Selective autophagy: The new player in the fight against neurodegenerative diseases?

Autophagy is the lysosome-mediated bulk degradation of cellular components for material recycling to maintain cellular homeostasis. Autophagy was initially regarded as a nonselective process, however, recent evidence indicates that this process can in fact be highly selective, especially for targeting and degrading organelles, invading pathogens and protein aggregates. Recent studies have revealed an intrinsic connection between selective autophagy and neurodegenerative diseases, including Alzheimer's disease and Parkinson's disease. Given the vital roles of selective autophagy in these neurodegenerative diseases, modulation of this process is emerging as a new therapeutic strategy for neuroprotection. This review introduces the concept of selective autophagy, provides an overview of the pathological connection between selective autophagy and neurodegenerative diseases, and discusses approaches to modulate selective autophagy for therapeutic effects against neurodegenerative diseases.
