The mammalian neocortex is characterized as a six-layered laminar structure, in which distinct types of pyramidal neurons are distributed coordinately during embryogenesis. In contrast, no other vertebrate class possesses a brain region that is strictly analogous to the neocortical structure. Although it is widely accepted that the pallium, a dorsal forebrain region, is specified in all vertebr...

Reelin is an extracellular matrix protein that regulates neuronal migration in the developing cerebral cortex, and axon outgrowth in the hippocampus. In the developing vomeronasal system, Reelin mRNA is expressed in perineural cells near the vomeronasal nerve, as well as in the vomeronasal organ, olfactory epithelium and olfactory and accessory olfactory bulbs, suggesting that it might regulate...

Reelin, an extracellular glycoprotein is essential for migration and correct positioning of neurons during development. Since the olfactory system is known as a source of various migrating neuronal cells, we studied Reelin expression in the two chemosensory olfactory systems, main and accessory, during early developmental stages of human foetuses/embryos from Carnegie Stage (CS) 15 to gestation...

Reelin is an extracellular matrix protein expressed in several interneuron subtypes in the hippocampus and dentate gyrus. Neuronal nitric oxide synthase (nNOS) is also expressed by interneurons in these areas. We investigated whether reelin and nNOS are co-localized in the same population of hippocampal interneurons, and whether this colocalization is altered in the heterozygous reeler mouse. W...

In the mature cerebral cortex of higher vertebrates, neurons are arranged in layers, each layer containing neurons of the same functional class. The cortical layering pattern is laid down during development by migration of young post-mitotic neurons along glial fibres to their correct positions in the cortical plate. The mechanics of whole-cell movement are well understood, but there is still u...

leads to excessive methylation and hence down regulation of the reelin, GAD67, and other genes, resulting in down regulation of the GABAergic INs (Grayson et al., 2005; Grayson and Guidotti, 2013). The activity of Dnmt is regulated by redox factors at several levels (Hitchler and Domann, 2012; Kang et al., 2012). S-adenosylmethionine (the universal methyl group donor derived from methionine) ma...

Cortical GABAergic dysfunction, a hallmark of both schizophrenia (SZ) and bipolar (BP) disorder pathophysiologies may relate to the hypermethylation of GABAergic gene promoters (i.e., reelin and GAD67). Benefits elicited by a combination of atypical antipsychotics with valproate (VPA) (a histone deacetylase inhibitor that may also activate brain DNA demethylation) in SZ or BP disorder treatment...

schizophrenia affects 1% of population. neonatal ventral hippocampus lesion (nvhl) model of schizophrenia designed in 1993 by lipska and is a widely studied developmental animal model of schizophrenia. nvhl rats mimic many of the symptoms of schizophrenia in detail. we studied this model in molecular level and reelin expression in it. reelin is an extracellular matrix glycoprotein that regulate...

reelin is an extracellular matrix neuroprotein which plays important roles during development and maturation of cerebellum. in the postnatal cerebellum, reelin is synthesized by cerebellar granule cells and secreted to extracellular matrix. this secreted protein modulates adult synaptic function, neurotransmitter release and regulates plasticity. exercise has beneficial effects on central nervo...

Understanding the signals that control migration of neural progenitor cells in the adult brain may provide new therapeutic opportunities. Reelin is best known for its role in regulating cell migration during brain development, but we now demonstrate a novel function for reelin in the injured adult brain. First, we show that Reelin is upregulated around lesions. Second, experimentally increasing...
