The aim is to investigate the effect of neuregulin-1beta (NRG-1beta) on the neuronal apoptosis and the expressions of signal transducer and activator of transcription (STAT3) and glial fibrillary acidic protein (GFAP) in rats following cerebral ischemia/reperfusion. The animal models of middle cerebral artery occlusion/reperfusion (MCAO/R) were established(More)
Oxidative stress is one of the most important pathological mechanisms in neurodegenerative diseases and ischemia. Recent studies have indicated that the sonic hedgehog (SHH) signaling pathway is involved in these diseases, but the underlying mechanisms remains elusive. Here we report that the SHH pathway was activated in primary cultured cortical neurons(More)
The human adult brain possesses intriguing plasticity, including neurogenesis and angiogenesis, which may be mediated by the activated sonic hedgehog (Shh). By employing a coculture system, brain microvascular endothelial cells (BMECs) cocultured with astrocytes, which were incubated under oxygen–glucose deprivation (OGD) condition, we tested the hypothesis(More)
The aim is to investigate the effects of neuregulin-1beta (NRG-1beta) on expression of matrix metalloproteinase-9 (MMP-9) and neuron-specific enolase (NSE) in brain tissue in rats following cerebral ischemia/reperfusion. One hundred and fifty adult healthy male Wistar rats were used in the present study. Ten of them were randomized into a sham-operation(More)
In this study, we tried to explore the molecular mechanism that Corilagin protected against herpes simplex virus-1 encephalitis through inhibiting the TLR2 signaling pathways in vivo and in vitro. As a result, Corilagin significantly prevented increase in the levels of TLR2 and its downstream mediators following Malp2 or HSV-1 challenge. On the other hand,(More)
BACKGROUND AND PURPOSE The prognosis of herpes simplex encephalitis (HSE) remains poor despite available antiviral treatment. Matrix metalloproteinase-9 (MMP-9) is currently considered to play a major role in promoting cerebrovascular complications which contribute to the high mortality and morbidity of HSE. We hypothesize that temporally knockdown MMP-9(More)
BACKGROUND AND PURPOSE Herpes simplex encephalitis remains one of the most devastating intracranial infections despite available antiviral treatment, with sequelae secondary to a persistent inflammatory response. Recently, cyclin-dependent kinases (CDKs) have been found to act as cellular targets for antiviral drugs. However, the pharmacological effects of(More)
The nutrient transportation ability of placenta depends on placental size, vascular density and permeability. Regulation of angiogenesis in the placenta is critical for successful gestation. Placenta vascularity exhibits disparity in different gestation stages and different pig breeds. To investigate the expression of genes related to permeability in the(More)
Passive movement has been found to improve evidently ischemic stroke patients’ impaired capacity of learning and memory, but the optimal time window of initiating the therapy and the underlying mechanism are not fully understood. In this study, the effect of passive movement at different time windows on learning and memory of rats with cerebral infarction(More)
OBJECTIVE To evaluate the effects of transcranial magnetic stimulation (TMS) on the brain plasticity and its role in functional outcome in cerebral infarction. METHODS Twenty male SD rats underwent suture of the unilateral middle cerebral artery (MCA) so as to establish focal cerebral infarction models and then were randomly divided into 2 equal groups:(More)
