The drugs work by blocking a protein, PD-1 — which helps keep immune responses in check — and stimulating the immune system to attack tumors. The team studied the immune response to CRISPR and designed a new technology that they published in 2021 — a way of removing immune-triggering molecules from CRISPR-edited cells.
