Retinal Ganglion Cells In Neurodegeneration is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
This page provides comprehensive information about the cell type. See the content below for detailed information.
Retinal ganglion cells (RGCs) are the output neurons of the retina whose degeneration is a hallmark of glaucoma and occurs in various neurodegenerative diseases. The retina offers a unique window to study CNS neurodegeneration non-invasively.
