APP/Aβ Signaling Orchestrates Reactive Astrocyte Networks in Alzheimer's Disease
Stress increases astrocyte APP production, generating amyloid‐β (Aβ). Aβ then diffuses to neighboring astrocytes, stimulating further APP and Aβ production and creating a self‐reinforcing cycle. Over time, impaired Aβ clearance leads to its accumulation, chronic inflammation, and contributes to sporadic Alzheimer's disease. ABSTRACT Alzheimer's disease

Two modes of enteric gliotransmission differentially affect gut physiology [PDF]
AbstractEnteric glia (EG) in the enteric nervous system can modulate neuronally regulated gut functions. Using molecular genetics, we assessed the effects that molecular entities expressed in EG and otherwise mediating two distinct mechanisms of gliotransmitter release, connexin 43 (Cx43) hemichannel vs. Ca2+‐dependent exocytosis, have on gut function.

Astrocytes from the hippocampus of chronic epileptic rats exhibit an abnormal pattern of intracellular calcium oscillations, characterized by an augmented frequency of long lasting spontaneous Ca2+ transients, which are sensitive to purinergic receptor ...

Modulation of K2P and Kv7 channels has the potential to reduce hyperexcitability and hypersynchronicity within the thalamocortical system. This offers a new avenue to suppress spike and wave discharges, the electrophysiological hallmark of absence epilepsy.

Components and properties of Ca2+ buffers in astrocytes, which should be considered for data interpretation and in computational modeling of astrocyte Ca2+ activity. ABSTRACT Astrocytic Ca2+ signaling is essential for maintaining physiological brain function, including the modulation of synaptic transmission, neurovascular coupling, and ion homeostasis.

GABA release by hippocampal astrocytes
Astrocytes can directly influence neuronal activity through the release of various transmitters acting on membrane receptors expressed by neurons. However, in contrast to glutamate and ATP for instance, the release of GABA by astrocytes is still poorly ...

• Excitatory neurons and astrocytes show marked alterations in the single‐cell spatial transcriptomic atlas of epileptogenic cortex from patients with focal cortical dysplasia type I (FCDI). • The CBLN2high excitatory neuron subtype may be associated with neuronal hyperexcitability and cortical development in FCDI.

About astroglia in the brain and pathology
More than 140 years astrocytes were described as passive cellularelements of the brain, and their function was limited participationin providing trophic potential of neurons.
