How blood flow controls the ALK1/ENG pathway in blood vessel health and disease

Flow regulation of the Alk1/Eng pathway in vascular homeostasis and disease

NIH-funded research Yale University · NIH-11097342

This project looks at how blood flow changes a key ALK1/ENG signaling pathway in blood vessels to find ways to prevent or fix dangerous vessel malformations and poor artery remodeling.

What this research studies

The team will examine how the force of blood flow alters signals in endothelial cells through the ALK1/ENG pathway using molecular experiments and laboratory models. They plan to map a two-state regulatory network that determines whether vessels remain stable or undergo outward remodeling that can be normal or lead to arteriovenous malformations (AVMs). Using those findings they will test control points in preclinical models to identify molecular targets. The aim is to translate these discoveries into therapies that can stabilize vessels or promote healthy widening where needed.

Who could benefit from this research

Good fit: Adults with hereditary hemorrhagic telangiectasia (HHT) who have arteriovenous malformations or adults with coronary or peripheral artery disease and impaired vessel remodeling would be the most likely candidates.

Not a fit: People without vascular disease, children unless later included, or patients whose condition is unrelated to the ALK1/ENG pathway are unlikely to benefit directly from this project.

Why it matters

Potential benefit: If successful, this work could lead to new treatments that prevent or reverse vessel malformations in HHT and improve arterial remodeling after blockages.

How similar studies have performed: Prior research has linked ALK1/ENG to HHT, but using flow-responsive control points as therapeutic targets is a newer and less-tested approach.
