Abstract Introduction Cochlear implants (CIs) utilising eluting electrodes are a relatively new phenomenon. CI surgery can lead to variety of complications, namely electrode insertion trauma. This affects function leading loss residual hearing. To minimise this, anti-inflammatory or growth-promoting agents be used protect and enhance hearing through the sustained release an agent. Eluting inclu...

Neurotrophins regulate growth, survival, and differentiation of central neurons. In addition to the "classical" effects that are relatively slow neurotrophins also elicit rapid signaling that modulates a variety of cellular functions such as membrane excitability, synaptic transmission, and activity-dependent synaptic plasticity. These rapid actions are mediated mainly through the interaction o...

The neurotrophins brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), and neurotrophin-4/5 (NT-4/5) were compared for their effects in promoting the survival and/or regulation of expression of phenotypic markers of dopaminergic and GABAergic neurons in cultures derived from embryonic rat ventral mesencephalon. Dopaminergic neuron number and phenotypic expression were monitored by t...

Adult facial motor neurons continue to express full-length TrkB tyrosine kinase receptor (TrkB.FL), the high-affinity receptor for the neurotrophins BDNF and neurotrophic factor-4/5 (NT-4/5), suggesting that they remain dependent on target-derived and locally produced neurotrophins in adulthood. Studies on the role of TrkB signaling in the adult CNS have been hampered by the early lethality of ...

Neurotrophins are a family of closely related proteins that were identified initially as survival factors for sensory and sympathetic neurons, and have since been shown to control many aspects of survival, development and function of neurons in both the peripheral and the central nervous systems. Each of the four mammalian neurotrophins has been shown to activate one or more of the three member...

The developing cerebral cortex undergoes overlapping periods of neurogenesis, suicide, and differentiation to generate the mature cortical plate. The following experiments examined the role of the gonadal hormone estrogen in comparison to the neurotrophins, in the regulation of p53-dependent cortical cell fate. To synchronize choices between neurogenesis, apoptosis, and neural differentiation, ...

Background: Complex regional pain syndrome (CRPS) is a rare painful condition that usually appears after trauma or surgery of the extremities. Symptoms include pain, sensory, sudomotor and vasomotor disturbances, trophic changes impaired motor function. The course varies from mild to chronic disease with high impact on daily functioning quality life. In skin tissue, sustained inflammatory, fibr...

objective(s): neurotrophins (nts) exert various effects on neuronal system. growing evidence indicates that nts are involved in the pathophysiology of neuropathic pain. however, the exact role of these proteins in modulating nociceptive signaling requires being defined. thus, the aim of this study was to evaluate the effects of spinal nerve ligation (snl) on nts activation in the lumbar dorsal ...

The distribution of the neurotrophins BDNF and NT-3 as well as their corresponding high-affinity receptors trkB and trkC was characterized by immunohis-tochemistry in the developing retino-tectal system of the pigeon. These neurotrophins are known to be important for survival and development of neuronal tissues, but also for activity-dependent neuronal plasticity. In pigeons visual asymmetry is...

Wallerian degeneration is a complicated process whereby axons and myelin sheaths undergo degeneration, and eventually are phagocytosed by macrophages and Schwann cells following nerve damage. Schwann cells proliferate and the endoneural tubes persist. In addition, neurotrophins, neural cell adhesion molecules, cytokines and other soluble factors are upregulated to facilitate regeneration. The i...
