In the mammalian brain, new neurons are continuously generated throughout life in the dentate gyrus (DG) of the hippocampus. Previous studies have established that newborn neurons migrate a short distance to be integrated into a preexisting neuronal circuit in the hippocampus. How the migration of newborn neurons is governed by extracellular signals, however, has not been fully understood. Here...
In this issue of Neuron, Clapcote et al. examine mice containing missense mutations of the DISC1 gene, a locus associated with major mental illness in at least one large Scottish family. Genetic manipulation of mouse homologs of genes implicated in the etiology of psychiatric disorders is a promising avenue of research, but also one that is fraught with interpretative difficulties.
We report that the Disc1 gene in all extant 129 mouse inbred substrains has a deletion, previously considered specific to the 129S6/SvEv substrain, which is predicted to abolish production of the full-length protein. This finding has implications for the study of knockout mice generated from 129-derived embryonic stem cells.
Two papers address the contribution of DISC1 to neural development and schizophrenia risk in this issue of Neuron. These complementary studies elegantly bridge the gap between genetic and cellular studies of schizophrenia, providing a level of functional validation that is often lacking in the field.
اسکیزوفرنی بیماری شدید روانی است که حدود 1 درصد از مردم جهان به آن مبتلا هستند. این بیماری چند عاملی با مشارکت شمار زیادی از ژن‌های مستعد کننده که در ارتباط با فرآیندهای اپی‌ژنتیک و عامل‌های محیطی هستند مشخص می‌شود. مطالعات، پیوستگی و همراهی چندین لوکوس را که احتمالاً خطر اسکیزوفرنی را تأیید می‌کنند، مانند نوروگلین1، Disrupted in schizophrenia، دیسبایندین، اپسین 4 و پرولین دهیدروژناز را نشان داد...
Schizophrenia and related disorders have a major genetic component, but despite much effort and many claims, few genes have been consistently replicated and fewer have biological support. One recent exception is "Disrupted in Schizophrenia 1" (DISC1), which was identified at the breakpoint on chromosome 1 of the balanced translocation (1;11)(q42.1;q14.3) that co-segregated in a large Scottish f...
Accumulating evidence suggests an important role for the Disrupted-in-Schizophrenia 1 (DISC1) protein in neurodevelopment and chronic mental illness. In particular, the C-terminal 300 amino acids of DISC1 have been found to mediate important protein-protein interactions and to harbor functionally important phosphorylation sites and disease-associated polymorphisms. However, long disordered regi...
The biology of schizophrenia is complex with multiple hypotheses (dopamine, glutamate, neurodevelopmental) well supported to underlie the disease. Pathways centered on the risk factor "disrupted in schizophrenia 1" (DISC1) may be able to explain and unite these disparate hypotheses and will be the topic of this mini-symposium preview. Nearly a decade after its original identification at the cen...
Association studies, as well as the initial translocation family study, identified the gene Disrupted-In-Schizophrenia-1 (DISC1) as a risk factor for schizophrenia. DISC1 encodes a multifunctional scaffold protein involved in neurodevelopmental processes implicated in the etiology of schizophrenia. The present study explores the contribution of the DISC locus to schizophrenia using three differ...
Viral infection during fetal or neonatal stages increases the risk of developing neuropsychiatric disorders such as schizophrenia and autism spectrum disorders. Although neurons express several key regulators of innate immunity, the role of neuronal innate immunity in psychiatric disorders is still unclear. Using cultured neurons and in vivo mouse brain studies, we show here that Toll-like rece...
