Copper Overload Affects α‐Synuclein Clearance Mechanisms in a Parkinson's Disease In Vitro Model (Advanced Biology 5/2026)

Key Points

• Investigating how copper overload affects clearance mechanisms of α-synuclein in Parkinson's Disease.
• Used a cellular model of Parkinson's Disease to assess copper's effects.
• Examined autophagic flux and ubiquitin-proteasome system activity.
• Evaluated the accumulation of phosphorylated α-synuclein.
• Copper overload significantly impaired both autophagic flux (exact metrics not provided) and ubiquitin-proteasome system activity.
• Resulted in increased neuritic accumulation of phosphorylated α-synuclein.
• Highlighted metal dyshomeostasis's role in α-synuclein pathology.
