MATE1 protein expression in airway epithelial cells, alveolar macrophages and infiltrating T-cells. Paraffin sections of human lung tissue from healthy individuals (left column) and ex-smokers with COPD (right column) were immunostained with anti-MATE1 antibody (brown) and counterstained with hematoxylin (blue). a and b Show apical staining in bronchial epithelial cells and in c and d bronchiolar epithelium (arrow heads) as well as staining in some inflammatory cells migrating through the bronchial and bronchiolar epithelium (arrows). e and f Show strong expression of MATE1 in alveolar macrophages in the peripheral tissue (arrows). g and h Show co-staining of MATE1 antibody with T cell (CD3) and B cell (CD20) marker antibodies demonstrating that the infiltrating T cells (arrows) but not B cells are MATE1 positive. Scale bar: 20 μm
