Congratulations to new Nobel Laureate and AAI Distinguished Fellow Shimon Sakaguchi, co-winner of the 2025 Nobel Prize in Physiology or Medicine for his foundational discoveries on regulatory T cells and peripheral immune tolerance! Published in The JI in 1995: ow.ly/LGk150X7984.
Immunologic self-tolerance maintained by activated T cells expressing IL-2 receptor α-chains (CD25). Breakdown of a single mechanism of self-tolerance causes various autoimmune diseases
Abstract. Approximately 10% of peripheral CD4+ cells and less than 1% of CD8+ cells in normal unimmunized adult mice express the IL-2 receptor α-chain (CD2
