| Outline of Final Research Achievements |
The aim of this study is to utilize the halorhodopsin (NpHR) gene derived from Halobacterium salinarum for producing OFF responses in the photoreceptor degenerated retina. We modified the amino acid sequence of NpHR (mNpHR) to express it into a mammalian cell. The mNpHR expression was clearly observed in the retina after the AAV2 mediated mNpHR gene transfer. However we could not get the expected responses such as the light induced OFF responses. We investigated the localization of mNpHR in the cell. The mNpHR expression was mainly observed in the endoplasmic reticurum but not in the cell membrane.
