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

Fig. 4

OCTN1 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-OCTN1 antibody (brown) and counterstained with hematoxylin (blue). a and b Show the OCTN1 expression on the apical side of the bronchial epithelium (arrow heads). c and d Show expression of OCTN1 in the bronchiolar epithelial cells (arrow heads). e and f The expression of OCTN1 in alveolar epithelial cells (arrow heads) and alveolar macrophages (arrows). g Shows the expression of OCTN1 in alveolar type II cells (TTF1 positive cells) after co-staining with OCTN1 (green) and TTF1 (red) antibodies. Scale bar: 20 µm
