"Ramsdell, a scientific advisor with Sonoma Biotherapeutics in San Francisco, shares the prize with Mary Brunkow of the Institute for Systems Biology in Seattle and Shimon Sakaguchi of Osaka University in Japan for their collective research on how immune cells known as regulatory T cells prevent the immune system from harming the body’s own tissues.
Their discoveries, the Nobel committee noted, have laid the foundation for a new field of research known as peripheral immune tolerance and have spurred the pursuit of regulatory T cell–centered therapeutics in areas like cancer, autoimmune disease and organ transplantation. There are currently more than 200 ongoing clinical trials based on their research."
