Wheat gluten proteins, gliadins and glutenins, are of great importance in determining the unique biomechanical properties of wheat. Studies have therefore been carried out to determine their pathways and mechanisms of synthesis, folding, and deposition in protein bodies. In the present work, a set of transgenic wheat lines has been studied with strongly suppressed levels of γ-gliadins and/or al...
Gliadins, specified by six compound chromosomal loci (Gli-A1/B1/D1 and Gli-A2/B2/D2) in hexaploid bread wheat, are the dominant carriers of celiac disease (CD) epitopes. Because of their complexity, genome-wide characterization of gliadins is a strong challenge. Here, we approached this challenge by combining transcriptomic, proteomic and bioinformatic investigations. Through third-generation R...
To characterize and compare the protein quality of ten durum wheat genotypes grown under three cropping modalities in Algeria (subhumid Algiers, subhumid-semiarid Constantine, semiarid Sétif), profile their kernels was performed by High-Performance Liquid Chromatography (SE-HPLC RP-HPLC). The “variety” factor has a major impact, mainly on insoluble fraction (Fi), gliadin/glutenin ratio, large s...
In the present work the effects on dough quality by the down-regulation of γ-gliadins in different genetic backgrounds of bread wheat were investigated. RNAi-mediated silencing of γ-gliadins was introgressed by conventional crossing into three commercial bread wheat lines (namely 'Gazul', 'Podenco' and 'Arpain'), and along with the transgenic line A1152 (cv. Bobwhite) compared with their respec...
Coeliac disease (gluten enteropathy) is associated with a damaged gut mucosa displaying degraded villi and poor absorption of nutrients. The major symptoms are emaciation, swollen abdomen, poor growth, vomiting, diarrhoea and steatorrhea [I]. The condition affects 1 in 1850 individuals in the UK although the world-wide incidence is variable and depends upon the dietary use of wheat and similar ...
Background and Objectives Wheat gluten proteins make up one of the most complex protein aggregates in nature. Their qualitative quantitative composition is determined by genetic environmental factors as well technological processes. Findings Gluten comprise ?5-, ?1,2-, ?-, ?-gliadins high-molecular-weight glutenin subunits (HMW-GS) low-molecular-weight (LMW) GS. About 50% are monomeric gliadins...
BACKGROUND Gliadins are a major component of gluten proteins but their role in the mixing of dough is not well understood because their contribution to wheat flour functional properties are not as clear as for the glutenin fraction. METHODOLOGY/PRINCIPAL FINDINGS Transgenic lines of bread wheat with γ-gliadins suppressed by RNAi are reported. The effects on the gluten protein composition and ...
The aim of the present study was to characterize allergen-specific immunoglobulin E (IgE) among children in Fez region. Eighty one children were recruited from the Hospital University Center of Fez. All of them had completed a questionnaire before taking sera. The sera were used to measure total IgE and specific data to proteins of egg's white (EWP), peanuts (PP) and gliadins (G). In last part,...
A simple and fast immunoaffinity method is proposed for the determination of gliadins for the first time using gold nanoparticles (AuNPs) as labels. The tracer used consists in a gliadin-AuNP conjugate prepared by the adsorption of gliadins onto the nanoparticle surface. Two AuNP sizes with diameters of 10nm and 20 nm were assayed to compare the behaviour of the corresponding tracer in the assa...
The present work measured circulating antibodies against native gliadins, deamidated gliadin-derived epitopes, and transglutaminase 2 (TGM2) in 473 patients with schizophrenia and 478 control subjects among a Chinese population. The results showed that 27.1% of patients with schizophrenia were positive for the IgA antibody against native gliadins compared with 17.8% of control subjects (χ(2) = ...
