Three Scientists Win Nobel Prize for Immune System Breakthroughs
The 2023 Nobel Prize in Physiology or Medicine has been awarded to three scientists for groundbreaking work in understanding and harnessing the body's immune system. Mary Brunkow and Fred Ramsdell, along with Shimon Sakaguchi, received the prestigious honour for their discoveries related to peripheral immune tolerance and regulatory T cells, which control other immune cells and ensure the immune system does not attack the body's own cells.
The trio's work began in the early 2000s when Brunkow and Ramsdell discovered a mutation in the Foxp3 gene in mice. This gene plays a crucial role in the development and function of regulatory T cells. Later, scientists proved that mutations in the human Foxp3 gene cause IPEX syndrome, a severe autoimmune disorder.
Sakaguchi's pioneering work in the 1990s laid the foundation for this research. He discovered a new class of immune cells that protect from autoimmune diseases, further elucidating the role of regulatory T cells in immune tolerance. The discoveries of these scientists have paved the way for treatments of cancer, autoimmune diseases, and enhanced transplant effectiveness, with some treatments currently in clinical trials.
The 2023 Nobel Prize in Physiology or Medicine recognises the transformative impact of Brunkow, Ramsdell, and Sakaguchi's work on our understanding and treatment of immune-related disorders. Their discoveries have opened new avenues for medical research and patient care.
