Relationships between SR-A mRNA, and cytokine expression levels and FEV₁% predicted.

Notes: Correlations between FEV₁% predicted, IL-8 expression level, TNF-α expression level and SR-A mRNA level in AMs. There were significantly negative correlations between SR-A mRNA levels in AMs and FEV₁% predicted in COPD patients (A). In addition, there were significantly positive correlations between SR-A mRNA levels and IL-8 expression levels, the same as SR-A mRNA levels and TNF-α expression levels (B, C). Data are expressed as mean ± SEM.

Abbreviations: AMs, alveolar macrophages; SEM, standard error of the mean; SR-A, class A scavenger receptor.
