WebReactive astrogliosis, whereby astrocytes undergo varying molecular and morphological changes, is a ubiquitous but poorly understood hallmark of all central nervous system pathologies. Now genetic tools are enabling the molecular dissection of the functions and mechanisms of reactive astrogliosis in vivo. WebHSP27/Aβ interactions also take place in reactive astrocytes. For example, primary rat astrocytes release HSP27 in response to Aβ exposure , and HSP27 immunoreactive cells of astrocytic morphology were observed in AD brain tissue . Thus, our data on astrocytic HSP27 expression reported here for human AD and APP-transgenic mouse brain tissue ...
WebFeb 1, 2015 · Reactive astrogliosis is a characteristic change in the morphology and function of astrocytes seen in many neurological disorders, such as neurotrauma, ischemic stroke, and neurodegenerative disease, which profoundly affects both the disease progression and the recovery process [ 20, 21••, 22 ]. WebJul 6, 2024 · Putative astrocyte morphology ranged from resting (Fig. 1A; cortex, control, inset) to reactive, featuring somatic hypertrophy and thick processes (Fig. 1A; thalamus and cortex, stroke, inset). These changes were evident both acutely and years after stroke or TBI and were supported by a semiquantitative analysis of GFAP immunoreactivity (table S2).
