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,(More)
A brief period of global brain ischemia, such as that induced by cardiac arrest or cardiopulmonary bypass surgery, causes cell death in vulnerable hippocampal CA1 pyramidal neurons days after reperfusion. Although numerous factors have been suggested to account for this phenomenon, the mechanisms underlying it are poorly understood. We describe a cell death(More)
