2025 Nobel Prize in Physiology or Medicine Awarded for Groundbreaking Immune System Research

The Nobel Prize in Physiology or Medicine for 2025 has been awarded to three distinguished scientists for their pivotal research on how the immune system maintains balance and avoids attacking the body’s own tissues. Mary E. Brunkow, Fred Ramsdell, and Shimon Sakaguchi have been recognized for their significant discoveries concerning peripheral immune tolerance. This prestigious announcement was made on Monday by the Nobel Assembly at the Karolinska Institute in Stockholm, Sweden. The laureates will share a prize amounting to 11 million Swedish kronor, equivalent to approximately 871,400 USD. This marks the 116th Nobel Prize awarded in the field of physiology or medicine, with 13 of those prizes previously bestowed upon women. In an exciting turn, last year's award was given to Victor Ambros and Gary Ruvkun for their groundbreaking work on microRNA—tiny RNA molecules that play a crucial role in regulating protein production within cells. As world attention turns to this year's Nobel winners, further details and insights into their groundbreaking work and its implications for medical science will be shared soon, shedding light on the future of immune system research and its potential impact on health and disease treatment.
