CAR-T and the C-word

Doug Olson was treated with engineered T cells (CAR-T) for incurable leukemia in 2010, well before CRISPR was born. Over a decade later, he still is cancer-free (see the paper in Nature), and the pioneer of the approach, Carl June, is reported to have said the C-word: cured. As immunotherapy and genome editing are crossing paths, hopefully, we expect further good news from the CAR-T frontier in the future.
