WebJul 22, 2024 · Using an antibody marker of CaMKII activity, Chen’s team discovered that CaMKII pathway signaling was compromised whenever retinal ganglion cells were exposed to toxins or trauma from a crush injury to the optic nerve, suggesting a correlation between CaMKII activity and retinal ganglion cell survival. WebJan 5, 2024 · Rodent models of optic nerve crush have often been used to study rapid degeneration of RGCs, as well as their axon regeneration. Crush may not be a “true” model of glaucoma, but it is an optic neuropathy leading to RGC death and offers the advantage of investigation of rapid RGC loss and its underlying mechanisms within a short time.

WebThe optic nerve crush injury is a well-accepted model to study the mechanisms of axonal regeneration after trauma in the CNS. The infection of retinal ganglion cells (RGCs) with an adeno-associated virus serotype 2 - ciliary neurotrophic factor (AAV2.CNTF) was previously shown to stimulate axonal regeneration. WebWe agree that this would maximize the impact of the paper and tested it accordingly. To benchmark the software’s performance in remyelinating tissues, we chose an optic nerve crush model and incorporated the results in Figure 3D-F. We find that the software can accurately measure the thin myelin sheaths in the remyelinating optic nerve.
