Multiple roles of metalloproteinases in neurological disorders

Area of Science:

• Neuroscience
• Biochemistry

Background:

• Metalloproteinases, including Matrix metalloproteinases (MMPs) and A disintegrins and metalloproteinases (ADAMs), are vital enzymes in the central nervous system.
• These enzymes play roles in extracellular matrix remodeling, neurogenesis, and angiogenesis during development.
• Dysregulation of MMPs and ADAMs is implicated in neuroinflammatory conditions and neurodegenerative diseases.

Purpose of the Study:

• To review the multifaceted roles of MMPs and ADAMs in the central nervous system.
• To highlight their involvement in both normal physiological processes and pathological conditions.
• To explore emerging research on their intranuclear functions and therapeutic potential.

Main Methods:

• Literature review of studies on metalloproteinases in the nervous system.
• Analysis of the functions of MMPs, ADAMs, and their inhibitors (TIMPs).
• Examination of the involvement of these enzymes in neuroinflammation, blood-brain barrier integrity, and neurodegeneration.

Main Results:

• MMPs and ADAMs are critical for brain development, neuroinflammation, and maintaining blood-brain barrier integrity.
• ADAMs contribute to neuroinflammation via TNF-α activation and receptor modulation.
• Recent findings reveal intranuclear roles for MMPs in DNA repair.
• MMPs and ADAMs are implicated in Alzheimer's disease and vascular cognitive impairment.

Conclusions:

• MMPs and ADAMs exhibit diverse and significant functions within the central nervous system.
• Their roles extend from extracellular matrix regulation to intranuclear DNA repair.
• Further research into MMPs and ADAMs presents promising avenues for novel therapeutic strategies in neurological diseases.
