Editorial: CAR T-cells: novel therapeutic approaches in the new era of cancer immunotherapy

subject

description

Immunotherapy has emerged as one of the most effective treatments capable of overcoming tumor resistance mechanisms due to its ability to modulate the patient’s immune response against cancer. Personalized anti-tumor therapy based on T cells engineered to express a cancer-specific chimeric antigen receptor (CAR) acts directly on the immune system of patients. Specifically, this therapy enhances the recognition of cancer cells by T lymphocytes, thus promoting their elimination. In this Research Topic several aspects of CAR T-cell therapy, with particular emphasis on novel findings aimed at ameliorating the effectiveness of CAR T-cell-based immunotherapy and reducing side effects, are described (Figure 1).
