Story summary

Researchers from Arc Institute, Gladstone Institutes, and the University of California, San Francisco published an epigenetic editing platform for modifying human T cells in Nature Biotechnology October 21, 2025.
The platform uses CRISPRoff and CRISPRon to silence or activate genes without DNA damage.
Enhanced CAR-T cells showed improved tumor-killing capacity in lab and mouse models, suggesting the approach could advance treatments for cancer and autoimmune disorders, with clinical trials underway.
