  4. 23. 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

    Författare :Biljana Georgievska; Neurobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurologi; Neurology; neuropsykologi; neurofysiologi; neurophysiology; transplantation; tyrosine hydroxylase; tetracycline; striatum; substantia nigra; sprouting; regulation; neuroprotection; lentivirus; gene therapy; GDNF; behavior; dopamine; neuropsychology;

    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.

    Sammanfattning : The intrastriatal 6-hydroxydopamine lesion model in rats is particularly useful in studies testing new therapeutic strategies for Parkinson’s disease. This thesis work (1) describes the characterization of the motor deficits after different types of intrastriatal lesions and identifies the four-site terminal lesion as a model of symptomatic Parkinson’s disease; (2) using the same model, provides evidence that the functional impact of the dopamine cell grafts are dependent on interactions with the host brain; (3) demonstrates that protection or restitution of normal motor function after 6-hydroxydopamine lesions can be achieved if glial cell line-derived neurotrophic factor is administered in the striatum at the time of the terminal fiber degeneration.

  7. 25. Neuroprotective and regenerative actions of GDNF and neurturin on nigral dopamine neurons in rat models of Parkinson’s disease – Prospects for clinical use of neurotrophic factors in neurodegenerative disorders

    Författare :Carl Rosenblad; Neurobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; neurophysiology; neuropsychology; Neurology; striatum; substantia nigra; dopamine; GDNF; neurturin; sprouting; neuroprotection; forelimb akinesia; rotation; tyrosine hydroxylase; transplantation; Neurologi; neuropsykologi; neurofysiologi;

    Sammanfattning : Parkinson’s disease is characterized by progressive degeneration of the nigrostriatal dopamine system, which results in tremor, rigidity, akinesia and postural abnormalities. New therapeutic strategies are aimed at halting the neurodegenerative process or restoring the system by transplantation of fetal dopamine neurons. LÄS MER
