Abstract:
Autophagy is a cellular process that degrades intracellular components, including misfolded proteins and damaged organelles. Many neurodegenerative diseases are considered to progress via the accumulation of misfolded proteins and damaged organelles; therefore, autophagy functions in regulating disease severity. There are at least two types of autophagy (canonical autophagy and alternative autophagy), and canonical autophagy has been applied to therapeutic strategies against various types of neurodegenerative diseases. In contrast, the role of alternative autophagy has not yet been clarified, but it is speculated to be involved in the pathogenesis of various neurodegenerative diseases, including Alzheimer's disease.
Insights
Autophagy degrades cellular waste, impacting neurodegenerative disease severity. Canonical autophagy is a therapeutic target, while alternative autophagy
Area of Science:
- Cellular Biology
- Neuroscience
Background:
- Autophagy is a key cellular process for degrading misfolded proteins and damaged organelles.

Purpose of the Study:
- To explore the role of autophagy in neurodegenerative diseases.
- To differentiate the functions of canonical and alternative autophagy.
- To investigate the potential of autophagy modulation as a therapeutic strategy.
Main Methods:
- Literature review on autophagy mechanisms.
- Analysis of studies investigating canonical autophagy in neurodegenerative disease models.
- Review of emerging research on alternative autophagy pathways.
Main Results:
- Canonical autophagy has been successfully targeted in therapeutic strategies for neurodegenerative diseases.
