Two share 2018 Nobel Prize in medicine for their cancer work

Two immunologists, James Allison of the United States and Japan's Tasuku Honjo, won the 2018 Nobel Prize in medicine for research that has revolutionized the treatment of cancer, the jury announced on Monday.

They were honored "for their discovery of cancer therapy by inhibition of negative immune regulation", the Nobel Assembly said.

Immune checkpoint inhibitor therapy targets proteins made by some immune system cells, as well as some cancer cells.
