T-bet and pSTAT-1: New Genetic Markers for Celiac Disease?

Celiac.com 01/18/2013 - Up-regulation of T-bet and phosphorylated signal transducers and activators of transcription (pSTAT)1 are key transcription factors for the development of T helper type 1 (Th1) cells, and have been found in the mucosa of patients with untreated celiac disease.

CC--Mervi EskelaninA team of researchers recently set out to determine if T-bet and pSTAT-1 expression in PBMC from celiac disease patients might offer new genetic markers of disease activity.

The research team included G. Frisullo, V. Nociti, R. Iorio, A.K. Patanella, D. Plantone, A. Bianco, A. Marti, G. Cammarota, P.A. Tonali, A.P. Batocchi. They are affiliated with the Department of Neurosciences at Catholic University in Rome, Italy.

For their study, the team used transcription factor analysis to determine whether T-bet and pSTAT1 expressions are up-regulated in the peripheral blood of celiac disease patients, and if they correlate with disease activity.

They used flow cytometry to analyse T-bet, pSTAT1 and pSTAT3 expression in CD4(+), CD8(+) T cells, CD19(+) B cells and monocytes from peripheral blood of 15 untreated and 15 treated celiac disease patients and 30 controls. They also conducted a longitudinal study of five celiac patients before and after treatment with a gluten-free diet.

For their evaluation, the team used enzyme-linked immunosorbent assay (ELISA), interferon (FN)-gamma, interleukin (IL)-17 and IL-10 production by peripheral blood mononuclear cell (PBMC) cultures.

They found that T-bet expression in CD4(+), CD8(+) T cells, CD19(+) B cells and monocytes and IFN-gamma production by PBMC was higher in untreated than in treated celiac disease patients and control subjects.

They also found that pSTAT1 expression was higher in CD4(+)T cells, B cells and monocytes from untreated celiac disease patients than from treated patients and control subjects.

Compared with treated celiac disease patients and control subjects, untreated patients showed increased pSTAT3 only in monocytes.

They confirmed their results using data obtained from the longitudinal evaluation of transcription factors.

From their results, they conclude that flow cytometric analysis of pSTAT1 and T-bet protein expression in peripheral blood mononuclear cells could be useful and sensible markers in the follow-up of celiac disease patients to evaluate disease activity and response to dietary treatment.

George, i am sorry that you are not feeling well! ?? I am not a doctor, but just trying out drugs to stop your symptoms just seems like a band aid approach. It sounds like he suspects IBS which is really, in my opinion, "I be stumped". Has inflammatory bowel disorder (IBD) (more lovely autoimmune disorders) been ruled out? This includes both Crohn's and Colitis. My niece was diagnosed with Crohn's finally with a pill camera after all other tests were given. The damage was not within reach of any scope. I am just throwing out suggestions. Hopefully, you and your doctor will figure it out soon!

Celiac disease is an autoimmune disease that happens to have a known trigger -- gluten. Flare-ups develop (antibodies) causing damage. Not just in the small intestine, but systemically. One gluten exposure can cause antibodies to increase for days or months! Antibodies are being measured during the celiac blood tests. If there is no gluten exposure, there will be no antibodies. These antibodies can come down in some people in as little as two weeks. Recommendations require gluten 2 to 4 weeks daily for the biopsies taken via endoscopy in order to be sure to catch damage, but 8 to 12 weeks for the blood tests. The endoscopy is considered the "gold standard" in helping to diagnose celiac disease, but there are other things that can damage the small intestine. So, the blood test helps solidify the diagnosis. So, if you want a good result on your endoscopy, you need to be eating gluten daily for two week prior at a minimum. I know it is tough and you are feeling sick. Wish there was a better way to catch active celiac disease.

Hi everyone, Just an update to my situation. I had thought that I might be getting better since I started adding gluten-free grain back into my diet but I was wrong. It seems that the Methscopalamine Bromide just delayed the effects, didn't stop them. I had to stop taking it because one of the side effects is to stop sweating, which I did. There were times when I felt hot and almost couldn't catch my breath. Anyway, my doc put me on Viberzi instead. I took 3 doses, 1 Tuesday evening and then 1 Wednesday morning and then again Wednesday evening. Each time I took 1, it seemed that about half an hour later I would develop severe abdominal cramping, pain in my neck, shoulders and upper back and a feeling like my insides were on fire. My face felt like it was hot and tingling. It wasn't warm to the touch but felt like it to me. Worse of all is it didn't work anyway, I still had diarrhea. I stopped taking Viberzi after reading the precautions pamphlet which said, "stop taking Viberzi and tell your doctor if you have abdominal cramping, pain which radiates to your shoulders or upper back." Go figure. Anyway, today is 3 weeks straight of diarrhea and still no diagnosis and not sure what he's going to want to do next. George

I'm still really new to all this but is it common to have trouble with sleep? I swear since my symptoms got really bad a few months ago I can't get 1 good nights sleep, like a 5 hour stretch is doing real good. Wake up at 3am wide awake almost every night. Told my doctor and they've recommended melatonin, that doesn't work. Tried chamomile and lavender tea, no help. Tried zzquil, that will knock me out but maybe for like an extra hour then I'm really drowsy the next morning from it. I don't know what to do.

I have 2 copies of DQ9. One from each parent.
