Abstract Background Lung ischemia-reperfusion IR injury leads to significant morbidity and mortality which remains a major obstacle after lung transplantation. However the role of various subset s of lung cell populations in the pathogenesis of lung IR injury and the mechanisms of cellular protection remain to be elucidated. In the present study we investigated the effects of adenosine A2A receptor A2AAR activation on resident lung cells after IR injury using an isolated buffer-perfused murine lung model. Methods To assess the protective effects of A2AAR activation three groups of C57BL 6J mice were studied a sham group perfused for 2 hr with no ischemia an IR group 1 hr ischemia 1 hr reperfusion and an IR ATL313 group where ATL313 a specific A2AAR agonist was included in the reperfusion buffer after ischemia. Lung injury parameters and pulmonary function studies were also performed after IR injury in .
