In cell differential counts, OVA stimulated Tg(−) group (OVA/Tg(−)) showed substantial eosinophilic airway inflammation, while the number of eosinophils in the BAL of OVA treated IL-22 Tg(+) (OVA/Tg(+)) group was significantly less compared to the OVA/Tg(−) group (Figure 3C). This evidence concerns the gene IL22 and inflammatory response.
