Investigating brain processes using tiny particles from blood

Studying normal and disease processes in brain with extracellular vesicles

NIH-funded research Virginia Commonwealth University · NIH-11038846

This study is looking at tiny particles in your blood that come from brain cells to find new ways to understand and diagnose brain disorders like mental health issues and substance use, all without needing to take samples directly from the brain.

What this research studies

This research focuses on understanding brain disorders, particularly psychiatric and substance use disorders, by studying extracellular vesicles (EVs) found in blood. EVs are small particles released by brain cells that carry important biological information, including RNA and proteins. By isolating these vesicles from blood samples, researchers aim to uncover non-invasive biomarkers that can provide insights into brain health and disease. This approach allows for the exploration of brain processes without needing direct access to brain tissue, which is often difficult to obtain from living patients.

Who could benefit from this research

Good fit: Ideal candidates for this research include individuals diagnosed with psychiatric or substance use disorders.

Not a fit: Patients with brain disorders that do not involve the study of extracellular vesicles may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved diagnosis and treatment options for patients with brain disorders.

How similar studies have performed: While the approach of using EVs to study brain processes is innovative, there have been preliminary studies suggesting the potential of EVs as biomarkers in other contexts.
