flag Antibodies and T cells caused rejection of edited pig kidneys in a brain-dead human, but drugs reversed it, aiding progress toward solving organ shortages.

flag Scientists have identified the immune system's role in rejecting genetically edited pig kidneys transplanted into a brain-dead human, a breakthrough that could help address the severe shortage of human donor organs. flag In a study published in Nature, NYU Langone researchers monitored the kidney for 61 days, finding rejection was driven by antibodies and T cells, which were successfully reversed using FDA-approved drugs. flag Blood biomarkers detected rejection up to five days before tissue damage, enabling earlier treatment. flag With over 100,000 Americans awaiting kidney transplants and 12 dying daily, the findings bring pig-to-human transplants closer to reality, though challenges remain.
