Scientists design protein that prods cancer-fighting T-cells

Scientists have created a new protein that mimics a key immune regulatory protein, interleukin 2 (IL-2). IL-2 is a potent anticancer drug, but with toxic side effects. The researchers report using computer programs to design a protein that they have shown in animal models to have the same ability to stimulate cancer-fighting T-cells as IL-2, but without triggering harmful side effects.
