| Research Abstract |
In this study, we examined the absorption pathway(s) of a representative food allergen, lysozyme, and the mechanisms of lysozyme absorption facilitated by non-steroidal anti-inflammatory drugs (NSAIDs) in rats. We showed that lysozyme was absorbed by endocytic and paracellular pathways in the proximal intestine, and the absorption was facilitated by aspirin and diclofenac after impairment of the paracellular pathway. Furthermore, we found that a synthetic prostaglandin-E1 analog, misoprostol suppressed the intestinal absorption of allergens facilitated by aspirin. These findings may help to clarify the pathophysiology of FDEIA and aid its treatment.
