CAR T-cells: current limitations and future developments
Résumé
Chimeric antigen receptor (CAR) T-cells represent a great breakthrough in the treatment of hematologic malignancies. To date, two different CAR T-cells have been approved for the treatment of relapsed/refractory B-cell acute lymphoblastic leukemia and diffuse large B-cell lymphoma. Despite a remarkable efficacy, their use is limited by the occurrence of resistances and/or severe toxicities. A better understanding of these mechanisms and the progress in molecular intervention are paving the way for the development of new generations of CAR T-cells, with enhanced efficacy and/or reduced toxicity. Here, we review the mechanisms of resistance and toxicity, and the strategies which are envisioned to optimize CAR T-cell therapy.
