Astrocyte dysfunction in Alzheimer disease.

abstract：:Although they likely involve activation of N-methyl-D-aspartate (NMDA) receptors, the mechanisms giving rise to perinatal hypoxic-ischemic-induced damages remained unclear. The purpose of the present study was to investigate in vivo the mechanisms regulating the glutamate-induced release of toxic hydroxyl radicals (.O...

abstract：:Apolipoprotein E (apo-E), a protein involved in lipid metabolism and cholesterol transport, has been found to be up-regulated in CNS injury and is associated with Alzheimer's disease in humans. In this study, we show that apo-E is also up-regulated after complete spinal cord transection in the C57BL/6 mouse. In the un...
