Enzyme linked immunosorbent assay analysis of (A) interleukin 13 (IL-13), (B) IL-4, and (C) interferon γ (IFNγ) protein concentrations in surgical lung biopsies (SLBs) from patients with idiopathic interstitial pneumonia (IIP) (bars) and normal patient groups (solid (mean level) and dashed lines (SEM)). Data are mean ± SEM; *p ⩽ 0.05, **p ⩽ 0.01 compared with the indicated upper or lower lobe SLBs from all other IIP and normal patient groups (asterisks above the bars). Note that cytokine values were identical in upper and lower lobe samples from the normal patient group so that a single mean and SEM is shown for this group. NSIP, non-specific interstitial pneumonia; RBILD, respiratory bronchiolitic interstitial lung disease; UIP, usual interstitial pneumonia.
