WebFeb 1, 2024 · Astrocytes, a non-neuronal glial cell type in the nervous system, are essential for regulating physiological functions of the central nervous system. In various injuries and diseases of the central nervous system, astrocytes often change their phenotypes into neurotoxic ones that participate in pro-inflammatory responses (hereafter referred to as … WebAug 21, 2024 · Like neurons, astrocytes originate from radial glial cells, which, despite their uniform appearance, form different progenitor domains within the ventricles of the developing brain, and generate cell subtypes with distinct morphological, functional and positional identities.
WebNew methods of labeling astrocytes, along with transgenic mice, allow the complete morphology of reactive astrocytes to be visualized. Recent studies show that reactivity can induce a remarkable change in the shape of a single astrocyte, that not all astrocytes react in the same way, and that there is plasticity in the reactive response.
Webexposure appears to alter astrocyte transcriptomes and morphology in various ways, leading to fewer processes and larger hypertrophied cell bodies akin to reactive astrocytes or fibroblasts . in vivo (Foo et al., 2011).
