LXRα and LXRβ mRNA expression in whole lung tissue and lung macrophages. The expression of LXRα mRNA (A and C) and LXRβ mRNA (B and D) in whole lung tissue (A and B) and lung macrophages (C and D) from 10 non-smoking controls (NS), 10 smoking controls (S) and 10 COPD patients. Data shown are median ± range of relative LXRα/β expression levels. *, ** = Significantly increased expression above NS (p<0.05, p<0.01 respectively).
