Bipolar, schizophrenia, and schizoaffective disorders are common, highly heritable psychiatric disorders, for which familial coaggregation, as well as epidemiological and genetic evidence, suggests overlapping etiologies. No definitive susceptibility genes have yet been identified for any of these disorders. Genetic heterogeneity, combined with phenotypic imprecision and poor marker coverage, h...
بیماری میوه سبز مرکبات توسط باکتری سخت کشت candidatus liberobacter asiaticus ایجاد می شود که اولین بار در چین توصیف شده است و در سال 1919 با نام رسمی huanglongbing معرفی گردید. این بیماری یکی از پرخسارت ترین بیماری های مرکبات درجنوب شرقی آسیا، شبه قاره هند، آفریقای جنوبی و شبه جزیره عربستان است. این بیماری در سال 1386 از جنوب ایران گزارش گردید. برای درک مکانیسم مولکولی برهمکنش میزبان-پاتوژن از ...
At the beginning of the 20th century, when neuropathologists had long searched without success for the neural basis of schizophrenia, this field was called a ‘graveyard for neuropathologists ’. This disappointment opened the door for psychiatrists to focus on psychopathology. The discovery of antipsychotic agents in the 1950s provided a clue to understanding the pathology of this difficult dise...
Dysbindin was identified as a dystrobrevin-binding protein potentially involved in the pathogenesis of muscular dystrophy. Subsequently, genetic studies have implicated variants of the human dysbindin-encoding gene, DTNBP1, in the pathogeneses of Hermansky-Pudlak syndrome and schizophrenia. The protein is a stable component of a multisubunit complex termed BLOC-1 (biogenesis of lysosome-related...
Dysbindin has been implicated in the pathogenesis of schizophrenia, but little is known about how dysbindin affects neuronal function in the circuitry underlying psychosis and related behaviors. Using a dysbindin knockout line (dys(-/-)) derived from the natural dysbindin mutant Sandy mice, we have explored the role of dysbindin in dopamine signaling and neuronal function in the prefrontal cort...
The molecular mechanisms underlying the homeostatic modulation of presynaptic neurotransmitter release are largely unknown. We have previously used an electrophysiology-based forward genetic screen to assess the function of >400 neuronally expressed genes for a role in the homeostatic control of synaptic transmission at the neuromuscular junction of Drosophila melanogaster. This screen identifi...
Bipolar disorder and schizophrenia share common chromosomal susceptibility loci and many risk-promoting genes. Oligodendrocyte cell loss and hypomyelination are common to both diseases. A number of environmental risk factors including famine, viral infection, and prenatal or childhood stress may also predispose to schizophrenia or bipolar disorder. In cells, related stressors (starvation, virus...
