Reactive astrocytes morphology
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 10, 2024 · Reactive astrocytes have specific morphological characteristics, such as increased cell volume, dendritic thickness, and number of processes [ 6 ]. Our previous study had reported that astrocytes are activated in the reactive state via the JAK/STAT3 pathway in 6-month-old 5XFAD mice [ 7 ].
