(a)
HAMP mRNA (non-smoker n = 5, smoker n = 6, COPD n = 9), (b)
SLC40A1 mRNA (non-smoker n = 5, smoker n = 6, COPD n = 8) expression levels in lung-derived macrophages from lung tissue macrophages isolated from lung parenchyma. (c)
HAMP mRNA (non-smoker n = 7, smoker n = 5, COPD n = 8) and (d)
SLC40A1 mRNA (non-smoker n = 7, smoker n = 6, COPD n = 9) expression levels of monocyte derived macrophages generated from monocytes isolated from peripheral blood mononuclear cells stimulated with granulocyte-macrophage colony stimulating factor (2 ng/ml GM-CSF for 12 days). All data are mean ± s.e.m. *P < 0.05 by Kruskall-Wallis followed by Dunn’s post-hoc test.
