In non-obese diabetic (NOD) mice, diabetes incidence is reduced by a gluten-free diet. Gluten peptides, such as the compound gliadin, can cross the intestinal barrier and may directly affect pancreatic beta cells. We investigated the effects of enzymatically-digested gliadin in NOD mice, INS-1E cells and rat islets. Six injections of gliadin digest in 6-week-old NOD mice did not affect diabetes...

OBJECTIVE Recent research suggests that oats do not harm intestinal villi in adults with coeliac disease. As the immunological effects of oats have not been examined in detail, it was decided to compare the immunological responses of a gluten free diet including oats with those of a conventional gluten free diet. DESIGN A randomised controlled intervention study over 6-12 months. SUBJECTS F...

Class II major histocompatibility molecules confer disease risk in Celiac disease (CD) by presenting gliadin peptides to CD4 T cells in the small intestine. Deamidation of gliadin peptides by tissue transglutaminase creates immunogenic peptides presented by HLA-DQ2 and DQ8 molecules to activate proinflammatory CD4 T cells. Detecting gliadin specific T cell responses from the peripheral blood ha...

OBJECTIVE To characterize humoral response to cerebellum in patients with gluten ataxia. BACKGROUND Gluten ataxia is a common neurologic manifestation of gluten sensitivity. METHODS The authors assessed the reactivity of sera from patients with gluten ataxia (13), newly diagnosed patients with celiac disease without neurologic dysfunction (24), patients with other causes of cerebellar degen...

Celiac Disease (CD) is an autoimmune disorder, represented by the ingestion of gliadin protein usually found in wheat, barley and rye. CD is closely associated with genes that code HLA-II antigens, mainly of DQ2 and DQ8 classes. Small intestinal biopsy is considered the gold standard for diagnosis of celiac disease. In addition, the most sensitive tests for the diagnosis of celiac disease inclu...

Dietary antioxidant supplementation has been popular in Western countries. Various supplements have been developed in recent years, and research has been gathered from both animal and clinical research trials. In this review, the therapeutic value of oral administration of a combination of melon superoxide dismutase (SOD) and a vegetable polymer (gliadin) is evaluated. Critical examination of t...

1. Gliadin from which carbohydrate was removed by treatment with carbohydrase from Aspergillus niger was fed to three coeliac patients in remission. 2. Xylose absorption, mucosal morphology and brush-border enzymes were used to assess the toxicity of the carbohydrase-treated gliadin. 3. Gliadin treated with carbohydrases did not damage the intestinal mucosa of the coeliac patients. 4. The prima...

Because of the possible clinical association between coeliac disease and sarcoidosis, the incidence of humoral sensitivity to dietary proteins was examined in patients with sarcoidosis. Raised concentrations of circulating IgG antibodies to alpha gliadin were found in 41/99 sarcoid patients whereas antibody levels to casein, beta lactoglobulin and ovalbumin were similar to normal controls. Subs...

Our aim in this study was to determine soluble tumor necrosis factor (TNF)-like weak inducer of apoptosis (sTWEAK) and interleukin-17A (IL-17A) levels in celiac disease, and their association with the gluten diet and autoantibodies. Eighty patients with celiac diagnosis and 80 healthy control individuals with similar age, gender and body mass index to the patient group were included in the stud...
