Gene activity in the habenula of people with opioid addiction and depression
Regulation of Gene Expression in the Human Habenula in Comorbid Opioid Addiction and Depression
This work looks at which genes are active in a small brain region called the habenula to learn how it differs in people with opioid addiction, major depression, or both.

What this research studies
This project will create detailed maps showing which genes are active in each cell and exact spots within the human habenula using advanced single-cell and spatial gene technologies on donated brain tissue. It will compare samples from people who had opioid addiction, major depression, both conditions, and people without these disorders to spot cell types and areas with differences. The team will link those differences to genetic and epigenetic signals that affect serotonin and dopamine systems tied to mood and reward. From your perspective, these maps aim to point researchers toward specific targets for future treatments or tests for people with co-occurring addiction and depression.
Who could benefit from this research
Good fit: Ideal candidates are people with a history of opioid addiction, major depressive disorder, or both, and individuals who are willing to donate brain tissue for research after death.
Not a fit: People without opioid addiction or depression or those seeking immediate clinical treatment are unlikely to receive direct benefit from this mapping work.
Why it matters
Potential benefit: If successful, this could reveal specific cell types and genes to target for new treatments or diagnostics for people with opioid addiction and depression.
How similar studies have performed: Single-cell and spatial mapping methods have produced useful disease-linked maps in other brain regions, but applying them to the human habenula in comorbid opioid addiction and depression is largely novel.
