Activation of Egr-1 expression in astrocytes by HIV-1 Tat: new insights into astrocyte-mediated Tat neurotoxicity [PDF]

open access: yes, 2011
Human immunodeficiency virus type 1 (HIV-1) Tat plays an important role in HIV-associated neuropathogenesis; the underlying mechanisms are still evolving. We have recently shown that HIV-1 Tat induces expression of glial fibrillary acidic protein (GFAP),

Astrocytes: a double-edged sword in neurodegenerative diseases

open access: yesNeural Regeneration Research, 2021
Astrocytes play multifaceted and vital roles in maintaining neurophysiological function of the central nervous system by regulating homeostasis, increasing synaptic plasticity, and sustaining neuroprotective effects.

Active sulforhodamine 101 uptake into hippocampal astrocytes. [PDF]

open access: yesPLoS ONE, 2012
Sulforhodamine 101 (SR101) is widely used as a marker of astrocytes. In this study we investigated labeling of astrocytes by SR101 in acute slices from the ventrolateral medulla and the hippocampus of transgenic mice expressing EGFP under the control of ...

Astrocytic LRP1 mediates brain Aβ clearance and impacts amyloid deposition [PDF]

open access: yes, 2017
Accumulation and deposition of amyloid-β (Aβ) in the brain represent an early and perhaps necessary step in the pathogenesis of Alzheimer's disease (AD).

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.

Demonstration of astrocytes in cultured amniotic fluid cells of three cases with neural-tube defect [PDF]

open access: yes, 1981
We have investigated the origin of rapidly adhering (RA) cells in three cases of neural tube defects (two anencephali, one encephalocele). We were able to demonstrate the presence of glial fibrillary acidic (GFA) protein in variable percentages (4–80 ...

Crosstalk Between Astrocytes and Microglia: An Overview

open access: yesFrontiers in Immunology, 2020
Based on discoveries enabled by new technologies and analysis using novel computational tools, neuroscience can be re-conceived in terms of information exchange in dense networks of intercellular connections rather than in the context of individual ...

Protective astrogenesis from the SVZ niche after injury is controlled by Notch modulator Thbs4. [PDF]

open access: yes, 2013
Postnatal/adult neural stem cells (NSCs) within the rodent subventricular zone (SVZ; also called subependymal zone) generate doublecortin (Dcx)(+) neuroblasts that migrate and integrate into olfactory bulb circuitry.

Astrocytes Maintain Glutamate Homeostasis in the CNS by Controlling the Balance between Glutamate Uptake and Release

open access: yesCells, 2019
Glutamate is one of the most prevalent neurotransmitters released by excitatory neurons in the central nervous system (CNS); however, residual glutamate in the extracellular space is, potentially, neurotoxic.

Fast Generation of Functional Subtype Astrocytes from Human Pluripotent Stem Cells

open access: yesStem Cell Reports, 2018
Summary: Differentiation of astrocytes from human pluripotent stem cells (hPSCs) is a tedious and variable process. This hampers the study of hPSC-generated astrocytes in disease processes and drug development.
