Figure 5.

Both knockout mice show increased inflammation and mucus secretion post OVA compared to WT. Paraffin sections of lungs of OVA-treated mice were stained with A, Hematoxyline and eosin (10×), B. with Masson's Trichrome stain (20×), and C. Alcian blue counterstained with eosin (10×). Sections were viewed with a BX4l Olympus microscope and photomicrographs taken with a Nikon Spot digital camera. Inflammatory cell migration was more pronounced around airways in the OVA-treated knockout mice compared to control.
