What this research studies

This project focuses on extracellular vesicles (EVs), tiny particles released by brain cells that can cross into the bloodstream, to learn about normal brain function and disease such as schizophrenia. Researchers will isolate EVs from blood samples and analyze their RNA and protein cargo to find molecular signals linked to brain processes. They will compare these signals to known brain findings and to available tissue donor information to identify markers that reflect what's happening in the brain. The aim is to develop non-invasive blood-based biomarkers that could improve diagnosis, prognosis, or treatment monitoring.

Who could benefit from this research

Good fit: Ideal candidates are people with schizophrenia and matched healthy volunteers who can provide blood samples and, where requested, consent to tissue donation.

Not a fit: People who do not have brain disorders or who are unable or unwilling to provide blood samples or tissue donation are unlikely to benefit directly from participating.

Why it matters

Potential benefit: If successful, this work could enable blood tests to help diagnose or monitor schizophrenia and other brain conditions.

How similar studies have performed: Early studies using brain-derived EVs show promising biomarker signals, but directly linking EV RNA cargo to brain disease processes in schizophrenia remains largely novel and exploratory.
