Astrocytes are central nervous system (CNS) glial cells with many important functions for normal development and neural functioning. They help control extracellular ion and neurotransmitter concentrations; provide neurotrophic support; are implicated in synapse formation, function, and pruning; and help maintain the blood-brain barrier. Following injury and in disease, they undergo rapid and chronic alterations in function that can either promote or hinder recovery, depending on the disease.
