  1. 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

    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.

  2. 2. 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

  3. 3. Functional Analysis of the Vesicular Glutamate Transporter 2 in Specific Neuronal Circuits of the Brain

    Författare :Karin Nordenankar; Åsa Wallén-Mackenzie; Rainer Spanagel; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Addiction; amphetamine; affective behaviour; cocaine; cognitive behaviour; conditional knockout mouse; dopamine; operant self-administration; reward system; schizophrenia; Neuroscience; Neurovetenskap;

    Sammanfattning : A key issue in neuroscience is to determine the connection between neuronal circuits and behaviour. In the adult brain, all neuronal circuits include a glutamatergic component. LÄS MER

  4. 4. Cell Replacement Therapy for Parkinson's Disease: Potential for Circuitry Repair

    Författare :Tiago Cardoso; Utvecklings- och regenerativ neurobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rabies-based tracing; Parkinson s disease cell therapy; Cell Replacement Therapy; Human embryonic stem cells; Dopamine neuron; Synaptic integration; circuitry repair;

    Sammanfattning : The derivation of dopamine neurons from human embryonic stem cells (hESCs) now offers a promising alternative to fetal tissue for cell replacement therapy (CRT) in Parkinson´s disease (PD). Using the appropriate chemical cues in vitro, hESCs can be patterned towards bona-fide ventral midbrain (VM) DA neurons that survive, reinnervate, release DA and provide functional recovery when transplanted into rodent and non-human primate models of PD.

  5. 5. Generation of midbrain dopaminergic neurons in vivo and in vitro: the role of Neurogenin2

    Författare :Elin Andersson; Neurobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine human and vertebrates ; Medicin människa och djur ; cell replacement; Parkinson?s; dopamine; neuronal specification; development; mesencephalon; TH; neuronal differentiation; proneural genes; transcription factors; bHLH; neurospheres; stem cell; progenitor cell;

    Sammanfattning : Parkinsons disease (PD) is a neurodegenerative disorder where dopaminergic neurons of the substantia nigra (SNc) in the mesencephalon are progressively eliminated. The ensuing loss of dopaminergic innervation of the basal ganglia manifests itself as severe motor deficits in PD patients. LÄS MER
