Researchers link a genetic risk variant to IL-10-blocking antibodies in a distinct subgroup of Crohn’s and ulcerative colitis patients.

The Discovery Applies to a Subgroup

IL-10 Normally Controls Inflammation

Autoantibodies Disable That Brake

The Antibodies Were Not Found in Healthy Controls

Both Main Forms of IBD Were Affected

A Genetic Variant Provides the Missing Link

Rare Childhood Cases Pointed the Way

A Blood Test Could Identify Patients

Treatment Could Target the Antibodies

Scientists have not discovered one universal cause of every case of inflammatory bowel disease. Instead, researchers from the University of Oxford, Newcastle University and Cambridge University Hospitals have identified a distinct autoimmune mechanism that appears to drive illness in a measurable subgroup of patients.

The study, published in the New England Journal of Medicine on June 10, 2026, analysed more than 4,900 people with Crohn’s disease or ulcerative colitis. It connects a long-known genetic risk factor to antibodies that disable one of the immune system’s most important controls on intestinal inflammation.
