OCTN2 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-OCTN2 antibody (brown) and counterstained with hematoxylin (blue). a and b Show expression of OCTN2 on the apical side of bronchial epithelium (arrow heads). c and d Show OCTN2 expression in bronchiolar epithelial cells (arrow heads). e and f Show positive staining of OCTN2 in alveolar macrophages (arrows) and in alveolar epithelial cells (arrow heads). g Confirms the OCTN2 expression in alveolar type II cells (TTF1 positive) (arrows) after co-staining with OCTN2 (green) and TTF1 (red) antibodies. Scale bar: 20μm
