Expression of LL-37 in small airways from non-smokers, smokers, and smokers with COPD. (a) Photomicrographs of immunohistochemistry for LL-37 in small airways from non-smokers (A), smokers (B), and smokers with COPD (C) (all images are × 400 magnification, scale bars=50 μm). (b) Quantification of LL-37 immunoreactivity in small airway epithelium (mean staining density).
