Researchers at Texas A&M University have created a caffeine-operated molecular switch, named CODS, utilizing artificial intelligence to control engineered cells in therapies. This innovation allows for the rapid separation of proteins in response to caffeine, enhancing the safety and controllability of gene and cell therapies.
- 01The caffeine-operated dissociation system (CODS) enables rapid protein separation in living cells, controlled by caffeine.
- 02The system can reduce gene activity and trigger programmed cell death, offering potential for safer cell therapies.
- 03CODS can serve as a safety switch for CAR T-cell therapies, allowing temporary reduction of immune cell activity.
- 04The AI-driven design process relied on high-performance computing to create and test synthetic protein binders.
- 05Future applications may include programmable medicines using familiar molecules for enhanced control over engineered therapies.

Researchers from the Texas A&M Health Institute of Biosciences and Technology have developed a novel molecular switch called CODS (caffeine-operated dissociation system) that utilizes artificial intelligence to control engineered cells in therapeutic applications. This system allows for the rapid separation of proteins in response to caffeine, which can help create safer and more controllable gene and cell therapies. The study, led by Yubin Zhou, MD, Ph.D., and his team, demonstrated CODS's ability to regulate gene activity, induce programmed cell death, and act as a safety switch for CAR T-cells, which are engineered to target cancer. By using AI-guided protein design and high-performance computing, the researchers were able to create a system that responds to low caffeine concentrations and can be reversed multiple times. While caffeine itself is not a treatment, it serves as a familiar signal for controlling engineered cells, paving the way for more programmable and responsive therapies in the future.
