Astrocytes as Therapeutic Targets in Neurodegenerative Disorders

Area of Science:

• Neuroscience
• Cell Biology
• Genetics

Background:

• Astrocytes are essential for central nervous system (CNS) homeostasis, regulating neuronal activity, immune responses, and the blood-brain barrier.
• Recent studies identify astrocytes as critical players in the pathogenesis of neurodegenerative disorders.
• Key questions persist regarding astrocyte function changes across diseases and their role in disease progression.

Purpose of the Study:

• To review recent findings on astrocyte contributions to neurodegenerative disease onset and progression.
• To highlight the therapeutic potential of targeting astrocyte-specific processes.

Main Methods:

• Review of genetic, transcriptomic, and proteomic studies.
• Analysis of astrocyte reactivity in neurodegenerative cascades.
• Exploration of therapeutic targeting of astrocyte functions.
• Application of omics technologies, murine models, and human-induced pluripotent stem cells (hiPSC) systems.

Main Results:

• Astrocytes exhibit altered functions across various neurodegenerative disorders.
• Astrocyte reactivity is increasingly recognized as a contributor to neurodegenerative processes.
• Targeting astrocyte-specific pathways shows promise for novel therapeutic strategies.

Conclusions:

• Astrocytes are central to understanding and potentially treating neurodegenerative diseases.
