scientists Mary Brunkow, Fred Ramsdell and Shimon Sakaguchi from Japan won the 2025 Nobel Prize in Physiology or Medicine on Monday for their discoveries in controlling the immune system, creating openings for possible new autoimmune disease and cancer treatments.
This year's prize "relates to how we keep our immune system under control so we can fight all imaginable microbes and still avoid autoimmune disease," said Marie Wahren-Herlenius, a rheumatology professor at the Karolinska Institute.
Sakaguchi told reporters outside his university laboratory that "I feel it is a tremendous honour," Kyodo news agency reported.
The winners for medicine are selected by the Nobel Assembly of Sweden's Karolinska Institute medical university and receive a prize sum of 11 million Swedish crowns ($1.2 million), as well as a gold medal presented by Sweden's king.
