The neurotrophins comprise a family of secreted proteins that elicit profound responses in cells of the developing and mature vertebrate nervous system including the regulation of neuronal survival and differentiation. The molecular mechanisms by which the neurotrophins exert their effects have been the subject of intense investigation. The neurotrophins elicit responses in neurons via members ...
The proteins of the mammalian neurotrophin family (nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3) and neurotrophin-4/5 (NT-4/5)) were originally identified as neuronal survival factors. During the last decade, evidence has accumulated implicating them (especially BDNF) in addition in the regulation of synaptic transmission and synaptogenesis in the CN...
The interaction of the neurotrophin BDNF dipeptide mimetic, compound GSB-106, with tyrosine kinase TrkB receptor specific for fullsized was studied using surface plasmon resonance. significant decrease in binding to TrkB, which preincubated shown. obtained data indicate GSB-106 receptor.
Background: Adipose tissue stem cells (ASCs) cause faster repair of damaged tissue posttransplantation by releasing growth factors in neurodegenerative diseases. ASCs secrete factors in the culture medium called conditioned medium (CM) in vitro. This study investigated the expression of neurotrophin genes in vitro culture and transplant of ASCs in Parkinsonian rats. Materials and Methods: In th...
The p75 neurotrophin receptor is important in multiple physiological actions including neuronal survival and neurite outgrowth during development, and after central nervous system injury. We have discovered a novel piperazine-derived compound, EVT901, which interferes with p75 neurotrophin receptor oligomerization through direct interaction with the first cysteine-rich domain of the extracellul...
Neuronal activity, hormones, transmitters, physical exercise and enrichment influence cortical neurotrophin expression. Neurotrophins then elicit structural and physiological changes, and regulate gene expression. This prompted the hypothesis that neurotrophins themselves are involved in regulating neurotrophin expression. Here we investigated the mRNA expression level of brain-derived neurotro...
Expression of the neurotrophin-3 receptor, tyrosine kinase C (TrkC), is associated with favorable prognosis in medulloblastoma patients. This may be due to increased tumor apoptosis induced by TrkC activation. Neurotrophin-3/TrkC-induced apoptosis is inhibited by the mitogen-activated protein (MAP) kinase (MAPK) pharmacologic antagonists SB203580 and PD98059. In addition to extracellular signal...
introduction: neurotrophins belong to growth factor family and their function is based on their receptors. they bind two types of receptors: p75 and tyrosine kinase. the motoneuron survival or death depends upon the neurotrophic factors. recent studies have demonstrated that axotomy in peripheral nerve induces apoptosis of motoneuron. deprenyl or selegiline is known as a drug with neuroprotecti...
During development and nerve injury, complex interactions between glial cells and neurons are essential for establishing proper nerve function. Neurotrophins play multiple roles in the developing nervous system, including cell survival, growth, and differentiation. Here we show that migration of Schwann cells, isolated from sciatic nerves, is significantly enhanced by neurotrophin 3, but not by...
