Understanding how astrocytes interact with the blood-brain barrier in stroke conditions
Official title: Deciphering Mechanisms of Astrocyte-BBB Interaction in Normal and Ischemic Stroke
Funded at Baylor College of Medicine · NIH-11057550 · Data updated 2026-11-12
This study is looking at how certain brain cells help keep the blood-brain barrier healthy, especially during and after a stroke, to find new ways to protect the brain and improve recovery.

Who could benefit from this research
✓Could help
Ideal candidates for this research are adults who have experienced an ischemic stroke or are at risk for such events.
✕Less likely to help
Patients with non-ischemic strokes or other unrelated neurological conditions may not benefit from this research.
What this research studies
This research investigates the role of astrocytes, a type of brain cell, in maintaining the blood-brain barrier (BBB), which is crucial for brain health. The study aims to uncover how these cells interact with blood vessels, especially during and after ischemic stroke, a condition where blood flow to the brain is disrupted. By using genetically modified mice, researchers will explore the mechanisms that lead to BBB dysfunction and identify potential targets for treatment. This could help in developing therapies to protect the brain after a stroke.
Why it matters
Potential benefit: If successful, this research could lead to new treatments that improve recovery and outcomes for stroke patients by protecting the blood-brain barrier.
How similar studies have gone: Previous research has shown promising results in understanding astrocyte functions in other neurological conditions, suggesting that this approach may yield valuable insights.
