Role of astrocytes in major neurological disorders: the evidence and implications

Given the huge amount and great complexity of astrocyte functions in the maintenance of brain homeostasis, it is easily understood how alterations in their physiology may be involved in the pathogenesis of many, if not all, neurological disorders. This assumption is strongly supported by accumulated evidence produced in humans and in experimental models of pathology. Based on these considerations, it is reasonable to encourage studies aimed at improving the knowledge about the implicated mechanisms, and astroglial cells can be considered as the innovative target for new, and possibly more effective, drug therapies.
