OBJECTIVE Neuregulin-1 (NRG1) has been put forward as a susceptibility gene for schizophrenia. We investigated the association between Neuregulin-1 and the P300 wave, a schizophrenia endophenotype. METHODS Participants were 64 patients with DSM-IV schizophrenia or schizoaffective disorder, 97 of their non psychotic relatives and 35 unrelated controls. The P300 wave was extracted from the elec...

D ata from twin, family, and adoption studies provide strong evidence that genetic factors play a major aetiological role in schizophrenia. By a series of linkage studies, chromosome 8p has been implicated as a region harbouring a schizophrenia susceptibility gene. Recently, Stefansson and colleagues reported that neuregulin 1 (NRG1), located in 8p21-12, may be involved in the aetiology of schi...

Neuregulin 1 (NRG1) has been identified as a susceptibility gene for schizophrenia, and dysregulation of NRG1 and its ErbB receptors is implicated in the pathophysiology of the disorder. The present study examined the protein expression levels of NRG1beta, ErbB2, ErbB3 and ErbB4 in the rat prefrontal cortex and hippocampus following a 4-wk administration of haloperidol (1 mg/kg i.p.), clozapine...

Synaptic connections in the nervous system are rearranged during development and in adulthood as a feature of growth, plasticity, aging, and disease. Glia are implicated as active participants in these changes. Here we investigated a signal that controls the participation of peripheral glia, the terminal Schwann cells (SCs), at the neuromuscular junction (NMJ) in mice. Transgenic manipulation o...

Schizophrenia is one of the most common and complex neuropsychiatric disorders, which is contributed both by genetic and environmental exposures. Recently, it is shown that NRG1-mediated ErbB4 signalling regulates many important cellular and molecular processes such as cellular growth, differentiation and death, particularly in myelin-producing cells, glia and neurons. Recent association studie...

S chizophrenia is a devastating brain disease that affects ∼1% of the population worldwide and is characterized by a complex array of positive (delusions and hallucinations), negative (apathy and social withdrawal), and cognitive (deficits in attention and working memory) symptoms. Clinical features of schizophrenia frequently arise during late adolescence or early adulthood, which places this ...

OBJECTIVE Neuregulin1 (NRG1) gene is among the most promising candidate genes for schizophrenia. This gene is located on 8p22-p12, a region with a reported linkage to schizophrenia. Several studies have reported an association between schizophrenia and the 5' end polymorphisms in this gene. However, some studies have failed to confirm the role of NRG1 gene in the pathogenesis of schizophrenia. ...

Candida albicans is a dimorphic fungus that can interconvert between yeast and filamentous forms. Its ability to regulate morphogenesis is strongly correlated with virulence. Tup1, a transcriptional repressor, and the signaling molecule farnesol are both capable of negatively regulating the yeast to filamentous conversion. Based on this overlap in function, we tested the hypothesis that the cel...
