1. Astrocytes as Cellular Vehicles in Ex Vivo Gene Therapy Studies to the Rat Brain
Sammanfattning : Neurodegenerative disorders are characterized by a progressive cell-death in the brain, and loss of different functions in the patient. Today, there are no cures for any of the various diseases. Parkinson's disease is a neurodegenerative disorder with a prevalence of 0. LÄS MER
2. Mechanisms of Transgene Silencing in Neural Cells -Implications for Ex Vivo Gene Therapy to the Brain
Sammanfattning : The use of genetically modifi ed neural stem and progenitor cells could possibly be a future strategy for repairing a brain suffering from neurodegeneration. However, so far it has proven diffi cult to maintain sufficient levels of a transferred gene in suitable cell types, after transplantation. LÄS MER
3. Neuronal and glial differentiation of expanded neural stem and progenitor cells; in vitro and after transplantation
Sammanfattning : In this thesis we have used cells dissected from the lateral ganglionic eminence (LGE), the medial ganglionic eminence (MGE), and the cortical primordium of the embryonic mouse forebrain. The tissue was dissected from either i) wild-type mice, ii) green fluorescent protein (GFP)-, or iii) Gtv-a-expressing transgenic mice, and subsequently grown and expanded in vitro using two different protocols.

4. Specific genetic modifications in the CNS - Cell specific expression and gene specific regulation
Sammanfattning : Gene therapy is a promising therapeutic tool for many diseases of the CNS. Lentiviral vectors are particularly attractive since this vector type can transduce both dividing and non-dividing cells, have a relatively large cloning capacity, can sustain long-term transgene expression and have low immunogenicity.

5. Use of neural progenitor cell lines and astrocytes for transplantation and gene transfer to the CNS
Sammanfattning : Intracerebral neuronal transplantation have been shown to ameliorate symptoms of brain dysfunction in both animals models and Parkinson's disease, although problems still remain. The newly introduced technique of ex vivo gene transfer could serve as an alternative approach, possible avoiding some of the draw-backs of the embryonal tissue used in neuronal grafting. LÄS MER
