The Science of Celiac Disease
Summary
Professor Luke O’Neill explains celiac disease as a dual immune response to gluten and the body’s own transglutaminase enzyme, driven by specific HLA genetics. He details how this autoimmune overlap offers insights into other conditions like rheumatoid arthritis. The episode highlights new therapeutic advances, including gluten tolerance patches and a promising Phase 2 trial blocking IL-15 to protect the gut, offering hope for easier management of the disease.
