Who could benefit from this research

Could help

People living with HIV who are virologically controlled on antiretroviral therapy and may have elevated inflammation or cardiovascular risk.

Less likely to help

If you do not have HIV or are not on effective HIV therapy, this study is not about your health.

What this research studies

This project investigates how cell-free hemoglobin carried in extracellular vesicles from red blood cells might drive chronic inflammation, clotting, and endothelial problems in people living with HIV who are on effective therapy. The team will study how these plasma vesicles interact with endothelial cells and platelets to uncover mechanisms that could raise cardiovascular risk. By using patient samples and relevant lab models, the research seeks to identify new, translational approaches to reduce inflammation and thrombosis in HIV. The work could point toward novel therapies or biomarkers to better protect heart health in PWH.

Why it matters

Potential benefit: If successful, the research could lead to new strategies to lower cardiovascular risk and improve immune health for people living with HIV.

How similar studies have gone: Prior studies suggest extracellular vesicles and cell-free hemoglobin may influence vascular and immune processes, but this specific link in HIV is exploratory and novel.
