Effect of lactoferrin (LTF) on ragweed pollen (RWE)-induced accumulation of inflammatory cells into subepithelium. Mice challenged with RWE demonstrated high-inflammatory cell infiltrates within peribronchial region (arrows) postchallenge (left), but not in the LTF-treated mice (right). Sections were stained with hematoxylin and eosin and visualized at 100× magnification. Photomicrographs were previously described in detail, and represent studies published in Kruzel et al. (38).
