Understanding how sleep patterns affect cravings for fentanyl

Novel roles for the circadian transcription factor NPAS2 and striatal dopamine D3 receptor signaling in diurnal fentanyl craving and relapse

NIH-funded research Univ of Massachusetts Med Sch Worcester · NIH-11133020

This study is looking at how sleep problems might make people with opioid use disorder crave fentanyl more, and it’s exploring a protein that helps control our sleep-wake cycles to see how it affects brain signals related to cravings, with the hope of finding ways to improve sleep and reduce those cravings.

What this research studies

This research investigates the relationship between sleep disturbances and cravings for fentanyl in individuals with opioid use disorder. It focuses on the role of a specific protein, NPAS2, which is involved in regulating circadian rhythms and how it affects dopamine signaling in the brain. By studying these mechanisms, the research aims to uncover how disruptions in sleep can lead to increased cravings and relapse into opioid use. The findings could help develop targeted interventions to improve sleep and reduce cravings.

Who could benefit from this research

Good fit: Ideal candidates for this research are individuals diagnosed with opioid use disorder who experience significant sleep disturbances.

Not a fit: Patients who do not have opioid use disorder or those without sleep-related issues may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to new treatments that help manage cravings and reduce relapse rates in individuals recovering from opioid addiction.

How similar studies have performed: Previous research has shown promising results in understanding the link between circadian rhythms and substance use disorders, suggesting that this approach could yield valuable insights.
