Harnessing tumor acidity: innovative lactic acid-responsive promoter enables precision control of CAR-T cell activity in solid tumors

Journal for ImmunoTherapy of Cancer | |

Background <p>The acidic tumor microenvironment (TME) in solid tumors, driven by abnormal metabolism and lactic acid accumulation, suppresses chimeric antigen receptor-T (CAR-T) cell efficacy while posing safety risks from on-target, off-tumor toxicity (OTOT). This study aims to develop a novel CAR-T technology that leverages lactic acid as a tumor-specific trigger to achieve precise control of CAR activity. The objective is…
