Nobel-winning research releases immune system brakes to fight cancer

6:17 min

This year's Nobel Prize in Physiology or Medicine salutes a new type of cancer therapy, which doesn't target cancer cells themselves but releases the brakes on the immune system so it can fight the cancer.

America's James Allison and Japan's Tasuku Honjo jointly won the prize on Monday for their groundbreaking discoveries about how to use the body's immune system to fight cancer.

Radio Sweden interviews Klas Kärre, professor of molecular immunology at Karolinska Institutet and a member of this year's Nobel Committee, to find out how it works.
