Official title: Developing a PET tracer targeting myeloperoxidase activity for neurodegenerative diseases

Funded at Massachusetts General Hospital · NIH-11387774 · Data updated 2026-11-12

A new imaging tool is being developed to non-invasively show where inflammatory enzyme MPO is active in the brains of people with Alzheimer’s disease or related conditions.

Who could benefit from this research

Could help

Adults with or at risk for Alzheimer’s disease-related conditions who may undergo PET imaging as part of research.

Less likely to help

People without neuroinflammatory brain conditions or who cannot undergo PET imaging may not benefit.

What this research studies

This project creates a PET tracer that targets myeloperoxidase, an enzyme linked to brain inflammation in disorders like Alzheimer’s disease. By using this tracer, researchers hope to see early inflammatory signals in living patients and track how they change with disease progression or treatment. The study combines molecular design, preclinical testing, and early human-friendly imaging steps to ensure the tracer accurately reflects MPO activity in the brain. If successful, patients could benefit from earlier detection of neuroinflammation and more responsive monitoring for therapies.

Why it matters

Potential benefit: If successful, patients could benefit from earlier and more precise imaging of brain inflammation to guide treatment decisions.

How similar studies have gone: Prior work has shown MPO is linked to brain inflammation, supporting the potential value of MPO-targeted imaging, but this specific tracer approach is novel.
