CRISPR CAR-T cells can Revolutionize Cancer Treatment

Cancer is the second leading cause of death in the United States, taking half a million lives each year. CAR T technology has successfully harnessed the human immune system to produce awe-inspiring cancer remission rates. CRISPR-mediated genome engineering has enabled new developments in CAR T cells to bypass logistical, technical, and immunological roadblocks, making the
