Research Abstract

We have newly developed a light gated cation channel gene by the modification of channelrhodpsin gene derived from the clamydomonas. The modified channelrhodopsin has a sensitivity covered over a visible light. We could regain the visual function of blind patients by using the modified channelrhodopsin. Indeed, we could demonstrate the recovery of visual function in genetically blind rats by transucing the gene.
