Targeting α-Synuclein: Current Strategies and Emerging Therapies for Synucleinopathies

Area of Science:

• Neuroscience
• Molecular Biology
• Pathology

Background:

• Alpha-synuclein (α-syn) is central to Parkinson's Disease (PD) and synucleinopathies.
• Maintaining α-syn protein homeostasis involves autophagy, chaperone, and proteolysis pathways.
• Dysfunction in these pathways leads to α-syn accumulation, neuroinflammation, and neurodegeneration.

Purpose of the Study:

• To review the role of α-syn in neurodegenerative diseases.
• To explore current and emerging therapeutic strategies for α-syn related disorders.
• To highlight challenges and future directions in treating synucleinopathies.

Main Methods:

• Literature review of α-synuclein biology and pathology.
• Analysis of cellular pathways involved in α-syn homeostasis.
• Survey of therapeutic interventions targeting α-syn.

Main Results:

• Autophagy dysfunction and oxidative stress exacerbate α-syn misfolding, aggregation, and neurodegeneration.
• Therapeutic approaches include immunization, aggregation inhibitors, gene silencing, and drug delivery.
• Novel strategies involve herbal formulations and enhancing protein quality control.

Conclusions:

• Understanding α-syn biology is crucial for developing effective treatments for PD and related disorders.
• Early and multi-targeted interventions are urgently needed.
• Overcoming challenges in clinical trials (target identification, biomarkers, patient stratification) is key for therapeutic success.
