PAR2 role in abdominal aortic aneurysm development

Official title: The role of protease activated receptor 2 in the initiation and progression of abdominal aortic aneurysm

Funded at University of Cincinnati · NIH-11332797 · Data updated 2026-11-12

Researchers are studying how a specific receptor (PAR2) in blood vessels might contribute to the development and progression of abdominal aortic aneurysms, with potential pathways to new treatments for people with the condition.

Who could benefit from this research

Could help

Adults 21 years and older who have or are at risk for abdominal aortic aneurysm, particularly those 65 and older.

Less likely to help

The study is more focused on mechanisms; individuals without AAA or at low risk may not directly benefit.

What this research studies

This project explores how the protease-activated receptor 2, a seven‑transmembrane receptor, may drive inflammation and vessel wall changes in abdominal aortic aneurysm. Using models of AAA and human tissue data, the study examines how PAR2 affects vascular cells and immune signals, aiming to identify mechanisms that could be targeted by new drugs. If successful, findings could point toward non-surgical options to slow or prevent aneurysm growth and rupture. The research involves detailed cellular analysis and animal or tissue-based experiments to connect PAR2 activity with aneurysm biology and patient-relevant outcomes.

Why it matters

Potential benefit: Could lead to new drug targets to treat or prevent abdominal aortic aneurysm and reduce risk of rupture.

How similar studies have gone: Previous work in related vascular disease models suggests PAR2 can influence vascular inflammation and remodeling, making this approach promising but still investigational.
