The paper explores the development and clinical application of chimeric antigen receptor (CAR)-engineered natural killer (NK) cells as a transformative immunotherapy for cancer. While CAR-T cell therapy has succeeded in treating blood cancers, it faces hurdles in solid tumors due to high toxicity and complex manufacturing requirements. In contrast, CAR-NK cells offer a safer, more accessible "off-...
