- Doctors use CAR-T cells to fight cancer.
- CAR-T works well in some blood cancers.
- CAR-T has had limited success in solid tumors.
- Problems include poor tumor penetration and side effects.
- Researchers made a new CAR-T system for control.
- The new cells need a small guide to attack.
- If the guide is gone, cells stop acting.
- The system can change which tumor the cells target.
- Doctors can stop the guide to pause therapy.
- This may make treatment safer for patients.
