CLCA1 protein blocking inflammation in abdominal aortic aneurysms

Role of CLCA1 as a MIF decoy inhibitor in abdominal aortic aneurysms

NIH-funded research Brigham and Women's Hospital · NIH-11300262

Researchers are looking at whether a protein called CLCA1 can block harmful inflammation driven by MIF in people with abdominal aortic aneurysms.

What this research studies

This work examines how the protein CLCA1 binds to the inflammatory molecule MIF and whether that interaction protects the aortic wall. The team uses cultured vascular cells and animal models to see if CLCA1 can act as a decoy and reduce immune-driven damage in the aorta. They measure changes in vessel structure, immune cell behavior, and inflammatory signals that relate to aneurysm growth. Results could identify a new biological target for therapies to slow or prevent aneurysm progression.

Who could benefit from this research

Good fit: People diagnosed with an abdominal aortic aneurysm or considered at high risk for AAA would be the most relevant group for future trials.

Not a fit: People without aortic disease, or those who already had their aneurysm surgically repaired, are unlikely to benefit directly from this laboratory-focused work in the short term.

Why it matters

Potential benefit: If successful, the research could point to new treatments that reduce inflammation and slow or prevent growth of abdominal aortic aneurysms.

How similar studies have performed: Previous research supports that MIF drives artery inflammation and aneurysm formation, but using CLCA1 as a decoy inhibitor is a novel approach that has not yet been tested in patients.
