Expression of A2AR in small and large pulmonary arteries in WT and A2AR KO mice by fluorescence immunohistochemistry. A2AR immunoreactivity was determined in lung sections for WT and A2AR KO mice by fluorescence immunohistochemistry as described in Materials and Methods. Lung sections were co-stained with DAPI for total cells. a–d A2AR-positive cells in lung sections. a1–d1 Nucleoli stained by DAPI. White arrow = pulmonary artery; red arrow = A2AR-positive cells in pulmonary artery; blue arrow = A2AR-positive cells in not pulmonary artery. ×200.
