What this research studies

This project studies how small airborne chemicals (VOCs) can cause stress inside blood-vessel cells and change metabolism in ways that raise heart disease and diabetes risk. Scientists use cell experiments and animal models to trace the molecular steps, including a stress response in cells called the unfolded protein response. The team is also looking for blood or tissue signals (biomarkers) that show VOC exposure or early vascular injury. Finally, they will test laboratory strategies to neutralize reactive breakdown products and reduce the harmful effects on blood vessels and metabolism.

Who could benefit from this research

Good fit: Adults aged 21 and older who have or are at risk for atherosclerotic cardiovascular disease or type 2 diabetes, or who have known exposure to volatile organic pollutants, would be the most relevant people for this work.

Not a fit: Children under 21 and people without VOC exposure or without cardiometabolic risk factors are unlikely to receive direct benefit from this project.

Why it matters

Potential benefit: If successful, the work could identify markers to detect VOC-related vascular harm earlier and point to ways to prevent or treat pollution-driven heart and metabolic disease.

How similar studies have performed: Early laboratory and animal studies suggest VOCs can trigger cellular stress linked to metabolic and vascular problems, but interventions to prevent these effects in people remain largely unproven.
