MeCP2 Deficiency Leads to Loss of Glial Kir4.1 [PDF]

open access: yeseneuro, 2018
AbstractRett syndrome (RTT) is an X-linked neurodevelopmental disorder usually caused by mutations in methyl-CpG-binding protein 2 (MeCP2). RTT is typified by apparently normal development until 6–18 mo of age, when motor and communicative skills regress and hand stereotypies, autonomic symptoms, and seizures present.

Review: Dystroglycan in the Nervous System [PDF]

open access: yes, 2007
Dystroglycan is part of a large complex of proteins, the dystrophin-glycoprotein complex, which has been implicated in the pathogenesis of muscular dystrophies for a long time.

Inhibition of Inwardly Rectifying Potassium (Kir) 4.1 Channels Facilitates Brain-Derived Neurotrophic Factor (BDNF) Expression in Astrocytes

open access: yesFrontiers in Molecular Neuroscience, 2017
Inwardly rectifying potassium (Kir) 4.1 channels in astrocytes regulate neuronal excitability by mediating spatial potassium buffering. Although dysfunction of astrocytic Kir4.1 channels is implicated in the development of epileptic seizures, the ...

Role of collecting duct principal cell NOS1β in sodium and potassium homeostasis

open access: yesPhysiological Reports, 2021
The nitric oxide (NO)‐generating enzyme, NO synthase‐1β (NOS1β), is essential for sodium (Na+) homeostasis and blood pressure control. We previously showed that collecting duct principal cell NOS1β is critical for inhibition of the epithelial sodium ...

The ribosome-associated protein RACK1 represses Kir4.1 translation in astrocytes and influences neuronal activity

open access: yesCell Reports, 2023
Summary: The regulation of translation in astrocytes, the main glial cells in the brain, remains poorly characterized. We developed a high-throughput proteomics screen for polysome-associated proteins in astrocytes and focused on ribosomal protein ...

Expressional analysis of the astrocytic Kir4.1 channel in a pilocarpine-induced temporal lobe epilepsy model

open access: yesFrontiers in Cellular Neuroscience, 2013
The inwardly-rectifying potassium (Kir) channel Kir4.1 in brain astrocytes mediates spatial K+ buffering and regulates neural activities. Recent studies have shown that loss-of-function mutations in the human gene KCNJ10 encoding Kir4.1 cause epileptic ...

Genetic deletion of laminin isoforms β2 and γ3 induces a reduction in Kir4.1 and aquaporin-4 expression and function in the retina. [PDF]

open access: yesPLoS ONE, 2011
Glial cells such as retinal Müller glial cells are involved in potassium ion and water homeostasis of the neural tissue. In these cells, inwardly rectifying potassium (Kir) channels and aquaporin-4 water channels play an important role in the process of ...

Oligodendrocytes control potassium accumulation in white matter and seizure susceptibility

open access: yeseLife, 2018
The inwardly rectifying K+ channel Kir4.1 is broadly expressed by CNS glia and deficits in Kir4.1 lead to seizures and myelin vacuolization. However, the role of oligodendrocyte Kir4.1 channels in controlling myelination and K+ clearance in white matter ...

Aquaporin-4-dependent K(+) and water transport modeled in brain extracellular space following neuroexcitation. [PDF]

open access: yes, 2013
Potassium (K(+)) ions released into brain extracellular space (ECS) during neuroexcitation are efficiently taken up by astrocytes. Deletion of astrocyte water channel aquaporin-4 (AQP4) in mice alters neuroexcitation by reducing ECS [K(+)] accumulation ...

Astrocyte Regulation of Spinal Circuit Function. [PDF]

open access: yesJ Neurochem
Spinal cord astrocytes exist as an additional component of the computational framework that governs both sensory perceptions and motor outputs (left). By integrating local synaptic activity together with signals that reflect whole‐body state (e.g., neuromodulators, immune signals, and vascular signals) into defined input states (Sn), astrocytes adapt ...
