  "textContent": "Scientists have developed a way to turn the body's own immune cells into cancer-fighting agents—without removing them from the body—by using red blood cells to deliver genetic instructions. Current CAR (chimeric antigen receptor) therapies typically involve collecting a patient's T cells, genetically modifying them in the laboratory, and then reinfusing them in a process that can take weeks. The new strategy aims to bypass that step.",
