What this research studies

If you join, you'll be part of a multi-center effort (Penn, WUSTL, Pitt, UCSF, Yale) to create and test new PET tracers that bind to alpha-synuclein and 4R tau proteins in the brain. Chemists and structural biologists design candidate tracers and run lab and animal tests, then clinical teams use PET scans in people to see whether the tracers show the proteins reliably. Researchers will compare scans to clinical exams and biological samples to confirm the tracers' accuracy. Over time the team refines promising tracers for broader use in diagnosis and research.

Who could benefit from this research

Good fit: Ideal candidates include people with or suspected to have Alzheimer’s disease, Parkinson’s disease, progressive supranuclear palsy, frontotemporal degeneration, or other related dementia syndromes, plus healthy volunteers for comparison.

Not a fit: People whose cognitive or movement problems are known to be caused by non-proteinopathy conditions, or those seeking an immediate therapeutic benefit, are unlikely to gain direct clinical benefit from participating.

Why it matters

Potential benefit: If successful, these scans could help diagnose specific protein-related dementias earlier and more accurately and improve who is matched to the right clinical trials or treatments.

How similar studies have performed: PET tracers for amyloid and some forms of tau have been successful clinically, but reliable tracers for alpha-synuclein and specifically 4R tau are newer and still under development.
