Reactive gliosis definition
WebGliosis, also called astrocytic gliosis or astrocytosis, is a common term that refers to the reactive astrocytic response to a brain injury or insult. Almost all brain lesions have a component of gliosis, even with different glial pathologies. Gliosis is a secondary event to CNS damage and may persist for weeks or months after brain injury. WebGliosis, including the activation and often proliferation of glial cells, is a non-specific phenomenon observed in neuro-degenerative diseases and brain injury. There is increasing recognition that reactive astrocytes are vital and central responders to CNS injury and disease, but there is no widely accepted definition of reactive astrogliosis.
