Quantification of LXR protein in lung tissue sections. The distribution of LXRα (white bars) and LXRβ (grey bars) was quantified in the epithelium (A) and subepithelium (B) of small airways, the alveolar wall (C), in alveolar macrophages (D), and within lymphocytic aggregates (E). Data shown are mean ± SEM (A, C, and E) or median ± range (B and D) of 10 non-smoking controls (NS) (apart from E n=8), 10 smoking controls (S) (apart from E n=6) and 10 COPD patients (apart from E n=9). *, ** and *** = significant difference in protein levels (p<0.05, p<0.01 and p<0.001 respectively).
