| Outline of Final Research Achievements |
Borna disease virus (BoDV) is an RNA virus persistently infecting stem cells. In this study, we aimed to construct a long-term stable gene transfer system that realizes stem cell therapy using the virus. The BoDV vector expressing IL2RG, which is the causative gene of X-SCID, was prepared and inoculated into hematopoietic stem cells. This vector stably expressed the target gene, however, the transduction efficiency was low. The vector in which the G protein was replaced with CnBV-1 increased the efficiency by 15-fold as compared with BoDV. The improved vector significantly increased the efficiency of transduction into stem cells including iPS cells. BoDV vector with X/P gene of VSBV also increased the transduction efficiency. The improved BoDV vector prepared in this study could be a new platform for stem cell gene therapy.
