How blood flow affects artery lining cells' cleanup
Impact of hemodynamics on efferocytosis in endothelial cells
This project looks at whether different patterns of blood flow change how artery-lining cells clear away dead cells, which could matter for people with or at risk for artery plaque.

What this research studies
This work uses lab models of artery lining cells exposed to different types of blood flow—low/disturbed flow, steady high flow, and helical flow—to see how those forces change the cells' ability to remove dying cells (efferocytosis). The team will use controlled flow systems and cellular assays, and may confirm findings using animal models or human-derived samples. Results will be connected to processes that drive atherosclerotic plaque buildup in arteries. The goal is to explain how blood flow patterns contribute to artery disease and point to targets that could protect arteries.
Who could benefit from this research
Good fit: People with or at high risk for atherosclerotic cardiovascular disease who can donate blood or tissue samples, especially those near Atlanta, would be the most relevant participants.
Not a fit: Those without artery disease risk factors or people who cannot travel to the research site are unlikely to receive direct benefit from this lab-focused project.
Why it matters
Potential benefit: If successful, this work could reveal new ways to prevent or lessen artery plaque by preserving or boosting the artery lining's ability to clear dead cells.
How similar studies have performed: Prior research shows flow patterns affect endothelial health and that failed clearance by immune cells worsens plaques, but directly linking flow to endothelial efferocytosis is a relatively new area.
