Summary
Matrix metalloproteinases (MMPs) are key molecular players in arterial diseases like atherosclerosis. This review examines evidence linking MMPs to all stages of atherosclerosis, from initiation to plaque rupture and thrombosis.
Area of Science:
- Cardiovascular Biology
- Molecular Medicine
- Proteomics
Background:
- Arterial diseases, including atherosclerosis, represent a significant global health burden.
- Matrix metalloproteinases (MMPs) are a family of enzymes involved in extracellular matrix degradation.
- Emerging evidence implicates MMPs in the pathogenesis of various cardiovascular conditions.
Purpose of the Study:
- To review the current evidence on the role of matrix metalloproteinases (MMPs) in arterial biology.
- To highlight the involvement of MMPs in the different stages of atherosclerosis.
- To discuss the activation of MMPs within atherosclerotic plaques.
Main Methods:
- Comprehensive literature review of studies on MMPs and arterial diseases.
- Analysis of findings from human pathological specimens.
- Integration of data from animal models, cell biology, and molecular biology research.
Main Results:
- Matrix metalloproteinases (MMPs) are implicated in lesion initiation and progression in atherosclerosis.
- MMPs play a critical role in atherosclerotic plaque complication and the triggering of thrombosis.
- The proteolytic cascade involving MMPs offers multiple levels of functional control.
Conclusions:
- Matrix metalloproteinases (MMPs) are central molecular mediators in the development and progression of arterial diseases.
- Understanding MMP activation in atherosclerotic plaques is crucial for therapeutic strategies.
- Further research into MMPs' complex roles may yield novel treatments for atherosclerosis.
