Neuron-astrocyte omnidirectional signaling in neurological health and disease

open access: yesFrontiers in Molecular Neuroscience, 2023
Astrocytes are an abundantly distributed population of glial cells in the central nervous system (CNS) that perform myriad functions in the normal and injured/diseased brain.

The Role of Astrocytes in Synapse Loss in Alzheimer's Disease: A Systematic Review

open access: yesFrontiers in Cellular Neuroscience, 2022
Alzheimer's disease (AD) is the most common cause of dementia, affecting 35 million people worldwide. One pathological feature of progressing AD is the loss of synapses. This is the strongest correlate of cognitive decline.

Electron microscopy analysis of astrocyte-synapse interactions shows altered dynamics in an Alzheimer’s disease mouse model

open access: yesFrontiers in Cellular Neuroscience, 2023
IntroductionAstrocyte-synapse bi-directional communication is required for neuronal development and synaptic plasticity. Astrocytes structurally interact with synapses using their distal processes also known as leaflets or perisynaptic astrocytic ...

Purinergic Tuning of the Tripartite Neuromuscular Synapse

open access: yesMolecular Neurobiology, 2023
AbstractThe vertebrate neuromuscular junction (NMJ) is a specialised chemical synapse involved in the transmission of bioelectric signals between a motor neuron and a skeletal muscle fiber, leading to muscle contraction. Typically, the NMJ is a tripartite synapse comprising (a) a presynaptic region represented by the motor nerve ending, (b) a ...

Hippocampal astrocytes modulate anxiety-like behavior

open access: yesNature Communications, 2022
Astrocytes affect animal behaviors by regulating the tripartite synapse. Here, the authors show that hippocampal astrocytes modulate mouse anxiety-like behavior by regulating synaptic homeostasis of dentate gyrus granule cells via ATP release.

From Synapses to Circuits, Astrocytes Regulate Behavior

open access: yesFrontiers in Neural Circuits, 2022
Astrocytes are non-neuronal cells that regulate synapses, neuronal circuits, and behavior. Astrocytes ensheath neuronal synapses to form the tripartite synapse where astrocytes influence synapse formation, function, and plasticity.

Urokinase-type plasminogen activator (uPA) protects the tripartite synapse in the ischemic brain via ezrin-mediated formation of peripheral astrocytic processes. [PDF]

open access: yesJ Cereb Blood Flow Metab, 2019
Cerebral ischemia has a harmful effect on the synapse associated with neurological impairment. The “tripartite synapse” is assembled by the pre- and postsynaptic terminals, embraced by astrocytic elongations known as peripheral astrocytic processes ...

Calcium signaling in astrocytes and gliotransmitter release

open access: yesFrontiers in Synaptic Neuroscience, 2023
Glia are as numerous in the brain as neurons and widely known to serve supportive roles such as structural scaffolding, extracellular ionic and neurotransmitter homeostasis, and metabolic support.

Cyclic AMP response element-binding protein (CREB) transcription factor in astrocytic synaptic communication

open access: yesFrontiers in Synaptic Neuroscience, 2023
Astrocytes are known to actively participate in synaptic communication by forming structures called tripartite synapses. These synapses consist of presynaptic axon terminals, postsynaptic dendritic spines, and astrocytic processes where astrocytes ...
