SLAM−/− OVA mice have significantly reduced BAL eosinophils when compared with SLAM+/+ OVA mice. Each mouse underwent BAL after OVA sensitization and challenge as described in Materials and Methods. Cell counts were determined by differential staining of cells isolated from the BALF. Data are shown as percentage of total cells ± SEM (n = 2 experiments; 6–11 mice per group).
