Understanding Brain Changes in Opioid Relapse

Integrative single-cell spatial transcriptomic, anatomical, and functional profiling of brain-wide ensembles engaged by opioid relapse

NIH-funded research University of Washington · NIH-11124230

This project aims to understand how fentanyl changes the brain to cause addiction and relapse, helping us find new ways to prevent and treat opioid abuse.

What this research studies

Opioid abuse, especially with fentanyl, causes immense suffering and many deaths. We don't fully understand why some people become addicted and relapse. This project uses advanced brain mapping techniques in mice to look closely at how fentanyl changes brain cells and circuits. By studying these changes, we hope to uncover the specific brain mechanisms that lead to addiction and relapse.

Who could benefit from this research

Good fit: This foundational research is for anyone affected by opioid addiction, as it seeks to uncover the basic brain mechanisms underlying the condition.

Not a fit: Patients seeking immediate clinical treatment or direct participation in a human trial would not directly benefit from this basic science project.

Why it matters

Potential benefit: If successful, this work could lead to new treatments or prevention strategies for opioid addiction and relapse by targeting specific brain pathways.

How similar studies have performed: This project uses newly developed, advanced technologies for brain mapping, making its approach novel and highly detailed compared to previous methods.
