## 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, astrocytes, 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 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, and endothelial cells throughout the brain. It is constitutively expressed at low levels and upregulated in response to injury, inflammation, and in neurodegenerative diseases.

Key Publications

Expression Pattern

MMP2 (gelatinase A) is constitutively expressed in:

Fibroblasts: Connective tissue cells
Endothelial Cells: Blood vessels
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.

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 permeability
Stroke: Mediates blood-brain barrier breakdown
