Gluten protein components and the role of its subgroups in GRDs pathogenesis. According to the results of studies α and γ-gliadins and glutenin are considered to be CD pathogenic responses eliciting factors. The α-gliadin fraction is also reported as DH immunological response triggering agent. Allergic reactivity to the α-/β-, γ- and ω- gliadin fractions and LMW-GS was observed in WA patients. Moreover, patients with NCGS revealed high levels of IgG antibodies against α-, γ- and ω-gliadin and glutenin.
