  1. 16. Voltage-dependent anion channels (VDAC) in the plasma membrane induce apoptosis

    Författare :Nesar Akanda; Fredrik Elinder; Tuula Jalonen; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Physiology; Apoptosis; Cell membrane; Hippocampus; Membrane potentials; Neurons; Voltage-dependent anion channels; Medicine; Medicin;

    Sammanfattning : Apoptosis, or programmed cell death, is essential for proper development and functioning of the body systems. During development, apoptosis plays a central role to sculpt the embryo, and in adults, to maintain tissue homeostasis by eliminating redundant, damaged or effete cells. Therefore, a tight regulation of this process is essential. LÄS MER

  3. 17. Expression of sulfatide in rodent CNS - not only restricted to myelin

    Författare :Zarah Pernber; Göteborgs universitet; []
    Nyckelord :sulfatide; glycosphingolipid; neurons; astrocytes; immunohistochemistry; brain; metachromatic leukodystrophy;

    Sammanfattning : Sulfatide is an acidic glycosphingolipid and a component of myelin in the nervous system proposed to be involved in maintenance of the myelin structure and thereby its function. Sulfatide is also a commonly used marker for detection of oligodendrocyte progenitor cells in cultures as well as in tissues. LÄS MER

  4. 18. Anti-epileptic and neuroprotective mechanisms by Topiramate and Levetiracetam evaluated in primary cultures

    Författare :Mikael Ängehagen; Göteborgs universitet; []
    Nyckelord :calcium imaging; phosphorylation; kainate; glutamate; caffeine; cerebral cortex; hippocampus; field potentials; neurons; astrocytes;

    Sammanfattning : The aim of this thesis was to evaluate plausible intracellular mechanisms of action for antiepileptic drugs, Topiramate (TPM) and Levetiracetam (LEV), and to investigate if TPM possesses neuroprotective properties. The thesis is based on results from calcium imaging, immunohistochemical stainings, viability tests, and Western blot using primary cortical or hippocampal cultures, or hippocampal brain slices.

  5. 19. Vascular Endothelial Growth Factor (VEGF) and Peripheral Nerve Regeneration

    Författare :Mariann Sondell; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Schwann cell; SCG; rat; peripheral nerve regeneration; neuropilin-1; nerve repair; mouse; growth factor; flk-1; axonal outgrowth; DRG; VEGF; Animal physiology; Djurfysiologi;

    Sammanfattning : This thesis concerns vascular endothelial growth factor (VEGF) and its possible role as a neurotrophic factor. I have investigated the effect of VEGF on neurons in culture but also in vivo, following a crush lesion of the sciatic nerve, and following nerve repair. LÄS MER

  7. 20. Neuroprotection and neurogenesis after experimental stroke

    Författare :Andreas Arvidsson; Lund Neurologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; stereology; rat; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; BrdU; immunohistochemistry; in situ hybridization; subventricular zone; striatum; dentate gyrus; neuronal replacement; neuronal survival; Focal cerebral ischemia; glial cell line-derived neurotrophic factor;

    Sammanfattning : In this thesis, two potential endogenous mechanisms for neuronal survival and repair have been investigated in a rat model of stroke, middle cerebral artery occlusion (MCAO): signaling of the GDNF family of neurotrophic factors, and neurogenesis from endogenous progenitor cells. As determined by in situ hybridization for GDNF family ligand and receptor genes, MCAO caused widespread upregulation of both components of the functional GDNF receptor, c-Ret and GFRalpha1, indicating that GDNF may be a survival signal in stroke.
