Descripción
The aim of the present report was to analyze the involvement of glutamate neurotoxicity in retinal ganglion cell loss and optic nerve damage induced by experimental optic neuritis. For this purpose, the authors used an optic neuritis model induced by immunisation with myelin oligodendrocyte glycoprotein (AON). The authors describe a correlation in the timing of retinal ganglion cell (RGC) loss with alterations in the optic nerve actin cytoskeleton dynamic, and visual dysfunction. In addition, they show that an intravitreal injection of glutamate mimics, and an NMDA receptor antagonist avoids the effect of pre-clinical AON on visual functions and RGC number, as well as on optic nerve actin cytoskeleton. Taken together, their results support that avoiding glutamate neurotoxicity could become a new therapeutic approach for optic neuritis treatment.
