Reprogramming blood-vessel lining cells in inherited brain aneurysms

Endothelial Cell Reprogramming in Familial Intracranial Aneurysm

NIH-funded research Yale University · NIH-11258496

This project aims to find out whether fixing gene-related changes in the cells that line brain arteries can lower aneurysm risk in people with a family history.

What this research studies

You may be asked to share family and medical history and provide a blood sample for genetic sequencing. Researchers will compare genes from families with multiple aneurysms to find rare mutations, including changes in WBP11 and PPIL4. They will study how those mutations change the behavior of the cells that line brain blood vessels using lab-grown human cells and animal models to see why vessel walls weaken and bleed. The team hopes to use those findings to point to tests or new treatments that could help prevent aneurysm formation or rupture.

Who could benefit from this research

Good fit: Adults (21+) with a personal diagnosis of intracranial aneurysm or a strong family history of brain aneurysms, especially families with multiple affected relatives, are the ideal candidates.

Not a fit: People without a hereditary form of aneurysm or those needing immediate clinical treatment to stop an active leak are unlikely to receive direct clinical benefit from this lab-focused genetic research right away.

Why it matters

Potential benefit: If successful, this work could identify people at higher hereditary risk and point to new ways to protect vessel walls or prevent aneurysm rupture.

How similar studies have performed: Previous genetic and animal studies have linked gene changes to aneurysm biology, but the roles of WBP11 and PPIL4 are newly identified and targeting them in patients remains untested.
