By repositioning a small fragment of an HPV protein on a DNA-based nanovaccine, the team dramatically strengthened the immune system’s attack on HPV-driven tumors. One sp ecific design slowed tumor growth, extended survival in animal models, and unleashed far more cancer-killing T cells than other versions made with the exact same components. ...read more read less
