Researchers are exploring ways to enhance CAR-T cell therapy for solid tumors, including remodeling the tumor microenvironment and engineering CAR-T cells to better target and infiltrate tumors. Various strategies are being investigated, such as blocking key proteins and modifying cellular metabolism, to improve the effectiveness of CAR-T cell therapy in solid tumors. The approaches being studied have potential applications for treating different types of cancer, including prostate, pancreatic, and other solid tumors.
