1. 1. Experimental Stroke and Neurotrophins: Regulation, function and gene transfer of neurotrophins in rat and mouse models of focal cerebral ischemia

   Författare :Gunnar Andsberg; Lund Neurologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsychology; Neurology; animal behaviour; striatum; stereology; immunohistochemistry; focal cerebral ischemia; nerve growth factors; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

   Sammanfattning : Stroke caused by focal cerebral ischemia is a major cause of death and neurological disability in humans. The forebrain region most commonly affected by ischemic incidents is that supplied by the middle cerebral artery. LÄS MER

3. 2. 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.

4. 3. Multiple Sclerosis: Studies of the Interferon system and search for infectious agents

   Författare :My Bergkvist; Lund Neurologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; neuropsychology; Neurology; Axon and myelin damage; IgG; Virus; Interferon; Multiple Sclerosis; Genetic linkage;

   Sammanfattning : Multiple sclerosis (MS) is a chronic disease of the central nervous system, characterized by focal inflammatory lesions with demyelination and axonal loss. It is believed that MS is an immune-mediated disorder with both genetic and environmental contributions to the pathogenesis. LÄS MER

5. 4. Neurogenesis and transplantation in stroke-damaged brain

   Författare :Vladimer Darsalia; Lund Neurologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neuropsykologi; neuropsychology; neurophysiology; Neurologi; Neurology; Stroke; Transplantation; Stem cells; Aging; Neurogenesis; neurofysiologi;

   Sammanfattning : Stroke in young adult rodents triggers neurogenesis in the damaged striatum and intact hippocampus. as stroke happens frequently in aged individuals it is of great importance to know whether aging affects brain recovery mechanisms. LÄS MER

7. 5. Death mechanisms compromising hippocampal neurogenesis after status epilepticus

   Författare :Christine Ekdahl Clementson; Lund Neurologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi; minocycline; lipopolysaccharide; microglia activation; status epilepticus; epilepsy; cysteinyl aspartate-specific proteases; apoptosis; neurogenesis; progenitor cell progeny;

   Sammanfattning : Status epilepticus (SE) leads to neurodegeneration as well as neurogenesis in the adult rat hippocampus. This thesis demonstrates that even if the neurogenic response initially is very pronounced, with a several-fold increase in cell proliferation, the survival of the newly formed neurons is compromised by a death mechanism involving mitochondria-related caspases.
