AbstractIt is becoming apparent that astrocytes carry out a large number of different functions in brain and are able to modify their characteristics throughout life, that is they exhibit a high degree of plasticity in their phenotype. For example, the morphology of astrocytes changes markedly during neuronal migration, maturation, and degeneration. It

Astroglia represent the highly heterogeneous population of neuroglial cells in the central nervous system (CNS). The main function of astroglial cells lies in preservation of brain homeostasis. Astroglial cells are involved in the regulation of neurogenesis and neural cell development; they control synaptogenesis, maintenance, and pruning of synapses ...

AbstractSeveral studies have demonstrated the presence of perinodal astrocyte processes at nodes of Ranvier in the central nervous system, suggesting that, in addition to the axon and oligodendrocyte, astrocytes participate in the formation of mature central nodes.

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.

Primary astrocyte cultures?a key to astrocyte function
Cellular and Molecular Neurobiology, 1983Morphological studies have established the ubiquitous nature of astrocytes in the CNS. Their processes surround capillaries and synapses, form the subpial and subependymal layers, and seemingly invest every neuronal surface not covered by other neuronal surfaces or oligodendroglial membranes.

Astrocyte dysfunction in epilepsy
Brain Research Reviews, 2010Epilepsy comprises a group of disorders characterized by the periodic occurrence of seizures. Currently available anticonvulsant drugs and therapies are insufficient to controlling seizure activity in about one third of epilepsy patients. Thus, there is an urgent need for new therapies that prevent the genesis of the disorder and improve seizure ...

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.

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 ...
