WebJan 25, 2024 · Reactive astrocytes are now widely regarded as critical players in the pathophysiology of CNS diseases. Together with neurons and other glial cells, reactive astrocytes sustain neuroinflammation and dictate the outcome, either toward recovery and resolution of the injury or toward permanent damage and disease progression ( 15 ). 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 ...
