Abstract
Optic nerve regeneration has been a challenge for many research groups around the world. It is used as a model to investigate regeneration of the central nervous system (CNS) and is also the subject of study that helps to understand many eyes’ diseases. In the last two decades, an important progress has been made in the optic nerve regeneration field. Lessons from both cellular and molecular levels have taught researchers important mechanisms involved in the failure of nerve fiber regeneration and also retinal ganglion cells (RGCs) death after an injury. These two events are crucial and lead people to blindness, because RGCs are the projecting neurons from the retina which send visual information to the brain. When stimulated, some signaling pathways have already been described as neuroprotective and proregenerative of the optic nerve, although some studies have demonstrated that these two effects can happen by activation of distinct signaling pathways. The goal in the field of optic nerve regeneration is an effective therapy that can promote great levels of RGCs survival and optic nerve regeneration. To reach this goal, researchers have combined different therapeutic strategies and have shown great levels of regeneration, with some studies showing that optic nerve fibers can reenter the brain in sufficient numbers to cause partial recovery of vision.
