  1. 1. 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

  3. 2. 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

  4. 3. Regeneration of Peripheral Nerves. The role of protein kinases, with emphasis on neurotrophic factor stimulation

    Författare :Peter Wiklund; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NT-4; NT-3; NGF; MAPK; PKG; PKA; PKC; nodose ganglion; DRG; conditioning effect; neurotrophic factors; protein kinases; peripheral; nerve regeneration; BDNF; GDNF; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : The purpose of this study was to investigate the role of protein kinases in peripheral nerve regeneration, with the use of dorsal root ganglia (DRG) and nodose ganglia explants from adult mice. The effects of neurotrophic factor stimulation and protein kinase inhibition were studied for long (days) and short term (minutes) effects. LÄS MER

  5. 4. Development requirements of neurotrophins in the mammalian nervous system

    Författare :Wael M Elshamy; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The survival of the mammalian peripheral nervous system neurons has long been known to depend on neurotrophic factor support during the period of programmed cell death. In fact this was the original hypothesis, put forward after the discovery of the prototype, nerve growth factor (NGF). LÄS MER

  7. 5. Biochemical and biophysical aspects of molecular recognition and signalling by neurotrophins

    Författare :Leopold Luna Ilag; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neurotrophins are members of a family of structurally and functionally related neurotrophic factors that control the development and maintenance of the nervous system. There are currently 5 members which make up this family: nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), neurotrophin-4(NT-4) and neurotrophin-6 (NT-6), which so far is only described in fish.
