In particular, the specific contribution of risk or candidate gene variants to the complex schizophrenic phenotype is largely unknown. Objective: To prepare the ground for a novel “phenomics” approach, a unique schizophrenia patient database was established by GRAS (Göttingen Research Association for Schizophrenia), designed to allow association of genetic information with quantifiable phenotypes. Because synaptic dysfunction plays a key role in schizophrenia, the complexin 2 gene (CPLX2) was examined in the first phenotype-based genetic association study (PGAS) of GRAS. Design: Subsequent to a classic case-control approach, we analyzed the contribution of CPLX2 polymorphisms to discrete cognitive domains within the schizophrenic population. To gain mechanistic insight into how certain CPLX2 variants influence gene expression and function, peripheral blood mononuclear cells of patients, Cplxnull mutantmice, and transfected cells were investigated.Setting: Coordinating research center (Max Planck Institute of Experimental Medicine) and 23 collaboratingpsychiatric centers all over Germany.Participants: One thousand seventy-one patients with schizophrenia (DSM-IV) examined by an invariant investigator team, resulting in the GRAS database with more than 3000 phenotypic data points per patient, and 1079 healthy control subjects of comparable ethnicity.Main Outcome Measure: Cognitive performance including executive functioning, reasoning, and verbal learning/memory. Results: Six single-nucleotide polymorphisms, distributed over the whole CPLX2 gene, were found to be highly associated with current cognition of schizophrenic subjects but only marginally with premorbid intelligence. Correspondingly, in Cplx2-null mutant mice, prominent cognitive loss of function was obtained only in combination with a minor brain lesion applied during puberty, modeling a clinically relevant environmental risk (“second hit”) for schizophrenia. In the human CPLX2 gene, 1 of the identified 6 cognition-relevant single-nucleotide polymorphisms, rs3822674 in the 3´ untranslated region, was detected to influence microRNA-498 binding and gene expression. The same marker was associated with differential expression of CPLX2 in peripheral blood mononuclear cells. Conclusions: The PGAS allows identification of markerassociated clinical/biological traits. Current cognitive performance in schizophrenic patients is modified by CPLX2 variants modulating posttranscriptional gene expression"],["dc.identifier.doi","10.1001/archgenpsychiatry.2010.107"],["dc.identifier.fs","577608"],["dc.identifier.gro","3150567"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/6097"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7343"],["dc.language.iso","en"],["dc.notes.intern","Migrated from goescholar"],["dc.notes.status","final"],["dc.rights.access","closedAccess"],["dc.subject","Schizophrenia"],["dc.subject.ddc","610"],["dc.title","Modification of cognitive performance in schizophrenia by complexin 2 gene polymorphisms"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","no"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]Details DOI2015Journal Article Research Paper [["dc.bibliographiccitation.firstpage","1480"],["dc.bibliographiccitation.issue","11"],["dc.bibliographiccitation.journal","EMBO Molecular Medicine"],["dc.bibliographiccitation.lastpage","1502"],["dc.bibliographiccitation.volume","7"],["dc.contributor.author","Isernhagen, Antje"],["dc.contributor.author","Malzahn, Doerthe"],["dc.contributor.author","Viktorova, Elena"],["dc.contributor.author","Elsner, Leslie"],["dc.contributor.author","Monecke, Sebastian"],["dc.contributor.author","von Bonin, Frederike"],["dc.contributor.author","Kilisch, Markus"],["dc.contributor.author","Wermuth, Janne Marieke"],["dc.contributor.author","Walther, Neele"],["dc.contributor.author","Balavarca, Yesilda"],["dc.contributor.author","Stahl-Hennig, Christiane"],["dc.contributor.author","Engelke, Michael"],["dc.contributor.author","Walter, Lutz"],["dc.contributor.author","Bickeboeller, Heike"],["dc.contributor.author","Kube, Dieter"],["dc.contributor.author","Wulf, Gerald"],["dc.contributor.author","Dressel, Ralf"],["dc.date.accessioned","2018-11-07T09:49:36Z"],["dc.date.available","2018-11-07T09:49:36Z"],["dc.date.issued","2015"],["dc.description.abstract","The MHC class I chain-related molecule A (MICA) is a highly polymorphic ligand for the activating natural killer (NK)-cell receptor NKG2D.

