The final, formatted version of the article will be published soon.

Neurodegenerative proteinopathies are characterised by impaired protein clearance and the accumulation of misfolded or aggregated proteins, ultimately leading to neuronal death. The two principal pathways responsible for protein degradation in cells are the ubiquitin proteasome system (UPS) and autophagy. Emerging evidence indicates that these pathways share regulatory components and engage in extensive crosstalk. In this review, we summarise the mechanisms of the UPS and autophagy, highlight their points of interaction, and discuss therapeutic opportunities to modulate both systems in parallel to enhance protein clearance in neurodegenerative disease.
