How platelets affect brain injury after a stroke

Official title: Platelet-Mediated Neutrophil Extracellular Traps Regulate Ischemic Stroke Injury

Funded at Washington University · NIH-11169374 · Data updated 2026-11-12

This study is looking at how certain blood cells, called platelets and neutrophils, can cause damage during strokes when blood flow to the brain is blocked, and it aims to find new ways to help stroke patients recover better by testing a new treatment that stops a harmful process these cells create.

Who could benefit from this research

Could help

Ideal candidates for this research are individuals who have experienced an ischemic stroke and are seeking new treatment options.

Less likely to help

Patients who have not had a stroke or those with hemorrhagic strokes may not benefit from this research.

What this research studies

This research investigates the role of platelets and neutrophils in causing damage during ischemic strokes, which occur when blood flow to the brain is blocked. The study aims to understand how these blood cells interact and contribute to stroke injury, particularly focusing on a process called neutrophil extracellular trap (NET) formation. By exploring the mechanisms behind NET release and its effects on stroke outcomes, the researchers hope to identify new therapeutic targets that could improve recovery for stroke patients. The approach includes laboratory experiments and animal models to test the effectiveness of a novel treatment that inhibits NET formation.

Why it matters

Potential benefit: If successful, this research could lead to new treatments that significantly improve recovery and outcomes for stroke patients.

How similar studies have gone: While the role of NETs in other conditions has been studied, this specific approach to targeting NET formation in ischemic stroke is novel and has not been extensively tested.
