Figure 7

Effect of NOD1 and NOD2 ligands on the morphology of bronchial tissues in allergic asthmatic mice. Fixed lung tissue sections were stained with PAS to evaluate the mucin-producing goblet cells and general morphology of lung tissues from mice with different treatments and representative staining figures were shown. Arrows in digital photomicrographs (×10 magnification) denote mucin-producing goblet cells stained with bright purple. PBS: PBS control; OVA: ovalbumin. NOD, nucleotide-binding oligomerization domain; PAS, periodic acid Schiff; PBS, phosphate-buffered saline.
