E-mail: erika.jensen-jarolim@meduniwien.ac.at <h3>SPECIFIC AIMS</h3> Food allergens that are able to sensitize via the gastrointestinal tract are postulated to be digestion stable. We have observed that dietary proteins lead to allergic reactions in BALB/c mice only when their B cell epitopes are stabilized. Strikingly, some typical food allergens like fish, shrimp, and potato are easily degraded when subjected to simulated gastric fluid assays. Our consequent hypothesis was that proteins might exhibit allergenic capacity not only when digestion resistant, but also when simply surviving the
