Scientists reprogram immune cells inside the body to fight cancer

Scientists at UC San Francisco have developed a way to create cancer-fighting CAR-T cells directly inside the body, potentially avoiding the slow and extremely expensive process of removing, engineering, and reinfusing a patient’s immune cells. Using a two-particle delivery system, the researchers sent CRISPR gene-editing tools and new cancer-targeting DNA specifically into T cells, where the DNA was inserted at a precise location in the genome.
