Astrocytes: Cell Biology and Pathology of Astrocytes, Volume 3 deals with the involvement of astrocytes in neurological and neuropathological states of brain function.

This volume discusses the expression of astrocyte-specific immunological markers and plasma membrane structures; the dynamics of the cytoskeleton and cell cycle; and the reactivity to injury and response of astrocytes in selected pathological and genetic states. The text also aims to inspire new ideas and research on astrocyte functions as well as on the pathogenesis of neurological disorders.

Neuroscientists, cell biologists, clinicians, neuropathologists, and pediatric neurologists will find the book invaluable.
