Early genes in optic neurodegeneration
WebImmediate early gene. Immediate early genes ( IEGs) are genes which are activated transiently and rapidly in response to a wide variety of cellular stimuli. They represent a … WebHere, we review the mechanisms involved in glaucomatous neurodegeneration and regeneration in the central nervous system. Then, we point out current limitations of gene therapy platforms and review a myriad of studies that use viral vectors to manipulate genes in retinal ganglion cells, as a strategy to promote neuroprotection and regeneration.
