Summary
Matrix metalloproteinases (MMPs) from macrophages weaken atherosclerotic plaques, increasing rupture risk. Selective MMP inhibition or gene transfer may offer better atherosclerosis treatment than current broad-spectrum inhibitors.
Area of Science:
- Cardiovascular Biology
- Biochemistry
- Pathology
Background:
- Atherosclerotic plaques feature lipid cores and fibrous caps.
- Plaque rupture causes acute myocardial infarction via thrombosis.
- Macrophage foam cells in plaques correlate with matrix-degrading metalloproteinases (MMPs) and weakened fibrous caps.
Purpose of the Study:
- Investigate the role of macrophage-derived MMPs in atherosclerotic plaque weakening.
- Evaluate MMP inhibition as a therapeutic strategy for atherosclerosis.
Main Methods:
- Analysis of atherosclerotic plaque composition and macrophage infiltration.
- Correlation of MMP activity with fibrous cap integrity.
- Review of studies on MMP inhibitors for atherosclerosis treatment.
Main Results:
- Macrophage accumulation is linked to increased MMPs and reduced fibrous cap strength.
- MMPs are implicated in weakening plaque structures, promoting rupture.
- Current non-specific MMP inhibitors have yielded inconclusive clinical results.
Conclusions:
- Macrophage-derived MMPs play a critical role in atherosclerotic plaque instability.
- Selective MMP inhibitors or gene transfer strategies show promise for atherosclerosis treatment.
- Targeted approaches may overcome limitations of current non-specific MMP inhibitors.

Role of Matrix Metalloproteases in Degradation of ECM
Matrix metalloproteases (MMPs) are enzymes involved in the hydrolysis of proteins and glycoproteins of the extracellular matrix. MMPs are essential for the migration and proliferation of cells through the dense matrix network, throughout embryonic development, and throughout morphogenesis. The first MMP activity discovered was a collagenase in a tadpole's tail undergoing metamorphosis. The active collagen deposition and modifications lead to the morphogenesis of tadpoles into the adult body.

Atherosclerosis I: Introduction
Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...
