| Outline of Final Research Achievements |
Retinal neuronal cell death underlies many incurable eye diseases such as retinitis pigmentosa and glaucoma. We demonstrated that branched chain amino acids (BCAAs) can increase ATP production by enhancing glycolysis and protect cells from cell death. Administration of BCAAs to mouse models of retinal degeneration, rd10 mice, significantly attenuated photoreceptor cell death both morphologically and functionally. Administration of BCAAs to mouse models of glaucoma, GLAST K/O mice, also significantly attenuated retinal ganglion cell death. These results suggest that administration of BCAAs could contribute to a comprehensive therapeutic strategy for retinal neurodegenerative diseases such as retinitis pigmentosa and glaucoma.
