Understanding blood vessel changes in Alzheimer’s

Elucidating the Role of Endothelial Dysfunction in Alzheimer Disease: Towards A New Data-Driven Disease Model

NIH-funded research Saint Louis University · NIH-11328208

This project looks for proteins and RNA signs of blood-vessel damage in people with Alzheimer’s to see how those changes relate to memory and brain scans.

What this research studies

If you join, researchers will measure specific proteins in cerebrospinal fluid and RNA in brain tissue using proteomics and transcriptomics across three large long-term groups (over 3,400 people) including late-onset Alzheimer’s, healthy volunteers, and other dementias. They will compare these endothelial biomarkers to years of cognitive tests and MRI scans to see whether blood-vessel changes appear early in the disease. The team will build a data-driven model to map how endothelial dysfunction may fit into Alzheimer’s progression. Much of the work uses stored samples and long-term clinical data to link these markers to real-world memory and scan outcomes.

Who could benefit from this research

Good fit: Ideal candidates are people enrolled in the participating long-term cohorts, including those with late-onset sporadic Alzheimer’s, healthy controls, or non-Alzheimer dementias who can provide clinical data and biological samples.

Not a fit: People without relevant clinical enrollment or who cannot provide CSF or include brain tissue samples may not see direct benefit from this specific project.

Why it matters

Potential benefit: If successful, this work could help detect Alzheimer’s earlier and point to new ways to protect the brain’s blood vessels to slow disease.

How similar studies have performed: Using CSF proteomics and brain transcriptomics to study vascular changes in Alzheimer’s is relatively new and preliminary data are promising, but this is one of the first large longitudinal efforts focused on endothelial markers.
