| Research Abstract |
Hepatic ischemiaereperfusion (I/R) leads to activation of Kupffer cells (KCs). We have evaluate the interaction between platelets and KCs in the hepatic microcirculation after I/R. In the I/R group, the number of adherent platelets increased significantly after I/R. More than 50% of the adherent platelets adhered to KCs. We succeeded in visualizing the dynamics of both KCs and platelets in the hepatic sinusoids. Liver ischemia induced the adhesion of platelets to KCs in the early period, which could play a key role in reperfusion injury of the liver.
