Randomized trial shows deficient autophagy induces neurodegeneration in retinal ganglion cells, indicating the need for targeted interventions.

This research aims to clarify the role of autophagy in retinal ganglion cell function and its implications for neurodegeneration.
Utilized conditional knockout mice (Atg7 f/f and Atg5 f/f) to study autophagy deficiencies
Conducted immunostaining and transmission electron microscopy to analyze organelle accumulation
Performed mass spectrometry to identify protein accumulation related to damaged organelles
Deficient autophagy in RGCs led to significant loss of structural and functional integrity
Observations included increased accumulation of damaged organelles and heightened levels of p62 and LC3B
Mass spectrometry revealed a build-up of proteins linked to cellular component regulation and architecture

Sundaresan et al. (2026) studied this question.
