Abstract Background Neutrophil adhesion and migration are critical in hepatic ischemia and reperfusion injury I R . P-selectin and the intercellular adhesion molecule ICAM -1 can mediate neutrophil-endothelial cell interactions neutrophil migration and the interactions of neutrophils with hepatocytes in the liver. Despite very strong preclinical data recent clinical trials failed to show a protective effect of anti-adhesion therapy in reperfusion injury indicating that the length of injury might be a critical factor in neutrophil infiltration. Therefore the aim of this study was to assess the role of P-selectin and ICAM-1 in neutrophil infiltration and liver injury during early and late phases of liver I R. Methods Adult male wild-type and P-selectin ICAM-1-deficient P I null mice underwent 90 minutes of partial liver ischemia followed by various periods of reperfusion 6 15 h and a survival study . Liver injury was assessed by plasma level of alanine aminotransferase .
