Essential protective roles of reactive astrocytes in traumatic brain injury.
Astrocytes respond to traumatic brain injury (TBI) by altered gene expression, hypertrophy and proliferation that occur in a gradated fashion in relation to the severity of the injury. Both beneficial and detrimental effects have been attributed to reactive astrocytes, but their roles after brain injury are not well understood. To investigate these roles, we determined the effects on cortical t...
متن کاملOpposing roles for reactive astrocytes following traumatic brain injury.
Traumatic brain injury (TBI) is a leading cause of death and disability in the United States. Current medical therapies exhibit limited efficacy in reducing neurological injury and the prognosis for patients remains poor. While most research is focused on the direct protection of neuronal cells, non-neuronal cells, such as astrocytes, may exert an active role in the pathogenesis of TBI. Astrocy...
متن کاملProtective role of reactive astrocytes in brain ischemia.
Reactive astrocytes are thought to protect the penumbra during brain ischemia, but direct evidence has been lacking due to the absence of suitable experimental models. Previously, we generated mice deficient in two intermediate filament (IF) proteins, glial fibrillary acidic protein (GFAP) and vimentin, whose upregulation is the hallmark of reactive astrocytes. GFAP(-/-)Vim(-/-) mice exhibit at...
