Alpha-gliadin (57–73) (Cat# 61899)
This 17-amino-acid peptide corresponds to the A-gliadin amino acids 57 to 73. Gliadin-reactive CD4+ T cells are present in the intestinal mucosa of patients with celiac disease (CD); a small intestinal disorder caused by adaptive and innate immune responses triggered by the gluten proteins present in wheat. Gluten-specific T cell response results in the production of antibodies against tissue transglutaminase (TG); which is shown to deamidate gliadin peptides. These modified gliadin peptides elicit a strong T-cell response in CD patients.
