Axonal target-derived BMP and neurotrophin signaling are both known to regulate neuronal gene expression, differentiation, and axon growth. In this issue of Neuron, Ji and Jaffrey (2012) discovered that BMP-signaling endosomes depend on BDNF-induced axonal synthesis of SMADs to retrogradely regulate transcription in developing trigeminal neurons, providing a mechanism of integrating the two tar...

During development, newly born neurons migrate away from their initial birth sites to their final positions in the mature brain. The neurotrophin BDNF has been shown to regulate the migration of granule cells in the cerebellum. The cellular mechanisms that mediate this chemotactic response have not been resolved. In this issue of Neuron, Zhou et al. show that vesicle trafficking is critical for...

Objective(s): Neurotrophic factors secreting cells (NTS-SCs) may be a superior cell source for cell-based therapy in neurodegenerative diseases. NTS-SCs are able to secrete some neurotrophic Such as nerve growth factor and glia-derived neurotrophic factor. Our primary aim was to assess transplantation of neurotrophic factor secreting cells derived from human adipose-derived stem cells (hADSCs) ...

Glial cell line-derived neurotrophic factor (GDNF) has been shown to rescue developing motoneurons in vivo and in vitro from both naturally occurring and axotomy-induced cell death. To test whether GDNF has trophic effects on adult motoneurons, we used a mouse model of injury-induced adult motoneuron degeneration. Injuring adult motoneuron axons at the exit point of the nerve from the spinal co...

Staurosporine (STS), a broad spectrum protein kinase inhibitor, was previously shown to induce neurite outgrowth in several neuroblastoma cell lines. However, data on the neurotrophic potential of this alkaloid in embryonic stem cell systems were not available. Therefore, three mouse ES cell lines, IB10, RW4, and Bruce 4, were induced to enter neurogenesis in culture at low concentrations of ST...

A surface marker that distinctly identifies cardiac progenitors (CPs) is essential for the robust isolation of these cells, circumventing the necessity of genetic modification. Here, we demonstrate that a Glycosylphosphatidylinositol-anchor containing neurotrophic factor receptor, Glial cell line-derived neurotrophic factor receptor alpha 2 (Gfra2), specifically marks CPs. GFRA2 expression faci...

Glial cell line-derived neurotrophic factor is one of the most potent motoneuron survival factors yet identified. Although retrograde transport of trophic factors to the cell body is thought to be an important process in motoneuron survival, the transport pathways that lead to interaction of glial cell line-derived neurotrophic factor with its receptors is not known. We have used a double ligat...

Here, we describe the generation of viable and dopamine-producing neurons derived from pluripotent mouse embryonic stem cells. Neurotrophic factors in combination with survival-promoting factors, such as interleukin-1beta, glial cell line-derived neurotrophic factor, neurturin, transforming growth factor-beta(3) and dibutyryl-cyclic AMP, significantly enhanced Nurr1 and tyrosine hydroxylase (TH...

Citrus kawachiensis (Kawachi Bankan), is a citrus species grown in Ehime, Japan, and its peel abundant 3,5,6,7,8,3′,4′-heptamethoxyflavone (HMF). We have recently revealed that HMF, one of the flavonoids, has anti-inflammatory activity neuroprotective abilities brain against global cerebral ischemia. HMF rescued neuronal cell death hippocampus suppressed activation microglia, whose been shown t...
