| Research Abstract |
We have reported that increase of allergen absorption is one of factors which enhance the allergic symptoms in patients with wheat-dependent exercise-induced anaphylaxis. In this study, we investigate the method to evaluate the allergenicity of peripheral blood food allergen by beta-hexosaminidase assay in rat basophil leukemia cells (RBL-2H3). Degranulation of RBL-2H3 cells sensitized with the sera from Brown Norway rat having allergen specific-IgE was observed, suggesting that the biological activity of allergen in the blood could be estimated by using the method. In addition, we identified gamma-gliadin as a major allergen and its IgE-binding epitope in WDEIA induced by a soap containing hydrolyzed wheat.
