Objective To summarize the function of Kupffer cell for the ischemia reperfusion injury after liver’s transplatation. Methods The literatures which about the function of Kupffer cell for the ischemia reperfusion injury after liver’s transplatation were reviewed. Results Kupffer cells are the resident macrophages of the liver, which can be activated to generate a range of inflammatory mediators, including cytokines, reactive oxygen intermediates, chemokines, and other factors to startup the ischemia reperfusion injury （IRI）, and to cause the liver graft dysfunction. On the other hand, Kupffer cells can protect the ischemia reperfusion injury by release NO and HO-1. The CO, which is the byproduct of heme degradation by the heme oxygenases （HO-1），has the same function for IRI. Conclusions The Kupffer cells have bidirectional function for the ischemia reperfusion injury of liver’s transpatation. Thus, how to decrease the harmful factors and up-regulate the beneficial substances by Kupffer cells will be the key points in preventing IRI after liver transplantation in future.
