Figure 3: Cell counts and differentials from bronchoalveolar lavage Neutrophils dominated the BALF after a single OVA challenge (green bars, Short Challenge). Eosinophils dominated the BALF after 3 exposures to OVA (blue bars, Standard Challenge). After a recall challenge, the BALF had a mix of neutrophils and eosinophils (red bars, Recall Challenge). Neither challenge protocol generated significant levels of lymphocytes. **p<0.01, ***p<0.001, ****p<0.0001.
