Densitometry analysis of reverse transcription polymerase chain reaction products of the (A) interleukin 13 receptor α2 (IL-13Rα2), (B) IL-13Rα1, and (C) IL-4Rα genes in upper and lower surgical lung biopsies (SLBs) from patients with idiopathic interstitial pneumonia and controls (mean control values, solid line; control SEM values, dashed lines). Data are means ± SEM; *p ⩽ 0.05, **p ⩽ 0.01 compared with the control SLBs. Note that cytokine receptor transcript values were identical in upper and lower lobe samples from the normal patient group so that a single mean and SEM value is shown for the normal patient group. NSIP, non-specific interstitial pneumonia; RBILD, respiratory bronchiolitic interstitial lung disease; UIP, usual interstitial pneumonia.
