Four Unique Interneuron Populations Reside in Neocortical Layer 1
The Journal of Neuroscience, January 2, 2019 • 39(1):125–139 • 125 Systems/Circuits Four Unique Interneuron Populations Reside in Neocortical Layer 1 X Benjamin Schuman,1* XRobert P. Machold,1* Yoshiko Hashikawa,1 Ja´nos Fuzik,1 Gord J. Fishell,2 and X Bernardo Rudy1,3 1Neuroscience Institute, New York University, New York, New York 10016, 2Harvard Medical School and the Stanley Center at the Broad, Cambridge, Massachusetts 02142, and 3Department of Anesthesiology, Perioperative Care and Pain Medicine, New York University School of Medicine, New York, New York 10016 Sensory perception depends on neocortical computations that contextually adjust sensory signals in different internal and environmen- tal contexts. Neocortical layer 1 (L1) is the main target of cortical and subcortical inputs that provide “top-down” information for context-dependent sensory processing. Although L1 is devoid of excitatory cells, it contains the distal “tuft” dendrites of pyramidal cells (PCs) located in deeper layers. L1 also contains a poorly characterized population of GABAergic interneurons (INs), which regulate the impact that different top-down inputs have on PCs. A poor comprehension of L1 IN subtypes and how they affect PC activity has hampered our understanding of the mechanisms that underlie contextual modulation of sensory processing. We used novel genetic strategies in male and female mice combined with electrophysiological and morphological methods to help resolve differences that were unclear when using only electrophysiological and/or morphological approaches. We discovered that L1 contains four distinct popula- tions of INs, each with a unique molecular profile, morphology, and electrophysiology, including a previously overlooked IN population (named here “canopy cells”) representing 40% of L1 INs. -

Received September 7, 2017; Accepted September 29, 2017; Epub October 1, 2017; Published October 15, 2017 Abstract: In this study, we investigated the levels of homeobox A13 (HOXA13) and the mechanisms underlying the co-expressed genes of HOXA13 in lung squamous cancer (LUSC), the signaling pathways in which the co-ex- pressed genes of HOXA13 are involved and their functional roles in LUSC. The clinical significance of 23 paired LUSC tissues and adjacent non-tumor tissues were gathered. HOXA13 levels in LUSC were detected by quantita- tive real-time polymerase chain reaction (qRT-PCR). HOXA13 levels in LUSC from The Cancer Genome Atlas (TCGA) and Oncomine were analyzed. We performed receiver operator characteristic (ROC) curves of various clinicopath- ological features of LUSC. Co-expressed of HOXA13 were collected from MEM, cBioPortal and GEPIA. The func- tions and pathways of the most reliable overlapped genes were achieved from the Gene Otology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) databases, respectively. The protein-protein interaction (PPI) net- works were mapped using STRING. HOXA13 in LUSC were markedly upregulated compared with those in the non- cancerous controls as demonstrated by qRT-PCR (LUSC: 0.330±0.360; CONTROLS: 0.155±0.142; P=0.021). -
1 Evidence for Gliadin Antibodies As Causative Agents in Schizophrenia
1 Evidence for gliadin antibodies as causative agents in schizophrenia. C.J.Carter PolygenicPathways, 20 Upper Maze Hill, Saint-Leonard’s on Sea, East Sussex, TN37 0LG [email protected] Tel: 0044 (0)1424 422201 I have no fax Abstract Antibodies to gliadin, a component of gluten, have frequently been reported in schizophrenia patients, and in some cases remission has been noted following the instigation of a gluten free diet. Gliadin is a highly immunogenic protein, and B cell epitopes along its entire immunogenic length are homologous to the products of numerous proteins relevant to schizophrenia (p = 0.012 to 3e-25). These include members of the DISC1 interactome, of glutamate, dopamine and neuregulin signalling networks, and of pathways involved in plasticity, dendritic growth or myelination. Antibodies to gliadin are likely to cross react with these key proteins, as has already been observed with synapsin 1 and calreticulin. Gliadin may thus be a causative agent in schizophrenia, under certain genetic and immunological conditions, producing its effects via antibody mediated knockdown of multiple proteins relevant to the disease process. Because of such homology, an autoimmune response may be sustained by the human antigens that resemble gliadin itself, a scenario supported by many reports of immune activation both in the brain and in lymphocytes in schizophrenia. Gluten free diets and removal of such antibodies may be of therapeutic benefit in certain cases of schizophrenia. 2 Introduction A number of studies from China, Norway, and the USA have reported the presence of gliadin antibodies in schizophrenia 1-5. Gliadin is a component of gluten, intolerance to which is implicated in coeliac disease 6. -
Thyroid Hormone Influences Brain Gene Expression Programs And

