The Aim of this study is to analyze tumor-stromal interaction via C5a-C5aR axis in hepatocellular carcinoma (HCC).At first, we investigated whether human hepatic stellate cells (HSC) were in activated state or not in resected HCC specimen using confocal microscope. The result that αSMA staining, which is marker of activation in HSC, was detected in HSC around HCC lesions, meant that HSC was in activated state around human HCCs. In vitro, western blotting analysis revealed C5aR expression at HSC in a time dependent manner. Moreover, HSC increased αSMA expression by C5a stimulation. Therefore, HSC could be activated by C5a-C5aR axis. In addition, C5a stimulation increased HCC invasion and that was inhibited by C5aR-antagonist. From these results, C5a-C5aR could be a target therapy for HCC treatment.
