Astrocyte in Neurological Disease: Pathogenesis and Therapy

Area of Science:

• Neuroscience
• Cell Biology
• Pathology

Background:

• Astrocytes are crucial glial cells in the central nervous system, maintaining brain homeostasis.
• Astrocyte dysfunction is implicated in major neurological diseases, including Alzheimer's, Parkinson's, multiple sclerosis, and stroke.

Purpose of the Study:

• To comprehensively review the dual roles of astrocytes in neurological disease pathogenesis.
• To summarize current and emerging therapeutic strategies targeting astrocytes.

Main Methods:

• Literature review and synthesis of recent research findings on astrocyte function and dysfunction in neurological diseases.
• Analysis of therapeutic interventions targeting astrocyte activation, metabolism, and genetic pathways.

Main Results:

• Aberrant astrocyte activation can worsen disease by promoting neuroinflammation, synaptic dysfunction, and blood-brain barrier disruption.
• Astrocyte metabolic disorders, including lipid accumulation and mitochondrial dysfunction, contribute to neurodegeneration.
• Targeting astrocyte phenotype, metabolism, gene therapy, exosomes, and nanotechnology show therapeutic potential.

Conclusions:

• Astrocytes exhibit complex, dual roles in neurological diseases, acting as both detrimental and potentially beneficial players.
• Modulating astrocyte behavior and metabolism presents a promising avenue for developing novel therapeutic strategies for neurodegenerative conditions.
