Astrocytic gliomas are the most common primary brain tumors and account for up to two thirds of all tumors of glial origin. In this review we outline the basic histological and epidemiological aspects of the different astrocytoma subtypes in adults. In addition, we summarize the key genetic alterations that have been attributed to astrocytoma patho ...

Astrocytes and Astrocyte–Neuron Interactions
2021Abstract Astrocytes constitute approximately 30 percent of cells in the CNS and are the most abundant glial cells. They constitute a structural and functionally heterogeneous population and are critically involved in development, homeostasis, synaptic and neuronal network activity, and response to injury and repair in the CNS.

Acute treatment with 17β‐estradiol attenuates astrocyte–astrocyte and astrocyte–neuron communication
Glia, 2007AbstractAstrocytes are now recognized as dynamic signaling elements in the brain. Bidirectional communication between neurons and astrocytes involves integration of neuronal inputs by astrocytes and release of gliotransmitters that modulate neuronal excitability and synaptic transmission.

Astrocytes belong to an extended class of astroglia, a class of neural cells of ectodermal, neuroepithelial origin that sustain homeostasis and provide for defense of the brain and the spinal cord. Astroglial cells support homeostasis of the central nervous system at all levels of organization from molecular to organ-wide.

Astrocytes play diverse roles in central nervous system (CNS) function and dysfunction, and the connections that the astrocyte makes with other cells of the brain are essential for a variety of important neural tasks. Bringing together contributions from international experts at the top of their field, Astrocytes: Wiring the Brain emphasizes ...

Abstract The close anatomical association between astrocytes and neurons has long been suggestive of some functional interplay between these cells. However, the structural complexity of the CNS has often precluded definitive studies of astrocytes in vivo.
