Nobel Prize for Immune Tolerance

Mary E. Brunkow, Fred Ramsdell, and Shimon Sakaguchi have been awarded the Nobel Peace Prize in Physiology or Medicine for their groundbreaking discoveries concerning peripheral immune tolerance. Shimon Sakaguchi initially discovered regulatory T cells (T-regs) in 1995. Later, in 2001, Mary E. Brunkow and Fred Ramsdell identified a mutation in the Foxp3 gene, which is linked to autoimmune diseases. In 2003, Shimon Sakaguchi connected these findings, demonstrating that the Foxp3 gene controls the development of T-regs, which are crucial for preventing the immune system from attacking the body's own tissues. These discoveries have launched the field of peripheral tolerance and are expected to lead to new medical treatments for cancer, autoimmune diseases, and more successful transplantations, with several treatments already in clinical trials. The Nobel Peace Prize, including 11 million Swedish kronor, was announced by the Nobel Committee at the Karolinska Institute in Stockholm.
