When cells become cancerous, the sugars on their surfaces undergo distinct changes that set them apart from healthy cells. Boons has synthesized a vaccine that, in mice, has successfully triggered a strong immune response to cancer cells. His group is currently testing and refining the vaccine, and hopes to start clinical trials in humans soon.

Lance Wells

Pancreatic cancer has the worst 5-year survival rate (1%) of any cancer, primarily due to a lack of early diagnostic tests. Wells is studying proteins and the sugars that adorn them in pancreatic ductal fluid from patients to find early diagnostic biomarkers. These biomarkers also have the potential to be targets for new therapeutic drugs.
