Neurons are particularly dependent on robust quality control pathways to maintain cellular homeostasis and functionality throughout their extended lifetime. Failure to regulate protein and organelle integrity is linked to devastating neurodegenerative diseases. Autophagy is a lysosomal degradation pathway that maintains homeostasis by recycling damaged or aged cellular components. Autophagy has important functions in development of the nervous system, as well as in neuronal function and survival. In fact, defects in autophagy underlie neurodegeneration in mice and humans. Here, we review the compartment-specific dynamics and functions for autophagy in neurons. Emerging evidence suggests novel pathways for the intercellular coordination of quality control pathways between neurons and glia to maintain homeostasis in the brain.
