The Nobel Assembly at the Karolinska Institute has decided to
award the 2018 physiology or medicine prize jointly to James P. Allison and
Tasuku Honjo "for their discovery of cancer therapy by inhibition of
negative immune regulation."
This year's laureates showed how different strategies for
inhibiting the brakes on the immune system can be used in the treatment of
cancer. Their discoveries are a landmark in the fight against cancer, the
committee said.
Edward Smith, member of the Nobel Committee, told Xinhua that
the significance of this year's award pointed to a "new fashion" in
cancer treatment. All previous treatments focused on tumor cells, but this
one was focused on the immune system.
Cancer kills millions of people every year and is one of
humanity's greatest health challenges. By stimulating the inherent ability of
our immune system to attack tumor cells this year's Nobel Laureates have
established an entirely new principle for cancer therapy, said a statement
released by The Nobel Assembly.
Allison studied a known protein that functions as a brake on the
immune system. He realized the potential of releasing the brake and thereby
unleashing our immune cells to attack tumors. He then developed this concept
into a brand new approach for treating patients.
In parallel, Honjo discovered a protein on immune cells and,
after careful exploration of its function, eventually revealed that it also
operates as a brake, but with a different mechanism of action. Therapies
based on his discovery proved to be strikingly effective in the fight against
cancer, according to the statement.
Allison and Honjo showed how different strategies for inhibiting
the brakes on the immune system can be used in the treatment of cancer. The
seminal discoveries by the two Laureates constitute a landmark in our fight
against cancer, the statement added.
Thomas Perlmann, secretary-general of the Nobel Committee and
the Nobel Assembly, told a press conference that Honjo "sounded
extremely pleased" at the news.
This year's prize is 9 million Swedish krona (about US$ 1
million).
