Matrix metaloproteinases in vascular pathology.

Area of Science:

• Cardiovascular Biology
• Molecular Medicine
• Biochemistry

Background:

• Vascular diseases are leading causes of death globally.
• The vascular extracellular matrix (ECM) is vital for vascular function, homeostasis, and mechanical support.
• Vascular remodeling, influenced by ECM changes, is linked to aging and cardiovascular pathologies.

Purpose of the Study:

• To provide an overview of matrix metalloproteinases (MMPs) in vascular disease pathogenesis.
• To explore the role of MMPs in arterial hypertension, atherosclerosis, aortic aneurysms, and myocardial infarction.
• To discuss the regulatory balance between MMPs and tissue inhibitors of metalloproteinases (TIMPs).

Main Methods:

• Literature review focusing on MMPs in vascular diseases.
• Analysis of MMPs' role in ECM remodeling and cellular behavior.
• Examination of the MMP/TIMP ratio in vascular pathology.

Main Results:

• MMPs alter ECM composition, creating a pro-inflammatory environment that affects endothelial and smooth muscle cells.
• MMPs are central to tissue repair, remodeling after injury (e.g., myocardial infarction), and disease progression (e.g., atherosclerosis).
• Dysregulation of MMPs contributes to arterial remodeling, hypertension, and aneurysm formation.

Conclusions:

• MMPs play a critical role in the pathogenesis of major vascular diseases.
• The MMP/TIMP balance is a key determinant of ECM degradation and tissue remodeling.
• Targeting MMPs offers potential for improved diagnostics, prognostics, and therapeutics for vascular disorders.
