Gliadin intolerance of wheat, barley and rye – all of which contain prolamins. Gliadin proteins have the ability to provoke an autoimmune enteropathy caused by an abnormal immune response in genetically susceptible individuals. Specific amino acid sequences within the gliadin proteins are responsible for this activity. The main problems with this disease is that it often goes unrecognized for many years, in which it can cause serious damage to several organs, and most cases currently remain unrecognized, undiagnosed and untreated. Mainly intestinal villi destruction mediated by Interferon Gamma and CD 4(+). Celiac disease with "non-classic symptoms" is the most common clinical
Gluten immunochemistry its genome contains chromosomes derived from two goat grass species and a primitive wheat species. The positions of these motifs in different species, strains and isoforms may vary because of insertions and deletions in sequence. There are a large number of wheat variants, and a large number of gliadins in each variant, and thus many potential sites. These proteins once identified and sequenced can be surveyed by sequence homology searches. HLA-DQ recognition of gliadin is critical to the pathogenesis of gluten-sensitive enteropathy, it also appears to be involved in idiopathic gluten sensitivity (See:Understanding DQ Haplotypes and DQ isoforms on the
