|
• at 6 months of age, the optic nerve shows a significant reduction in aquaporin 4 (AQP4) expression with no significant change in GFAP expression

|
|
• as loss of AQP4 and microglial activation in the optic nerve precedes RGC loss and accumulation of Abeta aggregates in the retina, the cause of neuronal loss appears to be optic nerve degeneration
