Immune and metabolic gene patterns tied to depression in people with HIV
Immunometabolicgene expression profiles associated with depressed mood and behavioral domains inpeople with HIV
This project looks at immune and metabolism-related genes to find links to low mood and loss of pleasure in adults living with HIV.

What this research studies
You would give blood samples and complete questionnaires and cognitive tests about mood and pleasure. Researchers will use RNA sequencing and protein biomarker tests to measure immune and metabolic gene activity, focusing on the mTOR and NLRP3 pathways. They will compare results from about 80 people with HIV to 40 age-matched people without HIV to find patterns tied to anhedonia and treatment-resistant depression. The goal is to connect specific gene and protein signals with the clinical symptoms of depression in people with HIV.
Who could benefit from this research
Good fit: Adults living with HIV, especially those experiencing depressive symptoms like loss of pleasure, who can attend study visits at the site, are ideal candidates.
Not a fit: People without HIV or those whose depression has causes unrelated to immune or metabolic changes may not benefit directly from this work.
Why it matters
Potential benefit: If successful, this work could point to new immune- or metabolism-targeted approaches to treat depression in people living with HIV.
How similar studies have performed: Previous research and the investigators' preliminary data suggest immune–metabolic links to depression, but targeted treatments for depression in people with HIV are not yet established.
