A thoracic aortic aneurysm (TAA) is a dangerous bulge in the main artery leaving the heart. It can tear (dissection) or rupture, and these events are major causes of illness and death in the United States.

What they work on

  1. Define the molecular triggers and downstream effects of CART signaling in human aortic smooth muscle cells in vitro, testing whether it drives wall remodeling and medial calcification, mineral buildup that stiffens the artery.
  2. Determine the role of sexually dimorphic signaling in thoracic aortic aneurysm in vivo, using bioengineered human vascular grafts made with human-derived smooth muscle cells.
  3. Produce high-resolution spatial maps of male and female aneurysm tissue using single-molecule spatial transcriptomics on surgically removed samples, as a reference for the sex-specific cell types identified, including CARTPT-expressing cells.

More about the research

Aneurysms grow differently in men and women and have different outcomes, but no one knows why. Most patients have no family history of the disease, and the only treatment is surgery, because the disease process in humans is poorly understood.

Why it matters

No drugs currently treat thoracic aortic aneurysm, and patients rely on surgery to prevent life-threatening dissection and rupture. Explaining why the disease differs between men and women, especially the role of CART signaling and medial calcification, could point to sex-specific treatment targets and better prevention and management.