This stratification coincided with fast (HVL) and slow (LVL) disease progression indicated by the disease course and critical clinical parameters including CD4+ T cell counts.

The dietary supplement palmitoylethanolamide (PEA) exerts anti-inflammatory and neuroprotective properties. Here, we investigated the effect of prophylactic PEA on the early immune response, clinical course, and survival of old mice after intracerebral E. coli K1 infection. Nineteen-month-old wild type mice were treated intraperitoneally with two doses of either 0.1 mg PEA/kg in 250 μl vehicle solution (n = 19) or with 250 μl vehicle solution only as controls (n = 19), 12 h and 30 min prior to intracerebral E. coli K1 infection. The intraperitoneal route was chosen to reduce distress in mice and to ensure exact dosing. Survival time, bacterial loads in cerebellum, blood, spleen, liver, and microglia counts and activation scores in the brain were evaluated. We measured the levels of IL-1β, IL-6, MIP-1α, and CXCL1 in cerebellum and spleen, as well as of bioactive lipids in serum in PEA- and vehicle-treated animals 24 h after infection. In the absence of antibiotic therapy, the median survival time of PEA-pre-treated infected mice was prolonged by 18 h compared to mice of the vehicle-pre-treated infected group (P = 0.031). PEA prophylaxis delayed the onset of clinical symptoms (P = 0.037). This protective effect was associated with lower bacterial loads in the spleen, liver, and blood compared to those of vehicle-injected animals (P ≤ 0.037). PEA-pre-treated animals showed diminished levels of pro-inflammatory cytokines and chemokines in spleen 24 h after infection, as well as reduced serum concentrations of arachidonic acid and of one of its metabolites, 20-hydroxyeicosatetraenoic acid. In the brain, prophylactic PEA tended to reduce bacterial titers and attenuated microglial activation in aged infected animals (P = 0.042). Our findings suggest that prophylactic PEA can counteract infection associated detrimental responses in old animals. Accordingly, PEA treatment slowed the onset of infection symptoms and prolonged the survival of old infected mice.

In complex disorders such as schizophrenia, the overall genetic risk is still often >50% but genotype–phenotype relationships are unclear. Recent genome-wide association studies (GWAS) replicated a risk for several single-nucleotide polymorphisms (SNPs) regarding the endpoint diagnosis of schizophrenia. The biological relevance of these SNPs, however, for phenotypes or severity of schizophrenia has remained obscure. We hypothesized that the GWAS ‘top-10’ should as single markers, but even more so upon their accumulation, display associations with lead features of schizophrenia, namely positive and negative symptoms, cognitive deficits and neurological signs (including catatonia), and/or with age of onset of the disease prodrome as developmental readout and predictor of disease severity. For testing this hypothesis, we took an approach complementary to GWAS, and performed a phenotype-based genetic association study (PGAS). We utilized the to our knowledge worldwide largest phenotypical database of schizophrenic patients (n>1000), the GRAS (Göttingen Research Association for Schizophrenia) Data Collection. We found that the ‘top-10’ GWAS-identified risk SNPs neither as single markers nor when explored in the sense of a cumulative genetic risk, have any predictive value for disease onset or severity in the schizophrenic patients, as demonstrated across all core symptoms. We conclude that GWAS does not extract disease genes of general significance in schizophrenia, but may yield, on a hypothesis-free basis, candidate genes relevant for defining disease subgroups."],["dc.format.extent","6"],["dc.identifier.doi","10.1038/tp.2011.43"],["dc.identifier.gro","3150533"],["dc.identifier.pmid","22833191"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/11388"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/7305"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.rights","CC BY-NC-ND 3.0"],["dc.rights.uri","https://creativecommons.org/licenses/by-nc-nd/3.0"],["dc.subject","Cambridge neurological inventory; cognition; GWAS; PGAS; positive and negative syndrome scale; prodrome"],["dc.title","Dissociation of accumulated genetic risk and disease severity in patients with schizophrenia"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.peerReviewed","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]Details DOI PMID PMC2020Journal Article Research