  1. 1. Role of Endogenous BDNF and NT3 for Synaptic Transmission and Plasticity in the Dentate gyrus

    Författare :Klara Olofsdotter; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; hippocampus; dentate gyrus; GABA; glutamate; synaptic transmission; synaptic plasticity; Brain-derived neurotrophic factor; neurotrophin 3; Neurologi; neurophysiology; neuropsychology; Neurology; electrophysiology; neurofysiologi; neuropsykologi;

    Sammanfattning : The neurotrophins, notably brain-derived neurotrophic factor (BDNF) and neurotrophin 3 (NT3), modulate synaptic transmission and synaptic plasticity in the adult mammalian brain. Recent data suggest that neurotrophins might be mediators of activity-dependent synaptic plasticity. LÄS MER

  3. 2. Neurotrophic factors and their receptors structure-function relationships and signalling mechanisms

    Författare :Mikael Ryden; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :neurotrophins; nerve growth factor; brain-derived neurotrophic factor; neurotrophin-3; neurotrophin-4; p75 neurotrophin receptor; neuroblastoma; serinethreonine kinase receptors;

    Sammanfattning : Background: The development, survival and maintenance of the vertebrate nervous system requires the continuous supply of a set of polypeptides termed neurotrophic factors. Among these, the neurotrophins (NTs) and members of the transforming growth factor-B (TGF-B) superfamily have raised substantial hopes for future clinical applications. LÄS MER

  4. 3. Genetic aspects on schizophrenia and cerebrospinal fluid monoamine metabolites : focus on association studies with candidate genes

    Författare :Erik Jönsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :association study; schizophrenia; DNA polymorphisms; dopamine receptors DRD2; DRD3; DRD4 ; tyrosine hydroxylase; tryptophan hydroxylase; catechol-O-methyltransferase; neurotrophin-3; ciliary neurotrophic factor; healthy subjects; cerebrospinal fluid;

    Sammanfattning : Schizophrenia is a syndrome with psychotic symptoms. The pathogenesis of schizophrenia most likely reflects brain abnormalities and heritable components are present. The principal objective of the present thesis was to investigate some possible genetic influences in the genesis or pathophysiology of schizophrenia. LÄS MER

  5. 4. Regulation of neurotrophins and their receptors : molecular aspects and functional implications

    Författare :Tuija Salin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :neurotrophin; nerve growth factor; brain-derived neurotrophic factor; neurotrophin-3; neurotrophin-4; glia; gliosis; neuron; tyrosine kinase receptor; transgenic; null mutation; gene; exon; intron; mRNA;

    Sammanfattning : The aim of this work was to study the regulation of neurotrophins and their receptors in a functional aspect. The studies included analysis of neuronal and glial neurotrophin gene expression, that was investigated by using molecular biological techniques. LÄS MER

  7. 5. Mechanisms of Hyperexcitability in the Kindling Model of Epilepsy

    Författare :Eskil Elmer; Sektion IV; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; Neurology; Plasticity; Dentate gyrus; Mossy fibers; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Epilepsy is a syndrome characterized by recurring attacks of sudden, excessive and synchronous discharge in populations of cerebral neurons. Kindling is an animal model for complex partial epilepsy, and is particularly useful for studies on the development of the abnormal excitability underlying the generation and spread of epileptic seizures.
