Astrocyte morphology

Trends in Cell Biology
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 such complex morphological shapes evolved to allow astrocytes to contact and signal with diverse ...

Activation and Role of Astrocytes in Ischemic Stroke

Frontiers in Cellular Neuroscience, 2021
Ischemic stroke refers to the disorder of blood supply of local brain tissue caused by various reasons. It has high morbidity and mortality worldwide. Astrocytes are the most abundant glial cells in the central nervous system (CNS).

CCAAT/enhancer binding protein β expression is increased in the brain during HIV-1-infection and contributes to regulation of astrocyte tissue inhibitor of metalloproteinase-1 [PDF]

, 2011
Human immunodeficiency virus (HIV)-1-associated neurocognitive disorders (HAND) associated with infection and activation of mononuclear phagocytes (MP) in the brain, occur late in disease. Infected/activated MP initiate neuroinflammation activating glial

Transfer of mitochondria from astrocytes to neurons after stroke

Nature, 2016
Neurons can release damaged mitochondria and transfer them to astrocytes for disposal and recycling. This ability to exchange mitochondria may represent a potential mode of cell-to-cell signalling in the central nervous system.

Blocking microglial activation of reactive astrocytes is neuroprotective in models of Alzheimer’s disease

Acta Neuropathologica Communications, 2021
Alzheimer’s disease (AD) is the most common cause of age-related dementia. Increasing evidence suggests that neuroinflammation mediated by microglia and astrocytes contributes to disease progression and severity in AD and other neurodegenerative ...

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

Molecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.

Intracellular deposits of amyloid-beta influence the ability of human iPSC-derived astrocytes to support neuronal function

Journal of Neuroinflammation, 2023
Background Astrocytes are crucial for maintaining brain homeostasis and synaptic function, but are also tightly connected to the pathogenesis of Alzheimer’s disease (AD).

Widespread Decrease of Cerebral Vimentin-Immunoreactive Astrocytes in Depressed Suicides

Frontiers in Psychiatry, 2021
Post-mortem investigations have implicated cerebral astrocytes immunoreactive (-IR) for glial fibrillary acidic protein (GFAP) in the etiopathology of depression and suicide.

The effect of spatial learning on the number of astrocytes in rat dentate gyrus [PDF]

, 2007
In this study, we evaluated the effect of spatial learning on the number of astrocytes in the rat dentate gyrus with Morris water maze. Fifteen male albino Wistar rats were divided into three groups as control, reference memory and working memory groups.
