Retinal Ganglion Cells With Tauopathy is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Retinal ganglion cells (RGCs) develop tau pathology in Alzheimer's disease and other tauopathies, offering a unique window for non-invasive visualization of brain pathology through the eye.
