| Outline of Final Research Achievements |
We analysed mainly the function of natural killer (NK) cells in the liver and blood of patients with hepatocellular carcinoma (HCC) before and after liver transplantation (LT), but any specific immune markers associated with the recurrence of HCC after LT could not be defined. However, we revealed that anti-NK cell activation ligand antibody and soluble immune checkpoint molecule were detected in the blood of patients with HCC. Our results may help unveiling the mechanisms responsible for tumor evasion of immune surveillance against HCC.
