ltured retinal microglia activated by lipopolysaccharide (LPS) have been used to study microglial behavior as an in vitro model of neuroinflammation.9 Studies have shown that following neuroinflammation through brain injury, activated microglia release proinflammatory cytokines such as TNF-?? which instigates a cascade of inflammation and neurodegeneration.10 We hypothesize that activated microgli
