Introduction to the Nobel Laureates and Their Discoveries
The 2025 Nobel Prize in Medicine has been awarded to scientists Mary E. Brunkow, Fred Ramsdell, and Shimon Sakaguchi for their groundbreaking discoveries on peripheral immune tolerance. This crucial finding explains how our body prevents self-destruction by regulating its powerful immune system, which could otherwise attack our own organs. Dr. José Luis Maravillas Montero, an immunologist at the Institute of Biotechnology at UNAM and a member of the Mexican Immunology Society board, elaborated on this topic for El Economista.
Understanding Peripheral Immune Tolerance
Peripheral immune tolerance refers to the mechanism that prevents the immune system from causing harm to our own body. The laureates identified regulatory T cells (Tregs) as the “security guards” of the immune system, which maintain balance and prevent autoimmune diseases. These cells ensure that the immune response is appropriately targeted against foreign invaders while avoiding attacks on our own tissues.
Relevance of the Nobel-Winning Discoveries
The significance of these discoveries lies in their potential to treat autoimmune diseases, such as rheumatoid arthritis, multiple sclerosis, and type 1 diabetes. By understanding how Tregs function, scientists can develop targeted therapies to enhance their activity and restore immune system balance in patients suffering from these conditions.
Nobel Prize Background and Upcoming Announcements
Since 1901, the Nobel Prizes and the Bank of Sweden’s Prize in Economic Sciences in Memory of Alfred Nobel have been awarded 628 times to 1015 individuals and organizations. With some recipients receiving the prize multiple times, this totals 979 people and 28 organizations.
The prize amount is 11 million Swedish kronor (approximately $1.2 million), divided equally among the laureates.
