Researchers at EPFL have created artificial molecules that can help the immune system to recognize and attack cancer tumors. Immunotherapies are breakthrough treatments that stimulate the patient’s immune cells to attack the tumor through the recognition of tumor antigens. They can be very effective, but currently can only cure a minority of patients with solid tumors. Researchers and physicians are now looking into ways of increasing the precision and strength of the immune attack on the tumor.

One approach is the “dendritic cell vaccine...
