Astroglia in neurological diseases

Area of Science:

• Neuroscience
• Cell Biology
• Pathology

Background:

• Astroglia are crucial glial cells in the mammalian brain, maintaining homeostasis.
• Dysfunctional brain homeostasis underlies neurological and psychiatric disorders, implicating astrocytes in these conditions.

Purpose of the Study:

• To survey the roles of astrocytes as homeostatic cells in both healthy and diseased mammalian brains.
• To discuss the involvement of astrocytes in various neuropathologies.

Main Methods:

• Literature review and synthesis of existing research on astrocyte function in health and disease.
• Discussion of specific pathological conditions involving astrocytes.

Main Results:

• Astrocytes exhibit dynamic responses to brain insults, including hypertrophy (astrogliosis) and, in some cases, atrophy.
• Astrocytes play roles in Alexander disease, Alzheimer's disease, amyotrophic lateral sclerosis, stroke, and epilepsy.

Conclusions:

• Astrocytes are central to brain homeostasis and are involved in a wide spectrum of brain disorders.
• Modulating astrocyte function presents a potential novel therapeutic strategy for treating brain diseases.
