Extracellular matrix remodelling in neurological diseases

Area of Science:

• Neuroscience
• Biochemistry
• Cell Biology

Background:

• The neural extracellular matrix (ECM) comprises proteins and glycans forming structures like perineuronal nets.
• ECM regulates synaptic stability, plasticity, and network excitability in the central nervous system (CNS).
• ECM plays a critical role in memory engrams and cognitive flexibility.

Purpose of the Study:

• To review the role of ECM in CNS diseases.
• To explore ECM remodelling mechanisms and therapeutic potential.
• To highlight emerging technologies for ECM research.

Main Methods:

• Literature review of behavioural studies, preclinical models, and technological advancements.
• Analysis of ECM's role in various CNS conditions, including trauma, stroke, and chronic disorders.
• Examination of factors driving ECM remodelling, such as neuronal activity and neuroinflammation.

Main Results:

• ECM remodelling is a common feature in CNS diseases, with condition-specific patterns.
• ECM-targeting treatments have demonstrated efficacy in preclinical CNS disease models.
• Novel biochemical and imaging technologies are advancing ECM research.

Conclusions:

• The neural ECM is a critical regulator of brain function and cognition.
• ECM remodelling presents a significant therapeutic target for neurological disorders.
• Future research utilizing advanced technologies holds promise for novel ECM-based therapies and biomarkers.
