Stroke incidence increases with age and this has been attributed to vascular factors. We show here that CNS white matter (WM) is intrinsically more vulnerable to ischemic injury in older animals and that the mechanisms of WM injury change as a function of age. The mouse optic nerve was used to study WM function. WM function in older animals (12 months) was(More)
The neurovascular unit is an emerging concept that emphasizes homeostatic interactions between endothelium and cerebral parenchyma. Here, we show that cerebral endothelium are not just inert tubes for delivering blood, but they also secrete trophic factors that can be directly neuroprotective. Conditioned media from cerebral endothelial cells broadly(More)
The glutamate receptor was one of the most intensely investigated targets for neuroprotection. However, numerous clinical trials of glutamate receptor antagonists for the treatment of stroke were unsuccessful. These failures have led to pessimism in the field. But recent advances could provide hope for the future. This minireview looks beyond the(More)
Neuregulin-1 (NRG1) signaling has multiple functions in neurons and glia. The data in this study show that NRG1 may also possess significant signaling and cytoprotective properties in human brain microvascular endothelial cells (BMECs). Neuregulin-1 mRNA and protein expression are present in these cells, and NRG1 receptors erbB2 and erbB3 are phosphorylated(More)
