Mice deficient in GlyT2 are normal at birth but during the second postnatal week develop a lethal neuromotor deficiency that resembles severe forms of human hyperekplexia (hereditary startle disease) and is characterized by spasticity, tremor, and an inability to right. Histological and immunological analyses failed to reveal anatomical or biochemical abnormalities, but the amplitudes of glycinergic miniature inhibitory currents (mIPSCs) were strikingly reduced in hypoglossal motoneurons and dissociated spinal neurons from GlyT2-deficient mice. Thus, postnatal GlyT2 function is crucial for efficient transmitter loading of synaptic vesicles in glycinergic nerve terminals, and the GlyT2 gene constitutes a candidate disease gene in human hyperekplexia patients."],["dc.identifier.pmid","14622583"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/11248"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/60808"],["dc.language.iso","en"],["dc.relation.issn","0896-6273"],["dc.rights","CC BY-NC-ND 3.0"],["dc.rights.uri","https://creativecommons.org/licenses/by-nc-nd/3.0"],["dc.subject.mesh","Amino Acid Transport Systems, Neutral"],["dc.subject.mesh","Animals"],["dc.subject.mesh","Animals, Newborn"],["dc.subject.mesh","Brain Stem"],["dc.subject.mesh","Disease Models, Animal"],["dc.subject.mesh","Fetus"],["dc.subject.mesh","Gene Deletion"],["dc.subject.mesh","Genes, Lethal"],["dc.subject.mesh","Glycine"],["dc.subject.mesh","Glycine Plasma Membrane Transport Proteins"],["dc.subject.mesh","Heredodegenerative Disorders, Nervous System"],["dc.subject.mesh","Hypoglossal Nerve"],["dc.subject.mesh","Mice"],["dc.subject.mesh","Mice, Knockout"],["dc.subject.mesh","Motor Neurons"],["dc.subject.mesh","Neural Inhibition"],["dc.subject.mesh","Organ Culture Techniques"],["dc.subject.mesh","Phenotype"],["dc.subject.mesh","Presynaptic Terminals"],["dc.subject.mesh","Startle Reaction"],["dc.subject.mesh","Synaptic Transmission"],["dc.subject.mesh","Synaptic Vesicles"],["dc.title","Deletion of the mouse glycine transporter 2 results in a hyperekplexia phenotype and postnatal lethality."],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Here we show that Cb-deficient mice display a region-specific loss of postsynaptic gephyrin and GABA(A) receptor clusters in the hippocampus and the basolateral amygdala. Cb deficiency is accompanied by significant changes in hippocampal synaptic plasticity, due to reduced dendritic GABAergic inhibition. Long-term potentiation is enhanced, and long-term depression reduced, in Cb-deficient hippocampal slices. Consistent with the anatomical and electro-physiological findings, the animals show increased levels of anxiety and impaired spatial learning. Together, our data indicate that Cb is essential for gephyrin-dependent clustering of a specific set of GABA(A) receptors, but not required for glycine receptor postsynaptic localization."],["dc.description.sponsorship","Medical Research Council [G0601585, G0501258]"],["dc.identifier.doi","10.1038/sj.emboj.7601819"],["dc.identifier.isi","000249691800002"],["dc.identifier.pmid","17690689"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/50510"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Nature Publishing Group"],["dc.relation.issn","0261-4189"],["dc.title","Impaired GABAergic transmission and altered hippocampal synaptic plasticity in collybistin-deficient mice"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
