Meet Shimon Sakaguchi, Winner Nobel 2025 in Medicine

Dr. Shimon Sakaguchi, Mary E. Brunkow, and Fred Ramsdell were awarded the Nobel Prize in Physiology or Medicine for discovering peripheral immune tolerance. Their work identified regulatory T-cells (Tregs) and the FOXP3 gene, solving the paradox of how the immune system protects the body without attacking its own healthy tissues.
