Who could benefit from this research
✓Could help
Adults with Down syndrome who have undergone clinical characterization and have brain tissue samples available for research.
✕Less likely to help
Most participants will contribute tissue data; direct benefits to individuals are not guaranteed.
What this research studies
This project focuses on aging adults with Down syndrome who are at risk for Alzheimer’s-type brain changes. Researchers will use spatial multi-omics to map transcripts, epigenetic marks, and proteins in hundreds of brain samples, aiming to understand why some individuals decline earlier while others show resilience. By examining neuroinflammation, white matter changes, and synaptic function, the study seeks to reveal molecular pathways involved in disease progression. The results will create a rich dataset to speed translational research and identify new targets for therapies. Participation will come from postmortem or brain tissue analyses complemented by clinically characterized samples.
Why it matters
Potential benefit: The findings could lead to new biomarkers and targets for therapies to delay or prevent dementia in people with Down syndrome.
How similar studies have gone: Previous studies show that brain-wide molecular mapping can identify disease pathways and potential targets in neurodegenerative conditions.
