How astrocyte STAT3 affects blood vessel and barrier problems in Alzheimer's
STAT3 activation in astrocytes as a driver of neurovascular dysfunction in Alzheimer's disease and related dementias
['FUNDING_R01'] · VANDERBILT UNIVERSITY · NIH-10795752
This project looks at whether a protein called STAT3 in star-shaped brain cells (astrocytes) causes blood‑brain barrier and blood‑vessel problems that worsen Alzheimer's and related dementias.

What this research studies
Researchers will examine brain samples from people who had Alzheimer's to see if astrocytes with active STAT3 sit near inflamed blood vessels. They will use human cell models that grow astrocytes together with brain endothelial cells to mimic the blood‑brain barrier and watch how inflammatory signals change barrier function. The team will compare different molecular states of reactive astrocytes to understand which ones harm or help blood vessels. Ultimately they will test whether blocking STAT3 activity can protect the barrier in these models.
Who could benefit from this research
Good fit: People diagnosed with Alzheimer's disease or related dementias, or families willing to donate postmortem brain tissue, would be most relevant to this work.
Not a fit: People without neurodegenerative disease or those seeking an immediate treatment are unlikely to receive direct or immediate benefit from this project.
Why it matters
Potential benefit: If successful, this work could point to new ways to protect the blood‑brain barrier and slow vascular damage that contributes to cognitive decline in Alzheimer's.
How similar studies have performed: Previous studies have shown mixed results—reactive astrocytes can both harm and help blood‑brain barrier function—while preliminary human tissue data suggest increased STAT3‑activated astrocytes in Alzheimer's, so this builds on emerging but not yet settled evidence.
