WebSep 1, 2024 · A1/A2 astrocytes and their specific markers are closely related to various CNS injuries and diseases. A1/A2 astrocytes have diverse effects on the neurovascular unit in CNS injuries and diseases. The local extracellular and intracellular signals regulate phenotypic switch of astrocytes. WebAstrocytes respond to changes in brain homoeostasis following central nervous system (CNS) injury/diseased state by a specific defence mechanism called reactive astrogliosis. Recent studies have implicated and placed reactive astrogliosis in the centre of pathophysiology of Alzheimer's disease (AD) and other neurodegenerative disorders.
