1. GDNF gene delivery in an animal model of Parkinson's disease. Long-term effects on intact, injured and transplanted dopamine neurons using lentiviral gene transfer
Sammanfattning : Parkinson's disease is characterized by a progressive degeneration of dopaminergic neurons in the substantia nigra, leading to a loss of dopamine in the target structure striatum and development of motor symptoms, such as bradykinesia, rigidity and tremor. New experimental treatment strategies for Parkinson's disease are aimed at either preventing the degeneration of the dopaminergic neurons, or at restoring dopamine in the striatum by fetal dopaminergic transplants.

2. 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
3. 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
4. The role of virus neutralization in primate lentivirus pathogenesis
Sammanfattning : The antiviral neutralizing activity of sera from primate lentivirus-infected human and monkey hosts was studied. In addition, factors affecting the neutralization reaction were investigated. In simian immunodeficiency virus (SIVsm)-infected macaque monkeys, SIVsm variants able to escape neutralization emerged regularly. LÄS MER
5. Development of Gene Therapy for Hematopoietic Stem Cells using Lentiviral Vectors
Sammanfattning : Hematopoietic stem cells are an ideal target for genetic manipulation for the purpose of curing hematological disorders as they have the ability to develop into all blood lineages and to self-renew. In this study we demonstrate that lentiviral vectors, based on HIV-1, can efficiently transfer genes into human hematopoietic progenitor and stem cells as assessed following stem cell transplantation in immune compromised mice.
