Celiac disease (CD) occurs frequently, and is caused by ingestion of prolamins from cereals in subjects with a genetic predisposition. The small intestinal damage depends on an intestinal stress/innate immune response to certain gliadin peptides (e.g., A-gliadin P31-43) in association with an adaptive immune response to other gliadin peptides (e.g., A-gliadin P57-68). Gliadin and peptide P31-43...
The wheat gluten protein alpha-gliadin, a well known trigger of celiac disease, can be complexed by random copolymers of hydroxyethyl methacrylate (HEMA) and sodium 4-styrene sulfonate (SS). In this work, influence of alpha-gliadin and poly(HEMA-co-SS) concentrations on alpha-gliadin structure was studied using spectroscopic techniques and dynamic light scattering. In 70% ethanol or 0.06M HCl (...
The aim of this study is to determine the effect of proteins from cereals and legumes on heme iron (Fe) absorption. The absorption of heme Fe without its native globin was measured. Thirty adult females participated in two experimental studies (15 per study). Study I focused on the effects of cereal proteins (zein, gliadin and glutelin) and study II on the effects of legume proteins (soy, pea a...
Nanoscale drug carriers play an important role in regulating the delivery, permeability, and retention of the drugs. Although various carriers have been used to encapsulate anticancer drugs, natural biomaterials are of great benefit for delivery and controlled release of drugs. We used the electrospray deposition system to synthesize gliadin and gliadin-gelatin composite nanoparticles for deliv...
Cereal Chem. 76(4):548–551 The complete amino acid sequence of an α-type gliadin from spelt wheat (spelta) has been deduced from the cloned DNA sequence and compared with α-type gliadin sequences from bread wheat. The comparison showed only minor differences in amino acid sequences between the α-type gliadin from bread wheat and the α-type gliadin from spelta. The two sequences had an identity ...
Wheat gliadin is known mainly as the causative substance for enteropathy accompanied by diarrhea (celiac disease) and food-dependent exercise-induced anaphylaxis. However, little is known in regards to the allergenicity of gliadin in atopic dermatitis. In this study, the allergenicity of gliadin was demonstrated using sera of wheat-allergic patients with atopic dermatitis. Since there are many ...
background: alopecia areata (aa) is a noncicatricial (nonscarring) alopecia. the association between aa and celiac disease (cd) is debatable. several studies declare the relationship between aa and cd as measurement of celiac autoantibodies (anti‑gliadin iga and anti‑gliadin igg), but a few studies consider anti‑tissue transglutaminase iga. the aim of this study was to evaluate the frequency di...
Wheat gluten includes two major proteins classes, gliadin (25–60 kg/mol) and glutenin polymers (100 to > 2,000 each comprising several polypeptides routinely identified by size-exclusion chromatography electrophoresis. Gluten are rich in glutamine (30%) contain repeated sequences, linking them the wide class of intrinsically disordered protein (IDP). Here we showed that an ethanol/water (EtOH/W...
The effects of wheat bug infestation (Eurygaster spp. and Aelia spp.) on the composition of wheat gluten proteins and its influence on flour technological quality were investigated in the present study. Wheat samples of six wheat varieties, collected from two localities in northern Serbia, were characterized by significantly different level of wheat bug infestation. Composition of wheat gluten ...
In this study Escherichia coli DE3 containing expression vector (pET21a) with cloned Persian sturgeon growth hormone (psGH) gene was grown in 10 mL LB broth on a 150 rpm shaker, at the temperature of 37 °C. At the late log phase (determined by OD standard curve) 100 &muL isopropyl &beta-D-1-thiogalactopyranoside (IPTG) was added for induction of GH synthesis. Samples were taken every 2 hours an...
