Chondroitin sulfate (CS) is a major microenvironmental molecule in the CNS, and there have been few reports about its neuroprotective activity. As neuronal cell death by excitotoxicity is a crucial phase in many neuronal diseases, we examined the effect of various CS preparations on neuronal cell death induced by the excitotoxicity of glutamate analogs. CS(More)
Chondroitin sulfate proteoglycans have been shown to participate in the pathogenesis of neuronal damages in the injured adult central nervous system (CNS). Upregulated expression of chondroitin sulfate proteoglycans has been reported around the injured sites and depletion of these chondroitin sulfate proteoglycans brings about increased axonal regeneration(More)
Perinatal hypoxia-ischemia (HI) remains a critical issue. Cell transplantation therapy could be a potent treatment for many neurodegenerative diseases, but limited works on this kind of therapy have been reported for perinatal HI. In this study, the therapeutic effect of transplantation with neural stem/ progenitor cells (NSPCs) and chondrotinase ABC(More)
Hypoxia-ischemia is a common cause of neonatal brain injuries. Nitric oxide (NO) is upregulated in the brain after hypoxia-ischemia and generally believed to exert a paradoxical effect on neurons, neurodestruction and neuroprotection, but it has not been demonstrated that NO is actually neuroprotective in neonatal hypoxic-ischemic encephalopathy.
