Now much attention has been focused on gene therapy and nucleic acid therapeutics as a novel class of therapeutic modality. We are conducting research on the development of next-generation gene therapy products and nucleic acid therapeutics.

Research theme

Cancer Therapy using Oncolytic Viruses

Oncolytic viruses, which specifically infect and kill cancer cells, have gained much attention as a novel anticancer agent. Now, research about oncolytic adenovirus and reovirus is ongoing.

Gene Therapy using Recombinant Virus Vectors

Efficient and safe delivery of therapeutic genes into target cells is crucial for successful gene therapy. Now we are doing several projects about development and evaluation of novel virus-based gene delivery vehicles.

Research about Oligonucleotide Therapeutics

Nucleic acid therapeutics are a novel category of therapeutics for treatment of intractable diseases. Now our research is focusing on double stranded RNA-induced cellular events.
