Canadian cell biologist Ralph Steinman (68), who was awarded the Nobel Prize for medicine on Monday for his pioneering work on the immune system, died of pancreatic cancer last week, his employer said.
“Steinman passed away on September 30,” Rockefeller University said in a statement. “He was diagnosed with pancreatic cancer four years ago, and his life was extended using a dendritic-cell based immunotherapy of his own design.”
Steinman shared the award with Bruce Beutler of the United States and Luxembourg-born Jules Hoffmann, who is a naturalised French citizen.

“But the news is bittersweet, as we also learned this morning from Ralphs family that he passed a few days ago after a long battle with cancer.
