How abnormal alpha-synuclein shapes Lewy body and Alzheimer-related brain changes

Project II: Deciphering the Signatures of Pathological Changes on Alpha-Synuclein

NIH-funded research University of Pennsylvania · NIH-11184458

Researchers are comparing abnormal alpha-synuclein from different brain conditions to learn how it damages brain cells in people with Lewy body disorders and Alzheimer-related changes.

What this research studies

If you have a Lewy body disorder (like dementia with Lewy bodies, Parkinson’s disease with dementia, or multiple system atrophy) or Alzheimer-related brain changes, this team is studying the abnormal protein alpha-synuclein taken from human brains. They purify and amplify Lewy bodies from donated human brain tissue and use high-resolution structural, biochemical, and cell-biology methods to compare protein shapes across diseases. Lab cell models and molecular tests will show how different alpha-synuclein forms enter cells and disrupt the cell's waste-clearance (lysosome) systems. The goal is to connect specific protein shapes to the types of brain damage and symptoms people experience.

Who could benefit from this research

Good fit: Ideal candidates would include people with Lewy body disorders (DLB, PD/PDD, MSA), people with Alzheimer disease who have mixed pathology, and individuals who can consent to brain donation for research.

Not a fit: People without neurodegenerative disease or those seeking immediate clinical treatment are unlikely to receive direct benefit from this primarily lab-based research.

Why it matters

Potential benefit: If successful, this work could reveal disease-specific protein signatures that help diagnosis and point to new targets for treatments of Lewy body and Alzheimer-related dementias.

How similar studies have performed: Lab-made alpha-synuclein fibrils have been widely used to model disease but do not fully match human Lewy bodies, and amplifying human-derived Lewy bodies is a relatively new and promising approach.
