Astrocyte morphology [PDF]

open access: yesTrends in Cell Biology, 2023
Astrocytes are predominant glial cells that tile the central nervous system (CNS). A cardinal feature of astrocytes is their complex and visually enchanting morphology, referred to as bushy, spongy, and star-like. A central precept of this review is that

Pharmacological activation of cGMP signaling promotes astrocyte remodeling and enrichment of perivascular GLUT1 in the murine retina [PDF]

open access: yesFrontiers in Cellular Neuroscience
Astrocytes regulate metabolic exchange between the vasculature and neurons in the central nervous system (CNS). In the retina of the eye, also a component of the CNS, astrocyte endfeet couple to vascular elements to mediate glucose uptake via the glucose

A spatial threshold for astrocyte calcium surge

open access: yeseLife
Astrocytes are active cells involved in brain function through the bidirectional communication with neurons, in which astrocyte calcium plays a crucial role.

Activity-dependent switch of GABAergic inhibition into glutamatergic excitation in astrocyte-neuron networks

open access: yeseLife, 2016
Interneurons are critical for proper neural network function and can activate Ca2+ signaling in astrocytes. However, the impact of the interneuron-astrocyte signaling into neuronal network operation remains unknown.

Astrocyte polarization in glaucoma: a new opportunity

open access: yesNeural Regeneration Research, 2022
Astrocyte polarization is a new concept which is similar to microglia polarization and in which astrocytes are classified as A1 (neurotoxic) and A2 (neuroprotective).

Acute treatment with 17β-estradiol attenuates astrocyte-astrocyte and astrocyte-neuron communication

open access: yesGlia, 2007
Astrocytes 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

Astrocyte store-operated calcium entry is required for centrally mediated neuropathic pain [PDF]

open access: yesPAIN Reports
. Introduction:. Acute injuries transition to chronic neuropathic pain through central sensitization (CS), which involves plastic changes to nociceptive networks within the central nervous system.

Exocytosis in Astrocytes [PDF]

open access: yesBiomolecules, 2021
Until recently, astrocytes were thought to be a part of a simple “brain glue” providing only a supporting role for neurons. However, the discoveries of the last two decades have proven astrocytes to be dynamic partners participating in brain metabolism and actively influencing communication between neurons.

Astrocytes and Epilepsy [PDF]

open access: yesNeurotherapeutics, 2010
Astrocytes form a significant constituent of seizure foci in the human brain. For a long time it was believed that astrocytes play a significant role in the causation of seizures. With the increase in our understanding of the unique biology of these cells, their precise role in seizure foci is receiving renewed attention.

The Synucleins and the Astrocyte

open access: yesBiology, 2023
Synucleins consist of three proteins exclusively expressed in vertebrates. α-Synuclein (αS) has been identified as the main proteinaceous aggregate in Lewy bodies, a pathological hallmark of many neurodegenerative diseases. Less is understood about β-synuclein (βS) and γ-synuclein (γS), although it is known βS can interact with αS in vivo to inhibit ...
