REST/NRSF drives homeostatic plasticity of inhibitory synapses in a target-dependent fashion. eLife 2021; 10:e69058. [PMID: 34855580 PMCID: PMC8639147 DOI: 10.7554/elife.69058] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Accepted: 11/22/2021] [Indexed: 12/31/2022] Open
Abstract
The repressor-element 1-silencing transcription/neuron-restrictive silencer factor (REST/NRSF) controls hundreds of neuron-specific genes. We showed that REST/NRSF downregulates glutamatergic transmission in response to hyperactivity, thus contributing to neuronal homeostasis. However, whether GABAergic transmission is also implicated in the homeostatic action of REST/NRSF is unknown. Here, we show that hyperactivity-induced REST/NRSF activation, triggers a homeostatic rearrangement of GABAergic inhibition, with increased frequency of miniature inhibitory postsynaptic currents (IPSCs) and amplitude of evoked IPSCs in mouse cultured hippocampal neurons. Notably, this effect is limited to inhibitory-onto-excitatory neuron synapses, whose density increases at somatic level and decreases in dendritic regions, demonstrating a complex target- and area-selectivity. The upscaling of perisomatic inhibition was occluded by TrkB receptor inhibition and resulted from a coordinated and sequential activation of the Npas4 and Bdnf gene programs. On the opposite, the downscaling of dendritic inhibition was REST-dependent, but BDNF-independent. The findings highlight the central role of REST/NRSF in the complex transcriptional responses aimed at rescuing physiological levels of network activity in front of the ever-changing environment.

European Multicentre Tics in Children Studies (EMTICS): protocol for two cohort studies to assess risk factors for tic onset and exacerbation in children and adolescents. Eur Child Adolesc Psychiatry 2019; 28:91-109.

Abstract
Genetic predisposition, autoimmunity and environmental factors [e.g. pre- and perinatal difficulties, Group A Streptococcal (GAS) and other infections, stress-inducing events] might interact to create a neurobiological vulnerability to the development of tics and associated behaviours. However, the existing evidence for this relies primarily on small prospective or larger retrospective population-based studies, and is therefore still inconclusive. This article describes the design and methodology of the EMTICS study, a longitudinal observational European multicentre study involving 16 clinical centres, with the following objectives: (1) to investigate the association of environmental factors (GAS exposure and psychosocial stress, primarily) with the onset and course of tics and/or obsessive-compulsive symptoms through the prospective observation of at-risk individuals (ONSET cohort: 260 children aged 3-10 years who are tic-free at study entry and have a first-degree relative with a chronic tic disorder) and affected individuals (COURSE cohort: 715 youth aged 3-16 years with a tic disorder); (2) to characterise the immune response to microbial antigens and the host's immune response regulation in association with onset and exacerbations of tics; (3) to increase knowledge of the human gene pathways influencing the pathogenesis of tic disorders; and (4) to develop prediction models for the risk of onset and exacerbations of tic disorders. The EMTICS study is, to our knowledge, the largest prospective cohort assessment of the contribution of different genetic and environmental factors to the risk of developing tics in putatively predisposed individuals and to the risk of exacerbating tics in young individuals with chronic tic disorders.

Abstract
Gilles de la Tourette Syndrome (GTS) is characterized by the presence of multiple motor and phonic tics with a fluctuating course of intensity, frequency, and severity. Up to 90% of patients with GTS present with comorbid conditions, most commonly attention-deficit/hyperactivity disorder (ADHD), and obsessive-compulsive disorder (OCD), thus providing an excellent model for the exploration of shared etiology across disorders. TS-EUROTRAIN (FP7-PEOPLE-2012-ITN, Grant Agr.No. 316978) is a Marie Curie Initial Training Network (http://ts-eurotrain.eu) that aims to elucidate the complex etiology of the onset and clinical course of GTS, investigate the neurobiological underpinnings of GTS and related disorders, translate research findings into clinical applications, and establish a pan-European infrastructure for the study of GTS. This includes the challenges of (i) assembling a large genetic database for the evaluation of the genetic architecture with high statistical power; (ii) exploring the role of gene-environment interactions including the effects of epigenetic phenomena; (iii) employing endophenotype-based approaches to understand the shared etiology between GTS, OCD, and ADHD; (iv) establishing a developmental animal model for GTS; (v) gaining new insights into the neurobiological mechanisms of GTS via cross-sectional and longitudinal neuroimaging studies; and (vi) partaking in outreach activities including the dissemination of scientific knowledge about GTS to the public. Fifteen partners from academia and industry and 12 PhD candidates pursue the project. Here, we aim to share the design of an interdisciplinary project, showcasing the potential of large-scale collaborative efforts in the field of GTS. Our ultimate aims are to elucidate the complex etiology and neurobiological underpinnings of GTS, translate research findings into clinical applications, and establish Pan-European infrastructure for the study of GTS and associated disorders.

