Representative photomicrographs of small airways of the control group (A and C) and patients with ARDS (B and D) stained with anti–IL-8 (A and B) and anti–IL-6 (C,D). There is higher expression of IL-8 in the airway epithelium and a higher number of IL-6– and IL-8–positive inflammatory cells (arrows) in the airway walls in the ARDS group. L, lumen; EP, respiratory epithelium; scale bar, 50 μm.
