Parkinson's disease, multiple system atrophy and dementia with Lewy bodies are brain diseases that share one culprit. In each, the protein alpha-synuclein misfolds and clumps together.

What they work on

  1. Detect and amplify small amounts of alpha-synuclein strains from body fluids and brain tissue of patients with Parkinson's disease, multiple system atrophy and dementia with Lewy bodies, using the seeding-based PMCA (RT-QuIC) assay.
  2. Test whether different synucleinopathies carry distinct alpha-synuclein conformational strains or sub-strains, by comparing amplified products with biochemical, structural and biological techniques.
  3. Relate the structural features of amplified alpha-synuclein strains to their disease-causing behavior, laying groundwork for a biochemical test that tells synucleinopathies apart.

More about the research

Together they are called synucleinopathies. Yet the diseases look different in the clinic, progress differently and need different treatments. They are hard to tell apart early, especially Parkinson's versus multiple system atrophy, and they are often diagnosed only after brain damage has begun. This project asks whether each disease carries its own structural "strain" of misfolded alpha-synuclein that could be detected and told apart.

Why it matters

Patients with Parkinson's disease, multiple system atrophy and dementia with Lewy bodies are often hard to diagnose early and accurately, even though their outlook and treatment differ. A test that identifies disease-specific alpha-synuclein strains in body fluids could improve differential diagnosis, help sort patients into the right groups, guide enrollment in clinical trials and support personalized treatment.
