| Research Abstract |
We determined neuroprotective properties of systemic statin using optic nerve crush model of rats. There was an accumulation of CD68-positive cells at the crushed site, and the immunoreactivity to MCP-1 was intensified around the lesion. There was an increase in the mRNA levels of the CD68, MCP-1, TNF-α, etc. Systemic statin significantly depressed these inflammatory changes, and rescued the retinal ganglion cells (RGCs) after the injury. Statin significantly reduced the NF-κB activation in cultured astrocytes. Thus, simvastatin may have protective roles on the RGCs possibly through suppression of astroglial NF-κB activation.
