Identification of wheat proteins involved in active stage of celiac disease: are gamma gliadins the major disease-specific antigens?

چکیده
Methods We developed a method wherein the alcohol extracted gliadins was fractionated in two steps of ion-exchange chromatography, Sulphopropyl (SP) was used for the first step and the flow through (FT) fraction obtained was further fractionated using DEAE. Each generated fraction’s reactivity to serum IgA, from clinically well defined CD (active/diet) patients and non-CD patients was analyzed. Identification of disease specific antigens in the fractions was attempted using mass spectrometry and N-terminal sequencing.

A Universal Approach to Eliminate Antigenic Properties of Alpha-Gliadin Peptides in Celiac Disease
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 ...
متن کاملProduction of a panel of recombinant gliadins for the characterisation of T cell reactivity in coeliac disease.
BACKGROUND/AIMS Coeliac disease is a chronic intestinal disorder most probably caused by an abnormal immune reaction to wheat gliadin. The identification of the HLA-DQ2 and HLA-DQ8 as the molecules responsible for the HLA association in coeliac disease strongly implicates a role for CD4 T cells in disease pathogenesis. Indeed, CD4 T cells specific for gliadin have been isolated from the small i...
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...

BACKGROUND In celiac disease patients, peptides derived from dietary gluten are recognized by HLA-DQ2-restricted CD4(+) T cells, which results in inflammation. Such immune-stimulatory peptides are found in both gliadins and glutenins. Monoclonal antibodies (mAbs) against these peptides can be used to screen food for the presence of such peptides. OBJECTIVE We aimed to determine the specificit...

Introduction: Celiac disease (CD) is a hereditary disorder of the immune system which damages the mucosa of the small intestine caused by gluten consumption(even very small amounts). Villous atrophy, leads to malabsorption, which is due to decreased absorption levels. The first bowel symptoms are seen during the first 2 years of life. Currently, the only treatment is to compliance with a glut...
