Gluten immunochemistry those detected in celiac disease bind to the α-2 gliadin(57-73). This site is within the T-cell reactive "33mer" presented by DQ2.5. There has been some suggestion wheat plays a role in juvenile diabetes as antibodies to the non-glutinous seed storage glb-1 (a globulin) are implicated in crossreactive autoantigenic antibodies that destroy islet cells in the pancreas. Anti-gliadin antibodies have been found to synapsin I Omega-gliadin and the HMW Glutenin subunit antibodies have been found most commonly in individuals with exercise-induced anaphylaxis and Baker's allergy, and represent a potent class of gluten allergens. Non-glutinous proteins in wheat are also allergens, these
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
