| Research Abstract |
We have tried to make in vivo gene therapy vectors targeting dorsal root ganglia (DRG) by using 3 kinds of 7 amino acids sequence that could specifically bind to DRG neurons (DRG1, DRG2, DRG3). Phage vector system was obtained by transformations of the isolated 3 kinds of peptites to the PIII of the M13 phage. The test vectors were made by an introduction of green fluorescent protein (GFP) to multi-cloning site of the vector to see the effect of the gene expression. The vectors were administrated to subarachnoid space of mice, and the GFP-expression was examined in DRG tissues. Compared with the results of a study using GST-fusion protein, the expression of GFP by a gene transfer was very low by phage vector system. This might be caused by the unstableness of the phage itself, and we need a further arrangement for the improvement of the expression efficiency.
