Understanding Brain Changes in Opioid Dependence

Circuitry dynamics underlying opioid-dependence: Integrating structural, functional, and transcriptomic mechanisms

['FUNDING_R01'] · UNIVERSITY OF PENNSYLVANIA · NIH-11174270

This project aims to understand how brain connections and activities change with long-term opioid use, which could help us learn more about addiction, withdrawal, and relapse.

What this research studies

When someone uses opioids for a long time, their brain changes in ways that contribute to addiction, withdrawal, and the risk of relapse. We don't fully understand how these brain networks, which contain opioid receptors, adapt over time. This work will map the specific types of cells, their genetic activity, and how their connections shift in key brain areas during opioid use and withdrawal. By doing this, we hope to uncover the detailed brain changes that lead to and maintain opioid dependence.

Who could benefit from this research

Good fit: This foundational work does not directly involve patient participation but seeks to understand the underlying brain mechanisms of opioid dependence.

Not a fit: Patients not experiencing opioid dependence or withdrawal would not directly benefit from this specific research.

Why it matters

Potential benefit: If successful, this work could lead to new ways to treat opioid addiction by targeting the specific brain changes that drive dependence and relapse.

How similar studies have performed: While aspects of opioid-induced brain changes are known, this project aims for a more comprehensive and dynamic mapping of specific cell types and circuits, representing a novel integration of approaches.
