Neuregulin-1 (NRG-1) is a growth factor with potent neuroprotective capacity in ischemic stroke. We recently showed that NRG-1 reduced neuronal death following transient middle cerebral artery occlusion (tMCAO) by up to 90% with an extended therapeutic window. Here, we examined the neuroprotective potential of NRG-1 using a permanent MCAO ischemia (pMCAO)(More)
We previously showed that neuregulin-1 (NRG-1) protected neurons from death in vivo following focal ischemia. The goal of this study was to develop an in vitro rat ischemia model to examine the cellular and molecular mechanisms involved in the neuroprotective effects of NRG-1 on ischemia-induced neuronal death. Rat B-35 neuroblastoma cells differentiated by(More)
We have previously shown that neuregulin-1 (NRG-1) protects neurons from ischemic brain injury if administered before focal stroke. Here, we examined the therapeutic window and functional recovery after NRG-1 treatment in rats subjected to 90 mins of middle cerebral artery occlusion (MCAO) and 24 h of reperfusion. Neuregulin-1 (2.5 microg/kg [corrected](More)
Neuregulins are a family of growth factors with potent neuroprotective properties. We recently demonstrated that neuregulin-1 blocked delayed neuronal death following focal ischemic stroke in the rat. Focal ischemia results in the release of pro-inflammatory cytokines that produce profound changes in gene expression and contribute to cell death associated(More)
