Self-introduction
I am researching cancer immunity and transplantation immunity in hepatobiliary, pancreatic and transplantation fields. Specifically, I am investigating the mechanism of hepatocellular carcinoma recurrence and the development of therapeutic strategies. I am also engaged in research on regenerative medicine, which is cell therapy after liver surgery and liver transplantation.
