Breakthrough Gene Delivery System Targets Brain Cells with Laser Precision

Researchers from Andreas Pfenning's lab in the Ray & Stephanie Lane Computational Biology Department including current students and graduates of the Computational Biology PhD Program and Bill Stauffer's lab at the University of Pittsburgh have developed a revolutionary gene therapy system that can precisely target specific brain cell types—like having molecular switches that turn on genes in exactly the right cells.

This NIH-recognized breakthrough combines machine learning with viral delivery systems to create cellular "on/off switches" that activate treatments exactly where they're needed. Using rhesus monkey brain data, the team trained AI models to identify DNA sequences that act as precise molecular switches for specific cell types.

The game-changing potential? Instead of broad treatments that affect the entire brain, doctors could someday deliver pinpoint therapies for epilepsy, Parkinson's disease, ALS, and spinal cord injuries—flipping the therapeutic switch in damaged circuits while leaving healthy brain tissue untouched.

"This is like going from using a sledgehammer to using a surgeon's scalpel," the team explains. The technology opens doors to therapies that control neural activity with unprecedented precision, bringing us closer to conquering devastating neurological diseases at the molecular level.
