Alexander Disease
Astrocytes, named for their characteristic star-like shape, are supportive cells of the central nervous system. Astrocytes surround neurons, the functional unit of the central nervous system, nourishing, protecting, and repairing them from stress or injury, as well as enhancing their function. In Alexander disease, astrocyte function is compromised.
