General description

Gliadin is a protein found in wheat and other cereals. The T cells recognize the gliadin epitopes and activate the innate immune response similar to the response to pathogens. This response is more intense in coeliac disease wherein the gut-derived T cells produced in response to gliadin induce damage to the small intestine. Therefore, patients affected by coeliac disease or gluten-sensitivity should avoid food that produce gliadin
Gliadin is an important component of wheat gluten. It is composed of single-chain polypeptides and has a molecular weight of 25−100 kDa. It is associated by intramolecular disulfide bonds.

Specificity

Rabbit Anti-Gliadin shows specificity for native wheat gliadin.

Immunogen

native and heat-treated wheat gliadin

Application

Anti-Gliadin (Wheat) antibody produced in rabbit has been used in immunoblot and enzyme-linked immunosorbent assay (ELISA).

Biochem/physiol Actions

Gliadin is a class of glutamine containing, alcohol soluble proteins separable from wheat and rye glutens known as the prolamins. These proteins are associated with the harmful effects of celiac disease and gluten sensitive enteropathy in humans, causing characteristic changes in the small intestinal mucosa. In such cases, strict compliance to a gluten-free diet is usually recommended.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide

Celiac disease could be treated, and potentially cured, by restoring T-cell tolerance to gliadin. We investigated the safety and efficacy of negatively charged 500-nm poly(lactide-co-glycolide) nanoparticles encapsulating gliadin protein (TIMP-GLIA) in 3 mouse models of celiac disease. Uptake of these

Gluten is the ethanol-soluble protein fraction of cereal endosperms like wheat, rye, and barley. It is widely used in the food industry because of the physical-chemical properties it gives to dough. Nevertheless, there are some gluten-related diseases that are presenting
