Altered Gluten Proteins Still Trigger Intestinal T-cell Responses in Celiacs

Gastroenterology. 2003 Aug;125(2):337-344.

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.

Hi Stephanie, I'm also from the UK, I've found this site more helpful than anything we have! As already mentioned above, in my experience it could depend on what and where you were drinking. Gluten free food and drink isn't always (not usually) 100% gluten free as you may know, maybe you have become more sensitive to even a trace of gluten that is probably in gluten free food/drink. Is it possible you have a problem with corn, particularly high fructose corn syrup that is in a lot of alcoholic drinks? This was a big problem for me and the only alcoholic drinks I can tolerate are William Chase vodka and gin. I contacted the company last year and all their drinks are 100% gluten and corn free, made the old fashioned way with no additives, so maybe try their products if you like the occasional drink and see how you get on. If you drink out, not many pubs sell their products but I know Wetherspoons do and smaller wine bars may too. l was never a spirit drinker but I must say their products are absolutely lovely! Very easy on a compromised gut too considering it's alcohol. I second the suggestion on seeing a natural health practitioner. I've recently started seeing a medical herbalist, as I've got nowhere with my now many food intolerances since going gluten free last year and I've noticed a difference in my health already.

Sorry for the very late reply and thanks for the replies, I didn't get a notification of any. In case anyone else comes across this and has been wondering the same as I was, I did try a vegetable broth and I did react to it in the same way as if I'd eaten the vegetables. As for the candida, I've been using coconut oil and am seeing a medical herbalist for this and leaky gut. It's only been a few weeks but I've noticed an improvement all round.

What did you drink and where did you drink it? NOTE if you drink something at a bar using their glasses your asking for trouble BEER IS EVERYWHERE in most bars and a CC hell. If it was at home and a non grain based liqour then I would be really concerned that it might just be alcohol. I personally can not really drink much of anything any more. I love rum, and I cook with it sometimes in sautes. I also have rum extract/butter rum extract/and rum emulsion I use in shakes, homemade keto pudding/ mixed into dishes. and even add some to drink to give it a rum flavor lol.

I can only think of two things, 1 something you put on your potato was contaminated like the butter container could have crumbs in it or something like that as mentioned before, and you could be having a reaction to dairy or what ever was put in it.......IF it was just plain potato and you reacted with bloating and cramping you might have a carb issues, tad rare and most associated with additional auto immune diseases but could be in which case a diet of fats and protein would be your answer much like it is for me now days. What all have you eaten in the privous 8 hours including beverages, condiments, spices and foods?

They are gluten-free. Did you use butter that might have gluten crumbs on it? For me , it takes more than 2 hours to feel the effect of gluten- maybe something you ate before? Maybe stomach virus?
