ProBDNF Collapses Neurite Outgrowth of Primary Neurons by Activating RhoA
BACKGROUND Neurons extend their dendrites and axons to build functional neural circuits, which are regulated by both positive and negative signals during development. Brain-derived neurotrophic factor (BDNF) is a positive regulator for neurite outgrowth and neuronal survival but the functions of its precursor (proBDNF) are less characterized. METHODOLOGY/PRINCIPAL FINDINGS Here we show that p...
متن کاملNeurotrophic factor for central neurons.
A serum-free culture of dissociated neurons from embryonic rat hippocampus has been established as a rapid and quantitative in vitro test system for neurotrophic signals in the mammalian brain. By means of this cell culture bioassay, a novel low molecular weight neurotrophic factor (NTF) could be identified. NTF is essential for in vitro brain neuron development, promoting survival and neurite ...
متن کاملImmobilized concentration gradients of neurotrophic factors guide neurite outgrowth of primary neurons in macroporous scaffolds.
Neurotrophic factors present as concentration gradients are neurotropic cues that direct axonal growth toward their targets. Multiple factors work together in vivo to ensure axons reach the proper targets, likely interacting with one another via intracellular signalling pathways. Nerve growth factor (NGF) and neurotrophin-3 (NT-3) are neurotrophins known to guide axons as well as promote axonal...
متن کاملOverexpression of ciliary neurotrophic factor in vivo rescues chick ciliary ganglion neurons from cell death.
Ciliary ganglion (CG) neurons undergo target-dependent cell death during embryonic development. Although ciliary neurotrophic factor (CNTF) was identified in vitro by its ability to support the survival of chick CG neurons, its function as a target-derived neurotrophic factor has been questioned by those working on mammalian-derived forms of CNTF. We have purified and cloned a chicken CNTF [chC...
متن کاملTumor necrosis factor inhibits neurite outgrowth and branching of hippocampal neurons by a rho-dependent mechanism.
In response to injury and inflammation of the CNS, brain cells including microglia and astrocytes secrete tumor necrosis factor-alpha (TNF). This pro-inflammatory cytokine has been implicated in both neuronal cell death and survival. We now provide evidence that TNF affects the formation of neurites. Neurons cultured on astrocytic glial cells exhibited reduced outgrowth and branching of neurite...
