STOCKHOLM (Reuters) - A scientist who won the Nobel prize for medicine on Monday for work on fighting cancer died of the disease himself just three days before he could be told of his award, and after using his own discoveries to extend his life.
Canadian-born
Ralph Steinman, 68, had been treating himself with a groundbreaking therapy based on his own research into the body's immune system but died on Friday after a four-year battle with pancreatic cancer. His colleagues at Rockefeller University in New York called it a "bittersweet" honor.
The Nobel Committee at Sweden's Karolinska Institute, which does not make posthumous awards, said it was aware of Steinman's death; but it appeared that it had not known before making its announcement. It is likely that Steinman died without being aware he had won science's ultimate accolade, along with American Bruce Beutler and Jules Hoffmann of France.
Swedish officials on the Nobel Committee were rushing to try to clarify what secretary general Goran Hansson, called a "unique situation, because he died hours before the decision was made." Hansson told Swedish news agency TT the panel would review what to do with the prize money, due to rules against posthumous awards. But it would not name a substitute winner.
"The Nobel Foundation has recognized Ralph Steinman for his seminal discoveries concerning the body's immune responses," said Rockerfeller University president Marc Tessier-Lavigne.
"But the news is bittersweet, as we also learned this morning from Ralph's family that he passed a few days ago after a long battle with cancer," he added.
The institution said in a statement: "Steinman passed away on September 30. He was 68. He was diagnosed with pancreatic cancer four years ago, and his life was extended using a dendritic-cell based immunotherapy of his own design."
Alexis Steinman, indicating that her father had not known on his deathbed of the impending decision in Stockholm, said: "We are all so touched that our father's many years of hard work are being recognized with a Nobel Prize. He devoted his life to his work and his family and he would be truly honored."
Beutler and Hoffmann, who studied the first stages of the body's immune responses to attack in the 1990s, shared the $1.5 million award with Steinman, originally from Montreal, whose discovery of dendritic cells in the 1970s is key to understanding the body's next line of defense against disease.
"This year's Nobel laureates have revolutionized our understanding of the immune system by discovering key principles for its activation," the award panel at Sweden's Karolinska Institute said in a statement in Stockholm.
Lars Klareskog, who chairs the prize-giving panel, told Reuters before the news of Steinman's death: "I am very excited about what these discoveries mean. I think that we will have new, better vaccines against microbes and that is very much needed now with the increased resistance against antibiotics."
Beutler, 53, is based at the Scripps Research Institute in La Jolla, California. Luxembourg-born Hoffmann, 70, conducted much of his work in Strasbourg. They were supposed to share half the 10 million Swedish crowns ($1.46 million) of prize-money. The rest should have gone to Steinman, though the unusual circumstances leave its fate now in some doubt.
Beutler told Reuters he had learned of his prize by e-mail and had to search online to make sure it was true: "I finally found it on Google News. My name was all over the place."
Of his work, he said, it "might lead to new treatments for inflammatory and auto-immune disease and possibly new treatments for other kinds of diseases as well."
The work of all three scientists has been pivotal to the development of improved types of vaccines against infectious diseases and novel approaches to fighting cancer. The research has helped lay the foundations for a new wave of "therapeutic vaccines" that stimulate the immune system to attack tumors.
Better understanding of the complexities of the immune system has also given clues for treating inflammatory diseases, such as rheumatoid arthritis, where the components of the self-defense system end up attacking the body's own tissues.
Beutler and Hoffmann discovered in the 1990s that receptor proteins act as a first line of defense, innate immunity, by recognizing bacteria and other microorganisms. Steinman's work, explained how, if required, dendritic cells in the next phase, adaptive immunity, kill off infections that break through.
Understanding dendritic cells led to the launch of the first therapeutic cancer vaccine last year, Dendreon's Provenge, which treats men with advanced prostate cancer.
"We live in a dangerous world. Pathogenic microorganisms threaten us continuously," the Nobel panel said, describing the work over the decades in understanding our defenses.
"The first line of defense, innate immunity, can destroy invading microorganisms and trigger inflammation ... If microorganisms break through this defense line, adaptive immunity is called into action ... It produces antibodies and killer cells that destroy infected cells ... These two defense lines ... provide good protection against infections, but they also pose a risk ...: inflammatory disease may follow."
Medicine, or physiology, is usually the first of the Nobel prizes awarded each year. Prizes for achievements in science, literature and peace were first awarded in 1901 in accordance with the will of dynamite inventor and businessman Alfred Nobel.
The award citation noted that the world's scientists had long been searching for the "gatekeepers" of immune response.
Hoffmann's pioneering research was conducted on fruit flies, highlighting how key elements of modern human biology have been conserved through evolution.
The immune system exists primarily to protect against infections but it can also protect against some cancers by targeting rogue cells before they proliferate.
Sometimes, however, the immune system goes into overdrive and attacks healthy tissue, leading to autoimmune inflammatory diseases, such as type 1 diabetes and multiple sclerosis, as well as rheumatoid arthritis. The effect is often compared to "friendly fire," when troops hit their own comrades in combat.

(Reuters) - The Nobel Foundation said
on Monday a decision to award the 2011 Nobel Prize for medicine or
physiology to Canadian scientist Ralph Steinman would remain unchanged
despite his death.
Steinman was awarded the prize together with Bruce Beutler and Jules Hoffmann for increasing understanding of the immune system.
Rules
set up in 1974 prevent the Nobel Committee from awarding the prizes
posthumously, unless death has occurred after the announcement of the
Nobel Prize.
Steinman died on September 30 and the committee announced the prize without knowing of his death.
"The
events that have occurred are unique and, to the best of our knowledge,
are unprecedented in the history of the Nobel Prize," the foundation
said in a statement.
"According to
the statutes of the Nobel Foundation, work produced by a person since
deceased shall not be given an award. However, the statutes specify that
if a person has been awarded a prize and has died before receiving it,
the prize may be presented."
