Astrocytes contribute to the maintenance of the health and function of the
central nervous system (CNS). Thus, it is not surprising that these
multifunctional cells have been implicated in the onset and progression of
several neurodegenerative diseases. The involvement of astrocytes in the
neuropathology of these diseases is likely a consequence of both the loss of
normal homeostatic functions and gain of toxic functions. Intracellular
aggregates in astrocytes are a common feature of various neurodegenerative
diseases, and these aggregates perturb normal astrocytic functions in ways that
can be harmful to neuronal viability. Here, we review the role of astrocytes in
neurodegenerative diseases, focusing on their dysfunction in Huntington's disease
(HD), Parkinson's disease (PD), Alzheimer's disease (AD), and amyotrophic lateral
sclerosis (ALS).
