Researchers develop method to program immune cells inside the body to fight cancer

Scientists at Karolinska Institutet and the University of California, San Francisco have developed a new method that allows CAR-T cells to be produced directly in the body to target and kill tumors. In experiments on mice, the technique has shown effectiveness against multiple cancer types, eliminating the need to extract and process immune cells in a lab. This approach could make CAR-T cell therapy, currently an advanced and costly treatment for blood cancer, more accessible and faster than existing methods that take weeks.
