BACKGROUND Neurotrophic factors, such as glial cell line-derived neurotrophic factor (GDNF), have shown great promise for protection and restoration of damaged or dying dopamine neurons in animal models and in some Parkinson's disease (PD) clinical trials. However, the delivery of neurotrophic factors to the brain is difficult due to their large size and poor bio-distribution. In addition, deve...
In vertebrates the development and function of the nervous system is regulated by neurotrophic factors (NTFs). Despite extensive searches no neurotrophic factors have been found in invertebrates. However, cell ablation studies in Drosophila suggest trophic interaction between neurons and glia. Here we report the invertebrate neurotrophic factor in Drosophila, DmMANF, homologous to mammalian MAN...
objective: to assess the effect of heparin binding neurotrophic factor (hbnf) on sciatic nerve regeneration in animal model of rat. methods: seventy-five male wistar rats were divided into five experimental groups randomly (each group containing 15 animals): sham operation group (sham), autograft group (auto), transected control (tc), chitosan conduit (chit) and heparin binding neurotrophic fac...
[Purpose] The aim of the present study was to investigate effects of skilled reach training with affected forelimb and treadmill exercise on the expression of neurotrophic factor following ischemia-induced brain injury in rats. [Subjects and Methods] Thirty male Sprague-Dawley rats were divided into 3 groups randomly: namely, the control sacrified 2 weeks after surgery, skilled reach training w...
The physiology of brain-derived neurotrophic factor signaling in enkephalinergic striatopallidal neurons is poorly understood. Changes in cortical Bdnf expression levels, and/or impairment in brain-derived neurotrophic factor anterograde transport induced by mutant huntingtin (mHdh) are believed to cause striatopallidal neuron vulnerability in early-stage Huntington's disease. Although several ...
Introduction: The prenatal stress is a key factor which affects the growth and function of the brain. Several studies have shown that prenatal stress induces deficits in learning and memory of the offspring. The prenatal stress alters the activity of neurotransmitters, such as noradrenaline, dopamine and serotonin, via over-activation of the hypothalamic–pituitary–adrenal axis. In addition, the...
Parkinson's disease (PD) is a degenerative disease of the central nervous system (CNS) predominantly occurring in older adults, and is particularly common after the age of 60. The primary pathologic characteristics of PD are neuronal degeneration and cell death of dopaminergic (DA-ergic) neurons, leading to a decrease in the dopamine (DA) level in the striatum. Originally extracted and purified...
Background/introduction Microbubbles (MBs) are small (1-5 μm diameter), perfluorcarbon gas filled lipid microspheres used for contrast enhancement during ultrasound imaging. MBs (Definity, others) are approved for contrast echocardiography and widely used (6 M patient injections) as ultrasound contrast agents with established pharmacokinetics and clearance data. Recent research has shifted to t...
This study determined the consequences of dopamine denervation of the striatum on synaptic plasticity and prevention of these changes with gene therapy using an adeno-associated viral vector (AAV) expressing glial cell line-derived neurotrophic factor (GDNF). C57BL6/J mice were injected with the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine(MPTP); long-term depression (LTD) or potenti...
