and, when chemotherapy is used in combination with the immunotherapy, it dies.

According to Sela, the study sheds light on the synergy at work in the antibody-receptor therapy system. The results demonstrate that with the right combination of antibodies, receptor degradation is accelerated: it's more than three times as effective as a single antibody in inhibiting HER2 signaling.

"Understanding how HER receptor degradation works could enhance weak therapeutic efficacy, as well as provide ways to sensitize patients to overcome inherent or acquired resistance to cancer treatment," says Yarden.
