Connexins in Astrocyte Migration
(Frontiers Media, 2020)
Astrocytes have long been considered the supportive cells of the central nervous system, but during the last decades, they have gained much more attention because of their active participation in the modulation of neuronal ...
Key Role of Astrocytes in Postnatal Brain and Retinal Angiogenesis
(2022)
Angiogenesis is a key process in various physiological and pathological conditions in the nervous system and in the retina during postnatal life. Although an increasing number of studies have addressed the role of endothelial ...
Signaling pathways involved in neuron-astrocyte adhesion and migration
(2014)
Astrocytes in the normal brain possess a stellate shape reflecting their non-migratory properties. Alternatively, in neurodegenerative diseases or after injury, astrocytes become "reactive" in a process known as astrocytosis ...
Connexins in Astrocyte Migration
(2020)
Astrocytes have long been considered the supportive cells of the central nervous system, but during the last decades, they have gained much more attention because of their active participation in the modulation of neuronal ...
Control of astrocytic Ca2+ signaling by nitric oxide-dependent S-nitrosylation of Ca2+ homeostasis modulator 1 channels
(2024)
Background Astrocytes Ca2+ signaling play a central role in the modulation of neuronal function. Activation of metabotropic glutamate receptors (mGluR) by glutamate released during an increase in synaptic activity triggers ...
An outside-in switch in integrin signaling caused by chemical and mechanical signals in reactive astrocytes
(Frontiers Media, 2021)
Astrocyte reactivity is associated with poor repair capacity after injury to the brain, where chemical and physical changes occur in the damaged zone. Astrocyte surface proteins, such as integrins, are upregulated, and the ...
Reactive oxygen species released from astrocytes treated with amyloid beta oligomers elicit neuronal calcium signals that decrease phospho-Ser727-STAT3 nuclear content
(Elsevier, 2018)
The transcription factor STAT3 has a crucial role in the development and maintenance of the nervous system. In this work, we treated astrocytes with oligomers of the amyloid beta peptide (A beta Os), which display potent ...
Production of nerve growth factor by β-amyloid-stimulated astrocytes induces p75NTR-dependent tau hyperphosphorylation in cultured hippocampal neurons
(2006)
Reactive astrocytes surround amyloid depositions and degenerating neurons in Alzheimer's disease (AD). It has been previously shown that β-amyloid peptide induces inflammatory-like responses in astrocytes, leading to ...
Astrocytes and human cognition: Modeling information integration and modulation of neuronal activity
(Pergamon-Elsevier B.V. Ltd, 2010-11-01)
Recent research focusing on the participation of astrocytes in glutamatergic tripartite synapses has revealed mechanisms that support cognitive functions common to human and other mammalian species, such as learning, ...
