| Outline of Final Research Achievements |
In the present study, we investigated the role of Nrf2 on an experimental model of Ovalbumin (OVA) - sensitized and challenged allergic airway inflammation in both of BALB/c and C57BL/6 mice.
Nrf2+/+ and Nrf2－/－ mice were used in both of BALB/c and C57BL/6 mice. Allergic airway inflammation was generated in the mice by intraperitoneal sensitization with OVA/alum, and the mice were challenged with OVA intranasally. The several parameters such as inflammatory cytokines, IgE, and anti-oxidation index were examined in the bronchoalveolar lavage (BAL) fluid, serum, and lung tissues.
In conclusion, the role of Nrf2 in the generation of allergic airway inflammation differs markedly between mouse strains. Our results suggest that Nrf2 may play a key role in the development of allergic airway inflammation related to neutrophils in Th2 type BALB/c mice.
