| Outline of Final Research Achievements |
In this study, we identified that the type and expression levels of immune molecules expressed in tumor infiltrating immune cells are different in each hepatocellular carcinoma (HCC) patient. We also identified that the differences are deeply associated with the etiology of HCC and the expression levels of many immune molecules in non-alcoholic steatohepatitis (NASH)-related HCC patients are lower than those in hepatitis B or C-related HCC patients. In addition, immune cell profiles are also different in the 3 groups. The frequency of tumor-associated antigen-specific T cells is lower in NASH-related HCC patients compared with that of other 2 groups and it is correlated with the specific immune cell profiles.
