How artery smooth muscle cells influence plaque stability

Smooth muscle cell-derived cell fates and cellular interactions in atherosclerotic plaque stability in disease progression and regression.

NIH-funded research Columbia University Health Sciences · NIH-11238976

What this research studies

Researchers will use mouse models and human tissue and blood samples along with advanced single-cell and spatial molecular mapping to see which smooth muscle cell–derived types appear in stable versus unstable plaques. They will follow how smooth muscle cells can become protective fibrochondrocyte-like cells or harmful macrophage-like cells and how those cells interact with macrophages. The team will examine whether oxidative DNA damage shifts cells toward more dangerous identities and whether those changes impair plaque regression. Findings will combine molecular maps and experiments to link specific cell types and interactions to plaque stability.

Who could benefit from this research

Good fit: People with atherosclerotic cardiovascular disease, especially those undergoing vascular procedures or able to donate tissue or blood samples, would be most relevant for participation or sample contribution.

Not a fit: People without atherosclerosis or those seeking immediate changes to their clinical care are unlikely to receive direct benefit from this research.

Why it matters

Potential benefit: If successful, this work could point to new ways to stabilize plaques and lower the risk of heart attacks and strokes.

How similar studies have performed: Prior research shows smooth muscle cells can adopt protective or harmful states, but integrating single-cell and spatial molecular mapping with mouse and human samples to link these states to plaque stability is a more recent approach.
