Though it originates from the body's own cells, a tumor is as much of a hostile invader as any virus or bacterium. If the immune system is sufficiently sensitized, it can mount a counterattack just as it might fight an infection. For many patients, this response is insufficient, but researchers led by Jean-Pierre Abastado of the A*STAR Singapore Immunology Network have uncovered an immune mechanism that may help patients with hepatocellular carcinoma (HCC) keep their liver cancer at bay.
