NIH-funded research R21 grant

Investigating how serotonin receptors affect the blood-brain barrier in Alzheimer's disease.

Official title: 5HT3 receptors and blood-brain barrier dysfunction in ADRD

Funded at Augusta University · NIH-11253669 · Data updated 2026-11-12

This study is looking at how certain receptors in the brain might affect the protective barrier that keeps harmful substances out, which could help us understand and find new ways to treat Alzheimer's disease and related conditions.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals diagnosed with Alzheimer's disease or related disorders characterized by blood-brain barrier dysfunction.

Less likely to help

Patients with conditions unrelated to Alzheimer's disease or those without blood-brain barrier dysfunction may not benefit from this research.

What this research studies

This research focuses on understanding the role of serotonin subtype 3 receptors (5HT3R) in the dysfunction of the blood-brain barrier (BBB) associated with Alzheimer's disease and cerebral amyloid angiopathy. The study aims to explore how changes in these receptors can lead to increased permeability of the BBB, which may contribute to inflammation and neuronal damage. By examining postmortem human brain tissues and mouse models, the researchers hope to identify mechanisms that disrupt the BBB and develop potential therapeutic targets to restore its function.

Why it matters

Potential benefit: If successful, this research could lead to new treatments that improve blood-brain barrier integrity and potentially slow the progression of Alzheimer's disease.

How similar studies have gone: Previous research has shown promising results in understanding blood-brain barrier dysfunction in Alzheimer's disease, indicating that this approach may yield valuable insights.
