The aim of the present study was to investigate the potential role of adenosine A2A receptor (A2AR) activation in small‐for‐size liver transplantation. A rat orthotopic liver transplantation model was performed by using 40% (range: 36–46%) liver grafts. Recipients were given either saline (control group) or CGS 21680 (2‐p‐(2‐Carboxyethyl)phenethylamino‐5′‐N‐ethylcarboxamidoadenosine hydrochloride, a selective A2AR agonist), or CGS 21680+ ZM 241385 (a selective A2AR antagonist) immediately after reperfusion for 3 h. Compared with control group, CGS 21680 used at both low dose (0.05 μg/kg/min) and high dose (0.5 μg/kg/min) increased the survival rate from 16.7% (2/12) to 83.3% (10/12) and 66.7% (8/12), respectively. These effects correlated with improved liver function and preserved hepatic architecture. CGS 21680 effectively decreased neutrophil infiltration, suppressed pro‐inflammatory (TNF‐α, IL‐1β and IL‐6) expression, promoted expression of antiapoptotic molecules, and inhibited apoptosis. The effects of CGS 21680 were prevented when ZM 241385 was co‐administrated. In conclusion, the present study showed that A2AR activation alleviated portal hypertension, suppressed inflammatory response, reduced apoptosis, and potentiated the survival of small‐for‐size liver grafts. Our findings provide the rationale for a novel therapeutic approach using A2AR activation to maximize the availability of small‐for‐size liver grafts.
