CAR-T cell therapy has demonstrated efficacy in hematopoietic tumors such as leukemia, myeloma, and non-Hodgkin's B-cell lymphoma in patients refractory to chemotherapy. However, in solid tumors, they are still limited by several barriers, including limited migration and invasion to tumor cells, the presence of an immunosuppressive tumor microenvironment, and adverse events associated with such therapies. In recent years, next-generation CAR immune cell technology has expanded and made progress in augmenting immune cells, activating endogenous immunity, and arming cells to resist suppression by the tumor microenvironment.
