Overview
The MMP2 (Matrix Metallopeptidase 2) gene encodes a zinc-dependent endopeptidase also known as gelatinase A. This enzyme degrades extracellular matrix components including gelatin, type IV collagen, and elastin. In the brain, MMP-2 is expressed in [neurons](/entities/neurons), astrocytes, [microglia](/entities/microglia), and endothelial cells where it regulates synaptic plasticity, blood-brain barrier integrity, and neuroinflammation. Elevated MMP-2 activity has been documented in Alzheimer's disease, Parkinson's disease, multiple sclerosis, and following traumatic brain injury.

Overview
The MMP2 (Matrix Metallopeptidase 2) gene encodes a zinc-dependent endopeptidase also known as gelatinase A. This enzyme degrades extracellular matrix components including gelatin, type IV collagen, and elastin. In the brain, MMP-2 is expressed in [neurons](/entities/neurons), astrocytes, [microglia](/entities/microglia), and endothelial cells where it regulates synaptic plasticity, blood-brain barrier integrity, and neuroinflammation. Elevated MMP-2 activity has been documented in Alzheimer's disease, Parkinson's disease, multiple sclerosis, and following traumatic brain injury.
Matrix metallopeptidase 2 (MMP-2) is a zinc-dependent endopeptidase that degrades extracellular matrix components. It is involved in tissue remodeling, wound healing, and has been implicated in neurodegenerative diseases.
Function
MMP-2 (gelatinase A) degrades gelatin (denatured collagen), type IV collagen, and elastin. It is secreted as a proenzyme and activated by proteolytic cleavage. MMP-2 plays roles in synaptic plasticity, blood-brain barrier remodeling, and neuroinflammation. In AD, MMP-2 may contribute to [Aβ](/proteins/amyloid-beta) degradation but also to pathological remodeling. In PD, MMP-2 is involved in dopaminergic neuron survival. Elevated MMP-2 activity is observed in multiple neurological disorders.
Disease Associations
Alzheimer's Disease; Parkinson's Disease; Multiple Sclerosis; Brain Injury; Vascular Dementia
Expression
MMP-2 is expressed in neurons, astrocytes, [microglia](/cell-types/microglia-neuroinflammation), and endothelial cells throughout the brain. It is constitutively expressed at low levels and upregulated in response to injury, inflammation, and in neurodegenerative diseases.

Expression Pattern
MMP2 (gelatinase A) is constitutively expressed in:
- Fibroblasts: Connective tissue cells
- Endothelial Cells: Blood vessels
- [Astrocytes](/entities/astrocytes): CNS tissue
- Macrophages: Immune cells
MMP2 is unique among MMPs because it is produced as an inactive proenzyme and requires activation by other proteases or [reactive oxygen species](/entities/reactive-oxygen-species).
Disease Associations
MMP2 in neurodegeneration:
- Alzheimer's Disease: Degrades Aβ; altered in AD brain
- Parkinson's Disease: Involved in dopaminergic neuron survival
- Multiple Sclerosis: Regulates [BBB](/entities/blood-brain-barrier) permeability
- Stroke: Mediates blood-brain barrier breakdown
Therapeutic Approaches
| Approach | Status | Description |
|----------|--------|-------------|
| Broad-spectrum MMP inhibitors | Discontinued | Failed due to lack of selectivity |
| MMP2-selective inhibitors | Research | Developing more specific compounds |
| TIMP2 overexpression | Preclinical | Endogenous inhibitor delivery |
Background
The study of Mmp2 Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