Investigation of a Possible Role for the Histidine Decarboxylase Gene in Tourette Syndrome in the Chinese Han Population: A Family-Based Study. PLoS One 2016; 11:e0160265.

Abstract
Tourette syndrome (TS) is a polygenic neuropsychiatric disease. Previous studies have indicated that dysregulation in the histaminergic system may play a crucial role in disease onset. In this study, we investigated the role of the histidine decarboxylase gene (HDC) in TS susceptibility in the Chinese Han population. After genotyping 241 TS nuclear families trios, we analyzed three tag HDC single nucleotide polymorphisms (rs854150, rs854151, and rs854157) in a family-based study using the transmission disequilibrium test (TDT) and haplotype relative risk (HRR). TDT showed no over-transmission in these SNPs across the HDC region (for rs854150: χ2 = 0.472, P = 0.537, OR = 1.097, 95%CI = 0.738–1.630; for rs854151: χ2 = 0.043, P = 0.889, OR = 1.145, 95%CI = 0.767–1.709; for rs854157:χ2 = 0.984, P = 0.367, OR = 1.020, 95%CI = 0.508–2.049). HRR also showed the same tendency (for rs854150: χ2 = 0.211, P = 0.646, OR = 1.088, 95%CI = 0.759–1.559; for rs854151: χ2 = 0.134, P = 0.714, OR = 0.935, 95%CI = 0.653–1.339; for rs854157:χ2 = 0.841, P = 0.359, OR = 1.206, 95%CI = 0.808–1.799). Additionally, the haplotype-based haplotype relative risk showed a negative association. Although these findings indicate an unlikely association between HDC and TS in the Chinese Han population, a potential role for HDC cannot be ruled out in TS etiology. Future research should investigate this more thoroughly using different populations and larger samples.

Abstract
The recent paradigm shift towards a more biologically oriented definition of Alzheimer's disease (AD) in clinical settings increases the need for sensitive biomarkers that can be applied in population-based settings. Blood plasma is easily accessible and contains a large number of proteins related to cerebral processes. It is therefore an ideal candidate for AD biomarker discovery. The present chapter provides an overview of the current research landscape in relation to blood-based AD biomarkers. Both clinical and methodological issues are covered. A brief summary is given on two relevant laboratory techniques to ascertain blood biomarker changes due to AD; methodological and clinical challenges in the field are also discussed.

Abstract
Less-invasive biomarkers for early Alzheimer disease (AD) are urgently needed. The present study aimed to establish a panel of plasma proteins that accurately distinguishes early AD from physiological aging and to compare the findings with previous reports. Fifty-eight healthy controls (CON) and 109 patients with AD dementia were randomly split into a training (40%) and a test (60%) sample. Significant proteins to differentiate between the CON and AD dementia groups were identified in a comprehensive panel of 107 plasma analytes in the training sample; the accuracy in differentiating these 2 groups was explored in the test sample. A set of 5 plasma proteins was identified, which differentiated between the CON group and the AD dementia group with a sensitivity of 89.36% and a specificity of 79.17%. A biological pathway analysis showed that 4 of 5 proteins belonged to a common network with amyloid precursor protein and tau. Apolipoprotein E was the only protein that was both significant in the present report and in a previous proteomic study. The study provides a piece of evidence in support of the feasibility of a blood-based biomarker approach in AD diagnostics; however, further research is required because of issues with replicability.

BIOCHIMICA ET BIOPHYSICA ACTA-GENE REGULATORY MECHANISMS 2013; 1839:13-24. [PMID: 24291638 DOI: 10.1016/j.bbagrm.2013.11.004] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/25/2013] [Revised: 11/18/2013] [Accepted: 11/19/2013] [Indexed: 12/31/2022]
Abstract
NPAS4 is a brain restricted, activity-induced transcription factor which regulates the expression of inhibitory synapse genes to control homeostatic excitatory/inhibitory balance in neurons. NPAS4 is required for normal social interaction and contextual memory formation in mice. Protein and mRNA expression of NPAS4 is tightly coupled to neuronal depolarization and most prevalent in the cortical and hippocampal regions in the brain, however the precise mechanisms by which the NPAS4 gene is controlled remain unexplored. Here we show that expression of NPAS4 mRNA is actively repressed by RE-1 silencing transcription factor/neuron-restrictive silencer factor (REST/NRSF) in embryonic stem cells and non-neuronal cells by binding multiple sites within the promoter and Intron I of NPAS4. Repression by REST also appears to correlate with the binding of the zinc finger DNA binding protein CTCF within Intron I of NPAS4. In addition, we show that the 3' untranslated region (3'UTR) of NPAS4 can be targeted by two microRNAs, miR-203 and miR-224 to further regulate its expression. miR-224 is a midbrain/hypothalamus enriched microRNA which is expressed from an intron within the GABAA receptor epsilon (GABRE) gene and may further regionalize NPAS4 expression. Our results reveal REST and microRNA dependent mechanisms that restrict NPAS4 expression to the brain.