Paper [["dc.bibliographiccitation.firstpage","1018"],["dc.bibliographiccitation.issue","4"],["dc.bibliographiccitation.journal","Journal of Cachexia, Sarcopenia and Muscle"],["dc.bibliographiccitation.lastpage","1031"],["dc.bibliographiccitation.volume","11"],["dc.contributor.author","Zschüntzsch, Jana"],["dc.contributor.author","Jouvenal, Pia Vanessa"],["dc.contributor.author","Zhang, Yaxin"],["dc.contributor.author","Klinker, Florian"],["dc.contributor.author","Tiburcy, Malte"],["dc.contributor.author","Liebetanz, David"],["dc.contributor.author","Malzahn, Dörthe"],["dc.contributor.author","Brinkmeier, Heinrich"],["dc.contributor.author","Schmidt, Jens"],["dc.date.accessioned","2021-04-14T08:26:53Z"],["dc.date.available","2021-04-14T08:26:53Z"],["dc.date.issued","2020"],["dc.description.abstract","Abstract Background Duchenne muscular dystrophy (DMD) is a progressive muscle‐wasting disease caused by mutations in the dystrophin gene, which leads to structural instability of the dystrophin–glycoprotein‐complex with subsequent muscle degeneration. In addition, muscle inflammation has been implicated in disease progression and therapeutically addressed with glucocorticosteroids. These have numerous adverse effects. Treatment with human immunoglobulin G (IgG) improved clinical and para‐clinical parameters in the early disease phase in the well‐established mdx mouse model. The aim of the present study was to confirm the efficacy of IgG in a long‐term pre‐clinical study in mdx mice. Methods IgG (2 g/kg body weight) or NaCl solution as control was administered monthly over 18 months by intraperitoneal injection in mdx mice beginning at 3 weeks of age. Several clinical outcome measures including endurance, muscle strength, and echocardiography were assessed. After 18 months, the animals were sacrificed, blood was collected for analysis, and muscle samples were obtained for ex vivo muscle contraction tests, quantitative PCR, and histology. Results IgG significantly improved the daily voluntary running performance (1.9 m more total daily running distance, P \\u0026lt; 0.0001) and slowed the decrease in grip strength by 0.1 mN, (P = 0.018). IgG reduced fatigability of the diaphragm (improved ratio to maximum force by 0.09 ± 0.04, P = 0.044), but specific tetanic force remained unchanged in the ex vivo muscle contraction test. Cardiac function was significantly better after IgG, especially fractional area shortening (P = 0.012). These results were accompanied by a reduction in cardiac fibrosis and the infiltration of T cells (P = 0.0002) and macrophages (P = 0.0027). In addition, treatment with IgG resulted in a significant reduction of the infiltration of T cells (P ≤ 0.036) in the diaphragm, gastrocnemius, quadriceps, and a similar trend in tibialis anterior and macrophages (P ≤ 0.045) in gastrocnemius, quadriceps, tibialis anterior, and a similar trend in the diaphragm, as well as a decrease in myopathic changes as reflected by a reduced central nuclear index in the diaphragm, tibialis anterior, and quadriceps (P ≤ 0.002 in all). Conclusions The present study underscores the importance of an inflammatory contribution to the disease progression of DMD. The data demonstrate the long‐term efficacy of IgG in the mdx mouse. IgG is well tolerated by humans and could preferentially complement gene therapy in DMD. The data call for a clinical trial with IgG in DMD."],["dc.description.sponsorship","CSL Behring http://dx.doi.org/10.13039/100008322"],["dc.identifier.doi","10.1002/jcsm.12569"],["dc.identifier.pmid","32436338"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/17353"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/82110"],["dc.identifier.url","https://sfb1002.med.uni-goettingen.de/production/literature/publications/355"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-399"],["dc.notes.intern","Merged from goescholar"],["dc.relation","SFB 1002: Modulatorische Einheiten bei Herzinsuffizienz"],["dc.relation","SFB 1002 | S01: In vivo und in vitro Krankheitsmodelle"],["dc.relation.eissn","2190-6009"],["dc.relation.issn","2190-5991"],["dc.relation.workinggroup","RG Tiburcy (Stem Cell Disease Modeling)"],["dc.relation.workinggroup","RG Zimmermann (Engineered Human Myocardium)"],["dc.rights","Goescholar"],["dc.rights.uri","https://goescholar.uni-goettingen.de/licenses"],["dc.title","Long‐term human IgG treatment improves heart and muscle function in a mouse model of Duchenne muscular dystrophy"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]Details DOI PMID PMC
