Using Non-Inflammatory Gluten Peptide Analogs as Biomarkers for Celiac Disease

Celiac.com 09/30/2009 - Are non-inflammatory gluten peptide analogs effective as biomarkers for celiac disease? Recent research indicates that they just might represent an effective new tool in the management of celiac disease.

In the August 28th issue of Chemical Biology, a team of researchers from Stanford University's Department of Biochemistry issues a call for new tools to manage celiac disease, a lifelong immune disease of the small intestine. Non-inflammatory gluten peptide analogs may be one of the important new tools in that effort.

The research team is made up of M. T. Bethune, M. Crespo-Bosque, E. Bergseng, K. Mazumdar, L. Doyle, K. Sestak, L. M. Sollid, and C. Khosla.

They note that current drug trials are sparking a researchers to seek non-invasive biomarkers of gluten-induced intestinal change.  They note also that they have synthesized and characterized non-inflammatory gluten peptide analogs in which Asn or His replace key Gln residues.

As with their pro-inflammatory associates, these genetic markers resist gastrointestinal proteases, are susceptible to glutenases, and permeable across enterocyte barriers.

In contrast with gluten peptides, however, the markers are not commonly acknowledged by transglutaminase, HLA-DQ2, or disease-specific T cells.

In vitro and animal tests prove that the biomarkers can reveal shifts in intestinal permeability as well as glutenase-catalyzed gastric detoxification of gluten.

As a result, they call for controlled clinical studies to assess the use of these peptides as markers for abnormal intestinal permeability in celiac patients and for the effectiveness of glutenase in clinical trial and treatment of celiac disease.

Hi! My daughter is 19 was diagnosed at age 16. It took about 12-18 month s for her to fully heal from the damage and feel "normal" again. Also because of the damage done she had reactions to dairy, so you may want to try no or minimum dairy until youre fully healed. Just a suggestion. Hope you start feeling well soon!

Hi yall! New to this blog, but really glad it exists because I have lots of questions. First off, I'm Allie! I'm 17 and newly diagnosed Celiac after about 3 years of searching for answers. I initially went gluten-free on the recommendation of a friend, I felt better in about a month and then my pediatric gastroenterologist had me do the gluten challenge, and my symptoms were the worst they have ever been, and ones I barely noticed before became very present. I did the biopsy and was diagnosed, it's been about 2 weeks and my symptoms are still pretty bad, although my diet has no known sources of gluten or cross contamination. Wondering if anyone has any input on healing post gluten challenge, any tips or how long it took for you would be quite helpful! Thanks

Might want to look into a keto diet, I have UC on top of celiacs and keto is working great Yeah I have major nerve and brain issues with gluten, gluten ataxia with nerve issues and brain issues. Seems to cause my body to attack my brain and nerve system. My brain stumbles fogs, and starts looping, the confusion causes me to become really irritable, I call it going Mr Hyde. Like my mind will start looping constantly on thoughts and not move driving me literally mad, or it used to. Now days it is primary the numbness anger but the gut issues and sometimes random motor loss limit me motionless to the floor now days for the duration of the major anger effects. Used to be a lot more mental then painful gut. I did a mental trauma post on it on while back where I came out about all my mental issues with gluten.

^^^^^^ good info, tips and tricks^^^^^^^^^ yes, crumbs will make you sick. also, breathing flour/pancake mix, etc that is in the air because eventually, you're going to swallow some.

Hello I was diagnosed Dec 15 of last year and went totally gluten-free the next day. I actually got worse before I got better - it's a steep learning curve - but now, 4 1/2 months later I'm finally seeing improvement. Hang in there.
