BACKGROUND Adenosine provides renovascular protection in mouse models of ischemia-reperfusion injury (I/RI) through purinergic members of the G protein-coupled receptor family, such as the adenosine 2A receptor (A2AR). Ectonucleotidases CD39 and CD73 are integral vascular and immune nucleotidases that regulate extracellular adenosine signaling. Current(More)
BACKGROUND Adenosine agonists are protective in numerous models of ischemia-reperfusion injury (IRI). Pericellular adenosine is generated by the hydrolysis of extracellular adenosine triphosphate and adenosine diphosphate by the ectonucleotidase CD39 and the subsequent hydrolysis of adenosine monophosphate (AMP) by the ectonucleotidase CD73. CD39 activity(More)
Hypoxic injury occurs when the blood supply to an organ is interrupted; subsequent reperfusion halts ongoing ischemic damage but paradoxically leads to further inflammation. Together this is termed ischemia–reperfusion injury (IRI). IRI is inherent to organ transplantation and impacts both the short- and long-term outcomes of the transplanted organ.(More)
