Neurotrophic factors (NTF) play key roles in the survival of neurons, making them promising candidates for therapy neurodegenerative diseases. In case inner ear, sensorineural hearing loss (SNHL) is characterized over time by a degeneration primary auditory spiral ganglion neurons (SGN). It well known that selected NTF can protect SGN from degeneration, which positively influences outcome cochl...

objective(s): the present study aims to study the alteration of glutamatergic transmission in the dorsal horn neurons and the effect of gabapentin on oxaliplatin-induced neuropathic pain in rats. materials and methods: oxaliplatin (5 mg/kg) or saline was administered to adult male sprague-dawley rats.  gabapentin (60 mg/kg, ip) or vehicle was injected daily. mechanical allodynia was assessed us...

The intraneuronal accumulation of the microtubule associated protein tau in a hyperphosphorylated state and the extracellular deposit of ßamyloid protein constitute the defining neuropathological signature of Alzheimer's disease, the most common type of dementia in ageing Homo sapiens.There is accumulating evidence suggesting that transplantation of embryonic and adult derived neuronal precurso...

Neural stem cells (NSCs) offer the potential to replace lost tissue after nervous system injury. This study investigated whether grafts of NSCs (mouse clone C17.2) could also specifically support host axonal regeneration after spinal cord injury and sought to identify mechanisms underlying such growth. In vitro, prior to grafting, C17.2 NSCs were found for the first time to naturally constituti...

This article reviews recent studies that have examined differences and similarities in the neurotrophic growth factor requirements of neural crest- and neural placode-derived sensory neurons of the developing chick embryo. From in vitro experiments using both explant and dissociated, neuron-enriched cultures of spinal and cranial nerve sensory neurons, it has been established that only sensory ...

Axonal maintenance, plasticity, and regeneration are influenced by signals from neighboring cells, in particular Schwann cells of the peripheral nervous system. Schwann cells produce neurotrophic factors, but the mechanisms by which ciliary neurotrophic factor (CNTF) and other neurotrophic molecules modify the axonal cytoskeleton are not well understood. In this paper, we show that activated si...

Ciliary neurotrophic factor was discovered based on its ability to support the survival of ciliary neurons, and is now known to act on a variety of neuronal and glial populations. Two distant relatives of ciliary neurotrophic factor, leukemia inhibitory factor and oncostatin M, mimic ciliary neurotrophic factor with respect to its actions on cells of the nervous system. In contrast to ciliary n...
