Expression of CD73 and the A_2BR in M2 macrophages.

<p>Lung sections from COPD or IPF patients were reacted with antibodies against CD73 (A, green) or the A_2BR (B, green) together with the M2 macrophage marker CD206 (red). In the merged images, yellow represents co-localization of CD73 or the A_2BR and the M2 marker, blue is dapi stained nuclei. Sections are representative of 10–14 different patients from each group. Scale bars = 100 µm.
