Who could benefit from this research

Could help

People living with HIV, especially those taking protease inhibitor–based ART or who are concerned about heart disease, would be the ideal candidates to engage with this work.

Less likely to help

People without HIV or whose heart problems are caused by unrelated conditions are unlikely to benefit directly from this research.

What this research studies

From your perspective, the team wants to know if some antiretroviral drugs make platelets release a protein (TGFβ1) that leads to scarring in the heart. They will measure TGFβ1 and platelet activity in blood samples, use lab and mouse models that carry HIV-like genes, and link those findings to signs of cardiac fibrosis. Early work showed protease-inhibitor regimens can trigger TGFβ1 release and more heart scarring in mice, so researchers will also test whether blocking a platelet transporter (MRP4) can stop that process. The goal is to find whether changes in treatment or drugs that block this pathway could prevent heart damage in people with HIV.

Why it matters

Potential benefit: Could identify which HIV treatments raise heart risk and suggest ways to prevent heart scarring and sudden deaths in people with HIV.

How similar studies have gone: Prior human observations and pilot animal studies link higher plasma TGFβ1 and cardiac fibrosis to HIV and some ARTs, and blocking platelet MRP4 showed promise in early preclinical work, but translating this to patient prevention is new.
