Protection from pulmonary ischemia-reperfusion injury by adenosine A2A receptor activation

摘要

BackgroundLung 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.
