In dissociated cultures of SCN, glutamate caused a rapid (15 min) induction of nuclear pCREB-ir and Fos-ir (after 60 min) exclusively in neurones, both GABA-ir and others.

Glutamatergic induction of nuclear pCREB-ir in GABA-ir neurones was blocked by KN-62 an inhibitor of Ca2+/Calmodulin (CaM)-dependent kinases, implicating Ca2+-dependent signalling pathways in the glutamatergic regulation of gene expression in the SCN.

It is unclear, however, whether KA-induced mossy fiber sprouting results from neuronal cell loss or the seizure activity that KA induces.

Here we show that NR4A nuclear orphan receptors are induced after excitotoxic and oxidative stress in neurons, up-regulate neuroprotective genes, and increase neuronal survival.

Combination of Western blotting, immunocytochemistry, and electrophoresis mobility shift assay showed that KA exposure induced a fast but transient nuclear translocation of the NF-kappaB p65 subunit and increased DNA-binding activity of NF-kappaB in primary cultured cortical neurons.

We demonstrate that activation of nuclear factor kappaB (NF-kappaB) in neurons is neuroprotective in response to kainic acid (KA)-induced excitotoxicity.

Based on these data, we concluded that IKK/nuclear factor-kappaB dependent microglia activation contributes to KA-induced hippocampal neuronal cell death in vivo through induction of inflammatory mediators.

The nuclear translocation of c-Jun and its upregulation are early events following glutamate-induced excitotoxic damage in primary neuronal cultures.

Changes in the expression of these pumps have been implicated in resistance to the macrocyclic lactones, but it is clear that they exert their anthelmintic effects by binding to glutamate-gated chloride channels expressed on nematode neurones and pharyngeal muscle cells.

FSK, histamine, substance P or T. spiralis acute infection caused a 5- to 30-fold increase in cAMP-dependent nuclear CREB phosphorylation in isolated ganglia or calbindin (AH) neurons.

Thus, nuclear calcium-VEGFD signaling mediates the effect of neuronal activity on the maintenance of dendritic arbors in the adult hippocampus and is required for cognitive functioning.

It remains unclear how LD dynamics is regulated in neurons and how the appearance of LDs affects neuronal functions.

However, it is unclear how their expression level in neurons is regulated.

We also report that eEF2K inhibition promotes the nuclear factor erythroid 2-related factor (NRF2) antioxidant response in neuronal cells, which was crucial for the beneficial effects of eEF2K inhibition in neurons exposed to Aβ42 oligomers.

Thus, our results clearly demonstrate that glucose-rich diet aggravates the dopaminergic neuronal dysfunction induced by MCP in C. elegans.

Mutant proteins form intranuclear aggregates, induce cytotoxicity and cause neuronal cell death.

Here, we show that EndoG displays cytotoxic nuclear localization in dopaminergic neurons of human Parkinson-diseased patients, while EndoG depletion largely reduces α-synuclein-induced cell death in human neuroblastoma cells.

During ischemic stroke, malfunction of excitatory amino acid transporters and reduced synaptic clearance causes accumulation of Glutamate (Glu) and excessive stimulation of postsynaptic neurons, which can lead to their degeneration by excitotoxicity.

It remains unclear if Nesprin-1 and 2 regulate other functions in neurons.

In addition, we find that klaroid and klarsicht are required for nuclear migration in differentiating neurons and in non-neural cells.

It is clear to date that the age-induced changes in CNS function observed in invertebrates are conserved in mammalian species and that further work on invertebrates may provide informative insights in to the mechanisms of neuronal ageing.

It is becoming clear that conserved protein complexes, which have been shown to regulate polarity in such diverse systems as the C. elegans zygote and mammalian epithelia, are also required for neuronal polarization.

However, it is still unclear how Aβ and tau aggregates promote specific phenotypic outcomes and lead to excessive oxidative DNA damage, neuronal cell death and eventually to loss of memory.

However, it is unclear whether neuronal hyperactivity is the cause of cognitive impairment or a compensatory mechanism of circuit dysfunction.

Specifically, it is unclear how single neurons influence the processing of sensory information and modulate their responses to environmental changes.

Cytosolic proton ionic increase through inhibition of v-ATPase is sufficient to induce GENTIS nuclear translocation and evoke behavioral quiescence, characterized by reduced feeding and activation of sleep-active neurons.

In conclusion, our findings define a novel conserved signaling cascade coupling injury-induced nuclear export of RNA binding proteins to local regulation and dendrite regeneration, providing new mechanistic insight into neuronal repair.

We show that nuclear localized cyclin D1, an activator of Cdk4/6, is upregulated during kainic acid evoked death of CA3/CA1 neurons and that this upregulation is associated with increased phosphorylation of a critical CDK substrate, pRb.

Using forward genetic screens, we identified the conserved THO nuclear export complex (THOC) as an important regulator of presynapse development in C. elegans dopaminergic neurons.

Our data suggest that the nuclear p53-GAPDH complex is important in regulating glutamate-mediated neuronal death and could serve as a potential therapeutic target for ischemic stroke treatment.

Using the same animal model, the present study evaluated the hypothesis that transcriptional upregulation of NOS II gene by nuclear factor-kappaB (NF-kappaB) promotes apoptotic neuronal cell death in the hippocampus following status epilepticus.

Our results showed that overexpression of the PDZ1 domain of PSD-95 protein could prevent nuclear accumulation and abrogate neuronal cell death in SD (Sprague-Dawley) rat hippocampal neuronal cells.

It could promote the non-amyloidogenic cleavage of the amyloid precursor protein, enhance clearance of amyloid beta-peptides, and reduced neuronal damage through potential inhibition of neuroinflammatory signaling pathways.

These results suggest that DjGAD is clearly required for GABA biosynthesis and photosensitivity in planarians, and expression of DjGAD as detected by anti-DjGAD antibody is a useful marker for GABAergic neurons.

Significant decrease of fluorescence labeled different neurotransmitters, and clear morphological changes by exposure to lindane at 10-100 ng/L suggested that lindane could induce the neuronal damage in C. elegans.