Elena Martinez ● Christine W. Duarte ● J. Patrizia Stohn ● Aldona Karaczyn ● Zhaofei Wu ● 1 1,3,4 Victoria E DeMambro ● Arturo Hernandez Received: 30 March 2018 / Revised: 16 August 2018 / Accepted: 26 September 2018 © Springer Nature Limited 2018 Abstract Genetic factors do not fully account for the relatively high heritability of neurodevelopmental conditions, suggesting that non-genetic heritable factors contribute to their etiology. To evaluate the potential contribution of aberrant thyroid hormone status to the epigenetic inheritance of neurological phenotypes, we examined genetically normal F2 generation descendants of mice that were developmentally overexposed to thyroid hormone due to a Dio3 mutation. Hypothalamic gene expression profiling in postnatal day 15 F2 descendants on the paternal lineage of ancestral male and female T3-overexposed mice 1234567890();,: 1234567890();,: revealed, respectively, 1089 and 1549 differentially expressed genes. A large number of them, 675 genes, were common to both sets, suggesting comparable epigenetic effects of thyroid hormone on both the male and female ancestral germ lines. Oligodendrocyte- and neuron-specific genes were strongly overrepresented among genes showing, respectively, increased and decreased expression. Altered gene expression extended to other brain regions and was associated in adulthood with decreased anxiety-like behavior, increased marble burying and reduced physical activity. The sperm of T3-overexposed male ancestors revealed significant hypomethylation of CpG islands associated with the promoters of genes involved in the early development of the central nervous system. -
NMDA Receptor Dynamics Dictate Neuronal Plasticity and Function
NMDA Receptor Dynamics Dictate Neuronal Plasticity and Function Tommy Weiss Sadan, Ph.D. and Melanie R. Grably, Ph.D. N-Methyl-D-Aspartate Receptor (NMDAR) are ubiquitously expressed along the central nervous system and are instrumental to various physiological processes such as synaptic plasticity and learning. Nevertheless, several mental disabilities including schizophrenia and Alzheimer’s disease are all related to NMDAR dysfunction. Here, we review many aspects of NMDAR function and regulation and describe their involvement in pathophysiological states using Alomone Labs products.

Serotonin Receptor 3A Controls Interneuron Migration Into the Neocortex
ARTICLE Received 3 Sep 2014 | Accepted 9 Oct 2014 | Published 20 Nov 2014 DOI: 10.1038/ncomms6524 OPEN Serotonin receptor 3A controls interneuron migration into the neocortex Sahana Murthy1,2,*, Mathieu Niquille1,2,*, Nicolas Hurni1,2, Greta Limoni1,2, Sarah Frazer1,2, Pascal Chameau3, Johannes A. van Hooft3, Tania Vitalis4 & Alexandre Dayer1,2 Neuronal excitability has been shown to control the migration and cortical integration of reelin-expressing cortical interneurons (INs) arising from the caudal ganglionic eminence (CGE), supporting the possibility that neurotransmitters could regulate this process. Here we show that the ionotropic serotonin receptor 3A (5-HT3AR) is specifically expressed in CGE-derived migrating interneurons and upregulated while they invade the developing cortex. Functional investigations using calcium imaging, electrophysiological recordings and migra- tion assays indicate that CGE-derived INs increase their response to 5-HT3AR activation during the late phase of cortical plate invasion. Using genetic loss-of-function approaches and in vivo grafts, we further demonstrate that the 5-HT3AR is cell autonomously required for the migration and proper positioning of reelin-expressing CGE-derived INs in the neocortex. Our findings reveal a requirement for a serotonin receptor in controlling the migration and laminar positioning of a specific subtype of cortical IN. 1 Department of Mental Health and Psychiatry, University of Geneva Medical School, CH-1211 Geneva 4, Switzerland. 2 Department of Basic Neurosciences, University of Geneva Medical School, CH-1211 Geneva 4, Switzerland. 3 Swammerdam Institute for Life Sciences, Center for NeuroScience, University of Amsterdam, Sciencepark 904, 1098 XH Amsterdam, The Netherlands. 4 CNRS-UMR 8249, Brain Plasticity Unit, ESPCI ParisTech, 10 rue Vauquelin, 75005 Paris, France. -

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -

Sex Differences in Glutamate Receptor Gene Expression in Major Depression and Suicide
Molecular Psychiatry (2015) 20, 1057–1068 © 2015 Macmillan Publishers Limited All rights reserved 1359-4184/15 www.nature.com/mp IMMEDIATE COMMUNICATION Sex differences in glutamate receptor gene expression in major depression and suicide AL Gray1, TM Hyde2,3, A Deep-Soboslay2, JE Kleinman2 and MS Sodhi1,4 Accumulating data indicate that the glutamate system is disrupted in major depressive disorder (MDD), and recent clinical research suggests that ketamine, an antagonist of the N-methyl-D-aspartate (NMDA) glutamate receptor (GluR), has rapid antidepressant efficacy. Here we report findings from gene expression studies of a large cohort of postmortem subjects, including subjects with MDD and controls. Our data reveal higher expression levels of the majority of glutamatergic genes tested in the dorsolateral prefrontal cortex (DLPFC) in MDD (F21,59 = 2.32, P = 0.006). Posthoc data indicate that these gene expression differences occurred mostly in the female subjects. Higher expression levels of GRIN1, GRIN2A-D, GRIA2-4, GRIK1-2, GRM1, GRM4, GRM5 and GRM7 were detected in the female patients with MDD. In contrast, GRM5 expression was lower in male MDD patients relative to male controls. When MDD suicides were compared with MDD non-suicides, GRIN2B, GRIK3 and GRM2 were expressed at higher levels in the suicides. Higher expression levels were detected for several additional genes, but these were not statistically significant after correction for multiple comparisons. In summary, our analyses indicate a generalized disruption of the regulation of the GluRs in the DLPFC of females with MDD, with more specific GluR alterations in the suicides and in the male groups. -
