CAR-T Cell therapy in T-cell malignancies: limitations and solutions

Abstract

CD19-targeted chimeric antigen receptor (CAR)-T cell therapy has shown high potential for treating B-cell hematological malignancies and has been approved by the US FDA. However, CAR-T cell therapy for T-cell hematologic malignancies poses feasibility challenges, including the difficulty of obtaining sufficient healthy cells from patients, CAR-T cell fratricide, and the risk of immunodeficiency. In this review, we discuss bottlenecks and possible solutions in CAR-T cell therapy for T-cell acute lymphoblastic leukemias, as well as future directions in this field.
