Examining how THC affects immune responses in HIV-infected and healthy individuals

In Vivo Study of THC-induced Immune-genome Changes At Single Cell Solution in HIV-infected Humans

Phase 1 Interventional Yale University · NCT04920539

This study is testing how THC affects the immune system in both people with HIV and those who are healthy to see if there are any differences in how it works.

What this trial studies

This study investigates the effects of THC on the immune genome at a single-cell level in both HIV-infected and uninfected individuals. The researchers aim to understand how THC alters cytokine production through epigenetic mechanisms and whether these changes differ between the two groups. By administering THC and analyzing peripheral blood mononuclear cells, the study seeks to link epigenomic and transcriptomic changes to genomic variants, providing insights into THC's impact on immune responses.

Who should consider this trial

Good fit: Ideal candidates include HIV-positive individuals with good medication adherence and HIV-negative individuals in good health.

Not a fit: Patients with major medical conditions or those who are pregnant or lactating may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to new therapeutic strategies for managing immune responses in HIV-infected patients.

How similar studies have performed: While studies on THC's effects on the immune system exist, this specific approach examining single-cell alterations in the context of HIV is relatively novel.
