Outline of Final Research Achievements

The aim of this study is to rescue the retina from the oxidative stress by using microbial ion channels. We develop the plasmid vectors including various types of microbial ion channel genes and established the constitutively those gene-expressing cell lines. We tested the protective effect on the glutamate toxicity in those cells. We could observe the protective effect in constitutively expressed cation channel gene but not chloride channel genes in the cells.
