Development of vaccine technology using Sendai virus vector

New cancer therapy using genetically-engineered oncolytic Sendai virus vector.

We have developed a new type of Sendai virus-(SeV) based gene transfer vectors for cancer therapy. The matrix gene-, indispensable for particle formation, deficient and fusion gene-, essential for cell-fusion and deciding viral tropism, redesigned SeV vector loses vector particle formation from transduced cells and gains cell-to-cell spreading in protease-dependent, namely controllable, manner....

Hepatitis C Virus and Vaccine Development

The prevalence of Hepatitis C virus (HCV) is approximately 3% around the world. This virus causes chronic hepatitis, liver cirrhosis and hepatocellular carcinoma. The effectiveness of interferon-α and ribavirin therapy is about 50% and is associated with significant toxicity and cost. Hence, generating new vaccines or drugs is an obligation. However, there is no vaccine available for clinical u...

Development of an Attenuated Live Virus Vaccine against Sheep Pox

Generation of Induced Pluripotent Stem Cells from Human Nasal Epithelial Cells Using a Sendai Virus Vector

The generation of induced pluripotent stem cells (iPSCs) by introducing reprogramming factors into somatic cells is a promising method for stem cell therapy in regenerative medicine. Therefore, it is desirable to develop a minimally invasive simple method to create iPSCs. In this study, we generated human nasal epithelial cells (HNECs)-derived iPSCs by gene transduction with Sendai virus (SeV) ...

A Sendai virus-derived RNA agonist of RIG-I as a virus vaccine adjuvant.

The innate immune system is responsible for recognizing invading pathogens and initiating a protective response. In particular, the retinoic acid-inducible gene 1 protein (RIG-I) participates in the recognition of single- and double-stranded RNA viruses. RIG-I activation leads to the production of an appropriate cytokine and chemokine cocktail that stimulates an antiviral state and drives the a...
