A link between celiac disease and schizophrenia has been postulated for several years, based primarily on reports of elevated levels of antibody to gliadin in patients. We sought to examine the proposed connection between schizophrenia and celiac disease by characterizing the molecular specificity and mechanism of the anti-gliadin immune response in a subset of individuals with schizophrenia. B...
Gliadin triggers T-cell mediated immunity in celiac disease, and has cytotoxic effects on enterocytes mediated through obscure mechanisms. In addition, gliadin transport mechanisms, potential cell surface receptors and gliadin-activated downstream signaling pathways are not completely understood. In order to screen for novel downstream gliadin target genes we performed a systematic whole genome...
The agglutinating properties of a crude gluten digest, purified gliadin fractions and established plant lectins were investigated using mammalian erythrocytes, rat enterocytes and normal and coeliac human enterocytes as the target systems. Gliadin preparations failed to cause agglutination of any of the cells tested, whereas established pure plant lectins were active cell agglutinins. These stu...
BACKGROUND AND AIMS Despite the progress made in understanding the immunological aspects of the pathogenesis of coeliac disease (CD), the early steps that allow gliadin to cross the intestinal barrier are still largely unknown. The aim of this study was to establish whether gliadin activates a zonulin dependent enterocyte intracellular signalling pathway(s) leading to increased intestinal perme...
This work develops a label-free gliadin immunosensor that is based on changes in the frequency of a quartz crystal microbalance (QCM) chip. A higher sensitivity was obtained by applying 25 nm gold nanoparticles (AuNPs) to the surface of a bare QCM electrode. Subsequently, chicken anti-gliadin antibodies (IgY) were immobilized directly on the AuNP-modified surface by cross-linking amine groups i...
The diagnostic value of measuring alpha gliadin antibodies in children with suspected coeliac disease has been evaluated prospectively. Jejunal biopsy and alpha gliadin antibody measurements were performed in 77 consecutive children who were being investigated for a suspected malabsorption syndrome. The typical small intestinal histological lesion of coeliac disease was found, and this diagnosi...
An improved technique for the detection of alpha-gliadin sensitised mononuclear cells in the peripheral blood of untreated coeliac patients is described. This method is a modification of the direct LMIF assay, and involves exposure of lymphocytes to alpha-gliadin and the assay of the resultant lymphokine produced using normal leucocytes as indicator cells. All untreated coeliac patients, 14 of ...
Celiac disease is an immune-mediated disorder triggered by ingestion of wheat gliadin and related proteins in genetically susceptible individuals. In addition to the characteristic enteropathy, celiac disease is associated with various extraintestinal manifestations, including neurologic complications such as neuropathy, ataxia, seizures, and neurobehavioral changes. The cause of the neurologic...
در این رساله، وجود و چندگانگی جواب های مثبت دسته ای از معادلات و دستگاه معادلات دیفرانسیل با مشتقات جزئی غیرخطی با شرط های مرزی همگن دیریکله را بر اساس روش جواب های پایینی-بالایی در دو مفهوم کلاسیک و ضعیف مورد بحث قرار می دهیم. فرض کنید $omega$ دامنه ای کراندار در $mathbb{r}^n$ با مرز هموار $partial omega$ است. ابتدا، وجود جواب های مثبت مسائل نیمه مثبت گون نامتناهی [ -delta u=-a ...
Celiac disease and typel diabetes mellirus have been linked to the same HLA markers and chromosomal loci, which may account for the concurrence of the two disorders in a significant number of patients. This study was designed to investigate the frequency of anti-gliadin antibodies, a marker for celiac disease, in diabetic patients.Methods: In this study, 182 diabetic patients (52 with typel and...
