Monitoring α-synuclein aggregation

Area of Science:

• Neuroscience
• Biochemistry
• Pathology

Background:

• Synucleinopathies, such as Parkinson's disease (PD), dementia with Lewy Bodies (DLB), and multiple system atrophy (MSA), are linked to alpha-synuclein (α-syn) misfolding and aggregation.
• Aggregated α-syn forms cytoplasmic inclusions in affected brain cells, a hallmark identified in 1997.
• Research on "synuclein aggregation" has surged, with over 6000 publications since 1997.

Purpose of the Study:

• To review essential techniques for studying α-syn aggregation.
• To clarify the information provided by different methods and their applications.
• To critically assess the relevance and limitations of current tools in understanding synucleinopathies.

Main Methods:

• Review of established and emerging techniques for observing and quantifying α-syn aggregation.
• Analysis of methods applicable to in vitro, in vivo, and post-mortem samples.
• Emphasis on recent breakthroughs in understanding α-syn structure and dynamics.

Main Results:

• Significant progress has been made in understanding α-syn aggregation mechanisms and identifying diverse polymorphs.
• Various techniques provide insights into α-syn structure, dynamics, and aggregation states.
• The review highlights the importance of method selection and interpretation for accurate assessment.

Conclusions:

• Understanding the tools and their limitations is vital for advancing synucleinopathy research.
• Recent advancements offer new perspectives on α-syn structure and dynamics.
• This review provides a framework for researchers to effectively study α-syn aggregation and its role in disease.
