numerous autoantibody-mediated autoimmune conditions through targeted therapies over several years. However, this approach has often proven ineffective in the context of systemic lupus erythematosus. Recent data on CAR-T usage in lupus, revealed promising results including rapid and prolonged remission without treatment, highlighting the potential of CAR-T therapy in severe lupus cases. This article provides a comprehensive overview of CAR-T cells, tracing their evolution from hematological malignancies to their recent applications in autoimmune disorder, especially in lupus. Clinical trials within a regulated framework are now imperative to assess the procedural aspects in order to validate the considerable promise of CAR-T cell therapy in the field of autoimmune diseases. This includes evaluating safety and long-term efficacy and security of the procedure, the benefit-risk ratio in the field of autoimmunity, the availability and cost-related issues associated with this emerging cellular therapy procedure.
