From: CD8 positive T cells express IL-17 in patients with chronic obstructive pulmonary disease
IL-17A and IL-17F expression in COPD patients. (A) Immunohistochemistry, positive staining appears brown color. Magnification, 100 ×. Scale bar = 50 μm. (B) IL-17F expression in epithelium of airways of COPD patients. IL-17F positive area in epithelium was measured as outlined in text. (C) IL-17A and IL-17F expression in submucosa of airways of COPD patients. Absolute IL-17A+ and IL-17F+ positive cells in submucosa were counted. Results are expressed as median (range), n = 15 and 16 subjects for controls and COPD patients respectively. ***P < 0.0001.
