Transfer of IL-4Rα+/+ BMM leads to the presence of AAM in the lungs of mice. A. Lung sections from the OVA/alum primed mice shown in Figure 4 were stained with anti-F4/80, anti-YM1/2, or anti-CD3 as indicated. Images from a representative mouse from each group are shown at 10X or 20X as indicated. CD3+ cells appear brown. B. The CD3+ cells in each 20X field were counted (n = 5). The average number of CD3+ cells per field were calculated and graphed. Data represented as cell counts ± SEM. These results are representative of 3 independent experiments.
