Brunkow<\/strong>, <strong data-start=\"228\" data-end=\"245\">Fred Ramsdell<\/strong>, and <strong data-start=\"251\" data-end=\"271\">Shimon Sakaguchi<\/strong> \u2014 for their revolutionary research that revealed how the immune system protects the body from self-destruction while defending against countless invading microbes. The trio was honored in Stockholm, Sweden, for their \u201c<em>fundamental discoveries relating to peripheral immune tolerance<\/em>,\u201d the <a href=\"https:\/\/newsraise.com\/index.php\/2025\/06\/21\/pakistan-nominates-trump-for-nobel-prize-applaud-his-leadership-during-india-pak-conflict\/\">Nobel Committee announced<\/a> on October 6.<\/p>\n<h3 data-start=\"604\" data-end=\"643\"><strong>Discovery That Changed Immunology<\/strong><\/h3>\n<p data-start=\"645\" data-end=\"1071\">The laureates\u2019 work centers on the discovery of regulatory T cells (Tregs) \u2014 specialized immune cells that act as the body\u2019s security guards, ensuring that the immune system does not mistakenly attack its own tissues.<\/p>\n<ul>\n<li data-start=\"645\" data-end=\"1071\">This mechanism is crucial in preventing autoimmune diseases, where the immune system targets healthy cells, leading to conditions such as lupus, rheumatoid arthritis, and multiple sclerosis.<\/li>\n<li data-start=\"645\" data-end=\"1071\">Their research has also paved the way for new therapeutic strategies that could lead to effective treatments for autoimmune disorders and reduced complications after organ and stem cell transplants.<\/li>\n<\/ul>\n<h3 data-start=\"1544\" data-end=\"1589\"><strong>How the Immune System Protects the Body<\/strong><\/h3>\n<p data-start=\"1591\" data-end=\"2011\">The immune system is an &#8216;evolutionary masterpiece&#8217;\u00a0as described by the committee. It protects the body by distinguishing harmful pathogens from normal cells and then attacking the invaders. However, some pathogens cleverly camouflage themselves by mimicking human cells, confusing the immune system and causing it to launch a misguided attack on the body\u2019s own tissues \u2014 a hallmark of autoimmune diseases.<\/p>\n<h3 data-start=\"2013\" data-end=\"2046\"><strong>Sakaguchi\u2019s Pioneering Work<\/strong><\/h3>\n<p data-start=\"2048\" data-end=\"2474\">Japanese immunologist Shimon Sakaguchi, now based at Osaka University, made a landmark discovery in 1995 while studying mice. His experiments revealed that the immune system, relying on a set of regulatory T cells maintain balance and prevent self-destruction. This insight provided a missing link in understanding why the immune system doesn\u2019t attack the body more often.<\/p>\n<h3 data-start=\"2476\" data-end=\"2525\"><strong>Brunkow and Ramsdell\u2019s Genetic Breakthrough<\/strong><\/h3>\n<p data-start=\"2527\" data-end=\"2913\">Building on Sakaguchi\u2019s foundation, Mary E. Brunkow and Fred Ramsdell, both American researchers, made their breakthrough in the early 2000s. They discovered a mutation in a gene they named Foxp3, which showed that this gene is essential for the development and function of regulatory T cells.<\/p>\n<p data-start=\"2915\" data-end=\"3250\">Further studies revealed that mutations in the human FOXP3 gene cause IPEX syndrome, a rare but fatal autoimmune disorder in infants. In 2003, Sakaguchi confirmed that the Foxp3 gene governs the creation of regulatory T cells, linking both discoveries and cementing their collective contribution to modern immunology.<\/p>\n<h3 data-start=\"3252\" data-end=\"3286\"><strong>Transforming Modern Medicine<\/strong><\/h3>\n<p data-start=\"3288\" data-end=\"3725\">The Nobel Committee emphasized that these findings have far-reaching implications for medicine. Their discovery continues to influence research into immune regulation, tolerance, and immunotherapy across the world.\u00a0The <a href=\"https:\/\/newsraise.com\/index.php\/2019\/10\/16\/humans-would-never-migrate-to-other-planets-claims-nobel-prize-winner-michel-mayor\/\">2025 Nobel Prize in Physiology or Medicine<\/a> includes a cash award of whopping <strong><em>11 million Swedish kronor (approximately $1 million),<\/em><\/strong> shared equally amongst the three laureates.<\/p>\n<p data-start=\"3950\" data-end=\"4268\">This year\u2019s <a href=\"https:\/\/newsraise.com\/index.php\/2025\/07\/08\/netanyahu-and-trump-discuss-palestine-issue-latter-gets-nominated-for-nobel-prize\/\">Nobel Prize underscores the power of curiosity-driven science<\/a> and collaboration across decades and continents.
