Pancreatic cancer is notoriously hard to treat and often resists the most advanced immunotherapies.
Northwestern Medicine scientists have uncovered a novel explanation for that resistance: Pancreatic tumors use a sugar-based disguise to hide from the immune system.
The scientists also created an antibody therapy that blocks the sugar-mediated “don’t-attack” signal.
For the first time, the team identified how this sugar trick works and showed that blocking it with a monoclonal antibody reawakens immune cells to attack cancer cells in preclinical mouse models.
