PET imaging of the GluN2B brain receptor linked to Alzheimer's

Translation of GluN2B-selective PET radiopharmaceuticals in Alzheimers patients

NIH-funded research Emory University · NIH-11093378

This project uses a new PET tracer, [11C]Me-NB1, to help doctors see GluN2B receptor changes in the brains of people with Alzheimer's disease.

What this research studies

Researchers will translate a PET tracer called [11C]Me-NB1 that binds the GluN2B subunit of the NMDA receptor from preclinical models into people with Alzheimer's. Participants will have non-invasive PET scans along with cognitive and biomarker tests so researchers can compare GluN2B signals with clinical status and other markers. The work links findings from AD mouse models to human imaging to understand how GluN2B relates to synaptic dysfunction and disease progression. Overall, the approach aims to create a translatable imaging tool to support drug development and to monitor target engagement in therapeutic trials.

Who could benefit from this research

Good fit: Adults diagnosed with Alzheimer's disease or mild cognitive impairment due to Alzheimer's who can tolerate PET imaging and travel to the study site would be ideal candidates.

Not a fit: People without Alzheimer's disease, those with other types of dementia, pregnant individuals, or anyone unable to undergo PET scans would not be expected to benefit from participation.

Why it matters

Potential benefit: If successful, this could give clinicians a way to track a synaptic receptor tied to memory loss and help show whether new Alzheimer drugs reach their intended target.

How similar studies have performed: PET imaging of amyloid and tau in Alzheimer's has been successful, but GluN2B-selective PET tracers are a newer approach that is only recently being translated to humans.
