A study led by the GEM Project’s Dr. Ken Croitoru and Dr. Sun-Ho Lee has found that a blood test can predict Crohn’s disease years before symptoms appear, opening the doors to early diagnosis and potentially prevention. The test measures a person’s immune response to flagellin, a protein found on gut bacteria. The GEM team found that this response is elevated in individuals long before they develop Crohn’s Disease. These findings raise the potential for designing a flagellin-directed vaccine in selected high-risk individuals for prevention of disease. Read the news release from Sinai Health here.
