The identification of gluten peptides eliciting intestinal T cell responses is crucial for the design of a peptide-based immunotherapy in celiac disease (CD). To date, several gluten peptides have been identified to be active in CD. In the present study, we investigated the recognition profile of gluten immunogenic peptides in adult HLA-DQ2(+) celiac patients. Polyclonal, gliadin-reactive T cel...
Background and Objective: Preparation of proper antigens is an important issue in serology of hydatidosis. Investigators have been able to obtain excretory/secretory antigens (E/S Ags) by short-term culture of protoscoleces in a couple of culture media. However, no data are available about production rate of such antigens in different culture media. The present study was carried out to evaluate...
expression of htlv-i p19 protein in an escherichia coli expression system always leads to the formation of inclusion body. solubilisation and refolding of the inclusion bodies is complex, time consuming and difficult during large-scale preparation. this study aimed to express and purify a soluble form of recombinant htlv-i p19 protein in an e. coli expression system. the synthetic dna encoding ...
New assays for antibodies to deamidated gliadin peptides (DGP) expressing celiac disease-specific epitopes were evaluated using 154 sera previously tested for endomysial immunoglobulin A (IgA) (EMA), transglutaminase IgA (TGA), and conventional gliadin antibodies. DGP antibody results showed 97% concordance with EMA and TGA results. Of 56 sera negative for EMA and TGA but positive for conventio...
Linear and non-linear rheological properties of wheat gliadin and glutenin suspensions were investigated at various concentrations. Linear dynamic viscoelastic properties for both gliadin and glutenin were strongly dependent on concentration. For gliadins, the storage moduli (G 0), loss moduli (G00), and phase shifts dramatically changed within a narrow concentration range, indicating that glia...
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 ...
background : boophilus annulatus is an obligate blood feeder tick that can cause great losses in animals due to anemia and its ability to injure its host skin directly. the aim of this study was identification of cattle humoral immune response to some tick proteins during experimental infestation. methods : immune sera against tick were collected from experimentally infested cattle with ticks. ...
BACKGROUND Celiac disease (CD) is induced by wheat gliadins and related cereal proteins. Anti-gliadin antibodies (AGAs) are present in the serum of CD patients, but these antibodies have lower diagnostic specificity and sensitivity than autoantibodies [anti-endomysium antibodies (AEmAs) and anti-tissue transglutaminase antibodies (AtTGAs)]. Recently, AGAs from CD patients were found to recogniz...
Celiac disease is caused by an uncontrolled immune response to gluten, a heterogeneous mixture of wheat storage proteins, including the α-gliadins. It has been shown that α-gliadins harbor several major epitopes involved in the disease pathogenesis. A major step towards elimination of gluten toxicity for celiac disease patients would thus be the elimination of such epitopes from α-gliadins. We ...
Coeliac disease is an autoimmune disorder triggered in genetically predisposed individuals by the ingestion of gluten proteins from wheat, barley and rye. The α-gliadin gene family of wheat contains four highly stimulatory peptides, of which the 33-mer is the main immunodominant peptide in patients with coeliac. We designed two sgRNAs to target a conserved region adjacent to the coding sequence...
