Animal behavior was classically considered to be determined exclusively by neuronal activity, whereas surrounding glial cells such as astrocytes played only supportive roles. However, astrocytes are as numerous as neurons in the mammalian brain, and current findings indicate a chemically based dialog between astrocytes and neurons.

Ageing is associated with a morphological and functional decline of astrocytes with a prevalence of morphological atrophy and loss of function. In particular, ageing is manifested by the shrinkage of astrocytic processes: branches and leaflets, which decreases synaptic coverage.

Astrocytes are a unique and dynamic subtype of glial cells in the central nervous system (CNS). Understanding their biochemical reactions and their influence in the surrounding cells is extremely important in the neuroscience field. They exert important influence in the neurotransmission, ionic homeostasis and also release neuroactive molecules termed ...

Changes in astrocyte channels, transporters, and metabolism play a critical role in seizure generation and epilepsy. In particular, alterations in astrocyte potassium, glutamate, water and adenosine homeostasis and gap junctional coupling have all been associated with hyperexcitability and epileptogenesis (largely in temporal lobe epilepsy).

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.
