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

2. Neuroprotection and neurogenesis after experimental stroke
Abstract : 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.

3. Multiple Sclerosis: Studies of the Interferon system and search for infectious agents
Abstract : 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. READ MORE

4. Neurogenesis and transplantation in stroke-damaged brain
Abstract : 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. READ MORE

5. Death mechanisms compromising hippocampal neurogenesis after status epilepticus
Abstract : 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.
