Research Summary

Shin-ichiro  Fujii(M.D., Ph.D)

The aims of the laboratory are to extend basic studies for advancing immunotherapy and translational research, from basic studies back and forth to the bedside in the field of cancer and the control of other diseases. For this purpose, we have been focusing on projects related to a role of dendritic cells (DCs) in situ in tumor bearing animals. Additionally, we have been developing translational research projects to establish therapeutic strategies to generate strong antitumor immunity. We previously reported the full maturation of DCs soon after the activation of NKT cells in vivo. Based on this observation, we have developed and established artificial adjuvant vector cells (aAVC) as a new type of drug delivery system composed of NKT cell ligand and tumor-associated antigen. Our group has been making efforts in translational research toward eventual clinical trials. As the other translational research projects, we have been working a collaborative study of the RIKEN iPS-group and working on a joint clinical phase I /IIa study of NKT cell therapy.
