    Protein Zonulin Linked to Celiac Disease

    Reviewed and edited by a celiac disease expert.

    Celiac.com 05/14/2000 - Scientists from the University of Maryland have discovered that people with the autoimmune disorder celiac disease have higher levels of the protein zonulin in their bodies. This discovery may ultimately lead to more insight into the causes of other autoimmune diseases, including diabetes, multiple sclerosis and rheumatoid arthritis. In people with celiac disease who eat gluten, which is found in wheat, rye and barley, an autoimmune reaction is set off that creates antibodies that end up attacking their intestines. This causes symptoms like diarrhea and abdominal pain, and may lead to long-term damage and a large host of other problems. Researchers at the University of Maryland have finally found the cause of this curious reaction: a protein in the body called zonulin.

    Zonulin is a human protein that acts like a traffic conductor for the bodys tissues by opening spaces between cells, and allowing certain proteins to pass through, while keeping out toxins and bacteria. People with celiac disease have higher levels of zonulin, which apparently allows gluten to pass through the cells in their intestines, which triggers an autoimmune response in their bodies. Until now, researchers could never understand how a big protein like gluten could pass through the immune system. According to author Alessio Fasano, M.D., people with celiac have an increased level of zonulin, which opens the junctions between the cells. In essence, the gateways are stuck open, allowing gluten and other allergens to pass. Further: I believe that zonulin plays a critical role in the modulation of our immune system...(f)or some reason, the zonulin levels go out of whack, and that leads to autoimmune disease. Ultimately these finding may help doctors understand the causes of other, more severe autoimmune disorders.

    Very informative. Trust that the knowledge can be used in the future to help those with auto-immune disease.

    I've been a celiac since 1996 and love reading and informing other people about the disease. Keep up the investigated information. Thanks.

    Scott Adams was diagnosed with celiac disease in 1994, and, due to the nearly total lack of information available at that time, was forced to become an expert on the disease in order to recover. In 1995 he launched the site that later became Celiac.com to help as many people as possible with celiac disease get diagnosed so they can begin to live happy, healthy gluten-free lives.  He is co-author of the book Cereal Killers, and founder and publisher of the (formerly paper) newsletter Journal of Gluten Sensitivity. In 1998 he founded The Gluten-Free Mall which he sold in 2014. Celiac.com does not sell any products, and is 100% advertiser supported.

    Celiac.com 09/29/2006 - A new study identified a peptide which causes an immune reaction in a majority of active celiac disease patients but no such reaction in any celiac disease patients on a gluten-free diet. Antibodies to this celiac peptide also recognize and bind to the rotavirus protein VP-7 and cause increased intestinal permeability. Antibodies to VP-7 produced in rabbits also increase intestinal permeability. The celiac peptide also binds to Toll-like receptor 4 and activates monocytes (white blood cells active in innate immunity.) IgA and IgG antibodies to rotavirus protein VP-7 are present in a majority of celiac disease patients and to a much lesser percent of the general population. This suggests VP-7 may be involved in the pathogenesis of celiac disease through a...
