CAR-T cell therapy: A breakthrough in traditional cancer treatment strategies (Review)

Abstract

Chimeric antigen receptor (CAR)-T cell therapy is an innovative approach to immune cell therapy that works by modifying the T cells of a patient to express the CAR protein on their surface, and thus induce their recognition and destruction of cancer cells. CAR-T cell therapy has shown some success in treating hematological tumors, but it still faces a number of challenges in the treatment of solid tumors, such as antigen selection, tolerability and safety. In response to these issues, studies continue to improve the design of CAR-T cells in pursuit of improved therapeutic efficacy and safety. In the future, CAR-T cell therapy is expected to become an important cancer treatment, and may provide new ideas and strategies for individualized immunotherapy. The present review provides a comprehensive overview of the principles, clinical applications, therapeutic efficacy and challenges of CAR-T cell therapy.