Abstract
Family studies have consistently shown that Tourette syndrome (TS) is a familial disorder and twin studies have clearly indicated a genetic contribution in the etiology of TS. Whereas early segregation studies of TS suggested a single-gene autosomal dominant disorder, later studies have pointed to more complex models including additive and multifactorial inheritance and likely interaction with genetic factors. While the exact cellular and molecular base of TS is as yet elusive, neuroanatomical and neurophysiological studies have pointed to the involvement of cortico-striato-thalamocortical circuits and abnormalities in dopamine, glutamate, gamma-aminobutyric acid, and serotonin neurotransmitter systems, with the most consistent evidence being available for involvement of dopamine-related abnormalities, that is, a reduction in tonic extracellular dopamine levels along with hyperresponsive spike-dependent dopamine release, following stimulation. Genetic and gene expression findings are very much supportive of involvement of these neurotransmitter systems. Moreover, intriguingly, genetic work on a two-generation pedigree has opened new research pointing to a role for histamine, a so far rather neglected neurotransmitter, with the potential of the development of new treatment options. Future studies should be aimed at directly linking neurotransmitter-related genetic and gene expression findings to imaging studies (imaging genetics), which enables a better understanding of the pathways and mechanisms through which the dynamic interplay of genes, brain, and environment shapes the TS phenotype.

Catecholamine-related gene expression in blood correlates with tic severity in tourette syndrome. Psychiatry Res 2012; 200:593-601. [PMID: 22648010 DOI: 10.1016/j.psychres.2012.04.034] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2011] [Revised: 04/24/2012] [Accepted: 04/26/2012] [Indexed: 12/24/2022]
Abstract
Tourette syndrome (TS) is a heritable disorder characterized by tics that are decreased in some patients by treatment with alpha adrenergic agonists and dopamine receptor blockers. Thus, this study examines the relationship between catecholamine gene expression in blood and tic severity. TS diagnosis was confirmed using Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV criteria and tic severity measured using the Yale Global Tic Severity Scale (YGTSS) for 26 un-medicated subjects with TS. Whole blood was collected and Ribonucleic acid (RNA) processed on Affymetrix Human Exon 1.0 ST arrays. An Analysis of Covariance (ANCOVA) identified 3627 genes correlated with tic severity (p<0.05). Searches of Medical Subject Headings, Gene Ontology, Allen Mouse Brain Atlas, and PubMed determined genes associated with catecholamines and located in the basal ganglia. Using GeneCards, PubMed, and manual curation, seven genes associated with TS were further examined: DRD2, HRH3, MAOB, BDNF, SNAP25, SLC6A4, and SLC22A3. These genes are highly associated with TS and have also been implicated in other movement disorders, Attention Deficit Hyperactivity Disorder (ADHD), and Obsessive-Compulsive Disorder (OCD). Correlation of gene expression in peripheral blood with tic severity may allow inferences about catecholamine pathway dysfunction in TS subjects. Findings built on previous work suggest that at least some genes expressed peripherally are relevant for central nervous system (CNS) pathology in the brain of individuals with TS.

Abstract
To evaluate whether gene expression in chromosome 15q13-q22.3 region is responsible for the development of Tourette syndrome (TS). Eighty-four unrelated Chinese Han patients with TS (male/female = 68/16; mean age 9.92 ± 3.98 years) and 100 sex, age, and ethnicity matched normal controls (male/female = 80/20; mean age 10.90 ± 5.86 years) were enrolled in this study. We performed quantitative real-time PCR on a subset of seven genes: the L-histidine decarboxylase gene (HDC), the HECT domain and RCC-1 like domain 1 gene (HERC1), the HECT domain and RCC-1 like domain 2 gene (HERC2), the cholinergic receptor, neuronal nicotinic alpha polypeptide 7 gene (CHRNA7), the ubiquitin protein ligase E3A gene (UBE3A), the ubiquitin specific peptidase 3 gene (USP3) and the amyloid precursor protein-binding protein A2 gene (APBA2) previously reported to be stably expressed in brain tissue. A significant difference was shown for the APBA2 gene expression of peripheral lymphocytes between Chinese Han TS group and healthy controls (relative expression: 0.21 ± 0.16-fold decrease in patients versus normal, P < 0.01). Indicating that the APBA2 gene is a promising peripheral blood biomarker that discriminates between patients with TS and healthy subjects. Further studies into this gene and its protein products may provide insights into the pathogenesis of TS.
