What this research studies

Researchers will identify genes in brain endothelial cells that control the production and breakdown of dopamine and serotonin at the blood–brain barrier. They will manipulate those genes in laboratory cell and animal models and analyze tissue and dataset evidence to see how changes affect barrier function and nearby neural circuits. The team aims to connect endothelial monoamine handling with features seen in Alzheimer's disease, such as blood–brain barrier disruption and altered brain signaling. Findings could point to new ways to protect the barrier or adjust brain chemistry.

Who could benefit from this research

Good fit: People with Alzheimer's disease or mild cognitive impairment, or those willing to provide biological samples for research, would be the most relevant candidates to engage with this work.

Not a fit: People without neurodegenerative conditions or those seeking immediate clinical treatment are unlikely to receive direct benefit from this basic laboratory-focused project.

Why it matters

Potential benefit: If successful, this work could reveal new targets to protect the blood–brain barrier or alter brain chemistry in ways that slow or reduce Alzheimer's-related decline.

How similar studies have performed: Prior work has linked blood–brain barrier breakdown and monoamine changes to Alzheimer's, but studying endothelial metabolism of these neurotransmitters is relatively new and mostly tested in lab models.
