This research combines focused ultrasound and engineered genetic circuits to activate cancer immunotherapy directly within solid tumors. By locally triggering immune-stimulating cytokines such as IL-12, the approach aims to convert “cold” tumors into “hot” tumors while minimizing systemic toxicity, potentially expanding curative immunotherapy treatments to more cancer patients.

Pancreatic ductal adenocarcinoma resists immunotherapy by building an immune-suppressive tumor fortress. This research explores how specific bacteria found in long-term survivors may reshape the tumor microenvironment, enhance immune checkpoint therapy, and help immune cells overcome suppression to attack pancreatic cancer more effectively.
