James P. Allison of MD Anderson Cancer Center in Houston and Tasuku Honjo of Kyoto University in Japan have won the Nobel Prize in physiology or medicine for advances in harnessing the immune system to fight cancer.
All previous types of cancer therapy were directed at the tumor cell, but Allison’s and Honjo’s approach was to remove brakes that keep the immune system in check, unleashing it against tumor cells. These “checkpoint inhibitor” therapies have greatly increased survival of cancer patients and may produce even greater results when combined with traditional therapies.
The researchers will equally share the prize of 9 million kronor, equivalent to just over $1 million.
