    Celiac.com 08/07/2003 - This studys aim was to determine the feasibility of altering gluten proteins to make them harmless to those with celiac disease. Unfortunately the altered protein still produced a toxic T-cell reaction in almost half of the patients studied. Here is the abstract:

    Intestinal T-cell responses to high-molecular-weight glutenins in celiac disease.

    Molberg O, Solheim Flaete N, Jensen T, Lundin KE, Arentz-Hansen H, Anderson OD, Kjersti Uhlen A, Sollid LM.

    BACKGROUND & AIMS: The chronic, small intestinal inflammation that defines celiac disease is initiated by a HLA-DQ2 restricted T-cell response to ingested gluten peptides after their in vivo examination by tissue transglutaminase (TG2). To date, celiac disease can only be treated by a lifelong abstinence from foods that contain wheat, rye, or barley; better therapeutic options are hence needed. An attractive target would be to identify nontoxic wheat cultivars or components thereof with intact baking qualities. Because these qualities are mainly determined by the high molecular weight (HMW) glutenin proteins of gluten, it is critical to know if these proteins are toxic or, more specifically, if they will trigger the activation of T cells in the celiac lesion.

    METHODS: Different, highly purified HMW glutenins were isolated from wheat cultivars or expressed as recombinant proteins. The proteins were first tested for recognition by a large panel of gluten-specific T-cell lines established from celiac lesions and then applied during ex vivo challenges of celiac biopsies to allow for a direct identification of HMW specific T cells.

    RESULTS: Intestinal T-cell responses to TG2-deamidated HMW glutenins but not the corresponding native proteins were detectable in 9 of the 22 adult and childhood celiac disease patients tested.

    CONCLUSIONS: T cells within celiac lesions frequently recognize deamidated HMW glutenin proteins. This finding questions the possibility of implementing these proteins in novel food items destined to be nontoxic for celiac disease patients.

  • About Me

    Celiac.com's Founder and CEO, Scott 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. Scott launched the site that later became Celiac.com in 1995 "To help as many people as possible with celiac disease get diagnosed so they can begin to live happy, healthy gluten-free lives."  In 1998 he founded The Gluten-Free Mall which he sold in 2014. He is co-author of the book Cereal Killers, and founder and publisher of Journal of Gluten Sensitivity.
