Two neurotrophic factors, brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3), are able to produce a long-lasting enhancement of synaptic transmission in the hippocampus. Unlike other forms of plasticity, neurotrophin-induced plasticity exhibited an immediate requirement for protein synthesis. Plasticity in rat hippocampal slices in which the(More)
The neurotrophin family of growth factors has received enormous attention recently for its role in modulating synaptic strength in the developing and adult nervous system. Several recent studies have indicated a role for brain-derived neurotrophic factor (BDNF) in long-term potentiation (LTP), a form of long-lasting plasticity observed at synapses in the(More)
The neurotrophins are signaling factors important for the differentiation and survival of distinct neuronal populations during development. To test whether the neurotrophins also function in the mature nervous system, the effects of brain-derived neurotrophic factor (BDNF), nerve growth factor (NGF), and neurotrophic factor 3 (NT-3) on the strength of(More)
The NGF-family of neurotrophic factors including NGF, BDNF and NT-3,4/5 is known to be crucial for neuronal survival and differentiation during development. However, recent studies suggest that the neurotrophins are also widely expressed and play a dynamic role in the mature nervous system. One of the major sites of expression of the neurotrophins in the(More)
The neurotrophins are a class of signaling molecules known for their growth and survival-promoting activities during neuronal development. Recent studies suggest that the neurotrophins, including brain-derived neurotrophic factor (BDNF), can also dramatically influence synaptic transmission in the adult hippocampus. The experiments described in this paper(More)
Upregulation of the lysosomal system has been suggested to contribute to the pathogenesis of Alzheimer's disease (AD). But the exact role of this system remains unknown. Okadaic acid (OA), a protein phosphatase-2A inhibitor, increases tau phosphorylation, β-amyloid deposition, and neuronal cell death, which are the pathological hallmarks of AD. To(More)
Recent studies have demonstrated the importance of neurotrophin function in adult synaptic plasticity. In an effort to characterize the intracellular signaling pathways that couple Trk receptor activation to the final physiological effects of neurotrophins, we have examined the role of intracellular calcium rises in neurotrophin-induced synaptic enhancement(More)
AIM Using diffusional kurtosis imaging (DKI) to assess the impact of emotional disorders on microstructural changes of the brain in children with haemophilia A. MATERIALS AND METHODS Diffusional kurtosis imaging was acquired from haemophilia A (n = 22) and controls (n = 22) using a 3T scanner. A regression analysis of frontal, cingulate, hippocampus,(More)
