From: Expression of MATE1, P-gp, OCTN1 and OCTN2, in epithelial and immune cells in the lung of COPD and healthy individuals

Fig. 2

P-gp protein expression in airway and alveolar epithelial cells and in alveolar macrophages. Paraffin sections of human lung tissue from healthy individuals (left column) and ex-smokers with COPD (right column) were immunostained with anti- P-gp antibody (brown) and counterstained with hematoxylin (blue). a and b show P-gp positive signals in epithelial cells in bronchi (arrow heads). c and d show P-gp staining in the bronchiolar epithelium (arrows). e and f show P-gp expression in peripheral tissue where arrows indicate alveolar macrophages and arrow heads denotes alveolar epithelial cells. g show P-gp expression in alveolar type II cells (TTF1 positive) after co-staining with P-gp (green) and TTF1 (red) antibodies (arrow heads). Scale bar: 20 μm
