Enzymatic hydrolysis of gluten proteins changes the dose-response of oral sensitization, but not the gluten epitopes

چکیده
Background Wheat gluten proteins are very complex proteins containing hundreds of components present as monomers, oligomers and polymers that by definition are not soluble in water. To improve utilization, gluten proteins can be hydrolyzed by enzymes or acid. This increases solubility and provide proteins with new functional properties. During the last decade, cases of severe allergic reaction to hydrolyzed wheat proteins have been reported in subjects tolerant to wheat.

Acid Hydrolysis of Wheat Gluten Induces Formation of New Epitopes but Does Not Enhance Sensitizing Capacity by the Oral Route: A Study in “Gluten Free” Brown Norway Rats
BACKGROUND Acid hydrolyzed wheat proteins (HWPs) are used in the food and cosmetic industry as emulsifiers. Cases of severe food allergic reactions caused by HWPs have been reported. Recent data suggest that these reactions are caused by HWPs produced by acid hydrolysis. OBJECTIVES To examine the sensitizing capacity of gluten proteins per se when altered by acid or enzymatic hydrolysis relat...
متن کاملRefractory Celiac Disease
Refractory celiac disease (RCD) is when malabsorption symptoms and villous atrophy persist despite strict adherence to a gluten free diet (GFD) for more than 12 months and other causes of villous atrophy have been ruled out. RCD is considered a rare disease and almost exclusively occurs in adults. Persistent diarrhea, abdominal pain, weight loss are the most common symptoms in RCD. Also, anemi...
متن کاملGluten - Not a Friendly Protein
Introduction: Gluten is a protein found in grains. Research has shown that the gluten that is in grains of wheat, barley, rye, and oats (to a lesser degree) is toxic to many individuals. While gluten is essential for the make-up of these 4 grains, our bodies do not need it. Is it healthful? The protein in today’s wheat is poorly digested and can be harmful. An estimated 95% of prepared fo...
متن کاملMolecular basis of celiac disease.
Celiac disease (CD) is an intestinal disorder with multifactorial etiology. HLA and non-HLA genes together with gluten and possibly additional environmental factors are involved in disease development. Evidence suggests that CD4(+) T cells are central in controlling an immune response to gluten that causes the immunopathology, but the actual mechanisms responsible for the tissue damage are as y...
متن کاملEnzymatic Strategies to Detoxify Gluten: Implications for Celiac Disease
Celiac disease is a permanent intolerance to the gliadin fraction of wheat gluten and to similar barley and rye proteins that occurs in genetically susceptible subjects. After ingestion, degraded gluten proteins reach the small intestine and trigger an inappropriate T cell-mediated immune response, which can result in intestinal mucosal inflammation and extraintestinal manifestations. To date, ...
