Outline of Final Research Achievements |
AAPH administration was an effective model of oxidative stress-induced glaucoma, showing that oxidative stress directly activated the calpain pathway and induced RGC death in mice retina. Furthermore, inhibition of the calpain pathway protected the RGCs after AAPH administration. In our study, suppressing calpain activation reduced RGC death, suggesting that it may be a good candidate for neuroprotection therapy.
