A defining feature of these cancers is the loss of a protective gene called RB, which normally acts as a brake on cell growth. Without RB, cancer cells multiply rapidly and resist many targeted therapies.

This is the goal of Professor Ole Schmeltz Søgaard and an international team of researchers—to enable more patients' immune systems to keep the virus permanently in check without the need for daily medication. Their findings suggest that this requires two key components working in tandem: antibodies and T cells.
