Other tech: Revving up the immune system in mice can kill cancer cells

White blood cells from a unique breed of cancer-resistant mice have cured advanced cancers in normal mice, researchers report. When injected the immune cells sought out and killed existing tumours and also protected the mice against lethal doses of new, highly aggressive cancers.

The “resistant-cell therapy” appears to work without toxic side effects, and the researchers hope that a greater understanding of the mechanism may enable the technique to be used in humans in the future.
