Outline of Final Research Achievements

In this study, exposure of antigens to fetus or juvenile mice suppressed the induction of laboratory animal allergy. These results suggest incidence of laboratory animal allergy is influenced by environmental factors and the relationship between the influence and establishment of T cell repertory as T cell repertory is established in fetus or juvenile mice. Moreover, animal allergen Can f 1-specific IgE and IL13 levels in the mice immunized with Can f 1 were influenced by aluminum hydroxide, differing from the results for immunization with OVA as a food allergen. These results suggest that the immune mechanism for laboratory animal allergy is different from that with food allergy.
