Abstract
Abdominal aortic aneurysm (AAA) is a critical condition characterized by the expansion of the infrarenal aorta, often leading to high mortality upon rupture. The absence of treatment for asymptomatic AAAs urgently necessitates uncovering the underlying mechanisms of their development. This study utilized mice to induce AAA through porcine pancreatic elastase with BAPN feeding and found that mice receiving the IRF5-binding peptide (IBP) demonstrated significantly slowed AAA expansion and reduced adventitia degradation compared to the control group. Additionally, the IBP group showed decreased macrophage infiltration and reduced matrix metalloproteinase-9 (MMP9) activity. Targeting IRF5 with IBP offers new avenues for potential treatments for asymptomatic AAAs.
期刊介绍:
The Journal of Molecular and Cellular Cardiology publishes work advancing knowledge of the mechanisms responsible for both normal and diseased cardiovascular function. To this end papers are published in all relevant areas. These include (but are not limited to): structural biology; genetics; proteomics; morphology; stem cells; molecular biology; metabolism; biophysics; bioengineering; computational modeling and systems analysis; electrophysiology; pharmacology and physiology. Papers are encouraged with both basic and translational approaches. The journal is directed not only to basic scientists but also to clinical cardiologists who wish to follow the rapidly advancing frontiers of basic knowledge of the heart and circulation.
