  1. 1. Dopamine neurons in ventral mesencephalon : interactions with glia and locus coeruleus

    Författare :Elisabet Berglöf; Ingrid Strömberg; Stephen B. Dunnett; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson’s disease; ventral mesencephalon; nerve fiber formation; glia; locus coeruleus; grafting; antioxidant-enriched diet; Histology; Histologi;

    Sammanfattning : Parkinson’s disease is a progressive neurodegenerative disorder, characterized by a depletion of the dopaminergic neurons in the substantia nigra. The cause of the disease is yet unknown but age, oxidative stress, and neuroinflammation are some of the features involved in the degeneration. LÄS MER

  2. 2. Characterization of human dopaminergic neurons in the developing mesencephalon and upon differentiation of stem cells- for replacement therapy in Parkinson´s disease

    Författare :Jenny Nelander Wahlestedt; Utvecklings- och regenerativ neurobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson´s disease; stem cells; ventral mesencephalon; dopaminergic neurons; cell replacement therapy; human fetal tissue; radial glia; microRNA; BAC recombineering; reporter cell lines;

    Sammanfattning : Cell-replacement therapy is a promising approach for treating patients with Parkinson ́s disease (PD). For this purpose, there is a need for developing a protocol that can generate high numbers of human transplantable mesencephalic dopaminer- gic (mesDA) neurons. LÄS MER

  3. 3. 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

  4. 4. GDNF and alpha-synuclein in nigrostriatal degeneration

    Författare :Maria Chermenina; Ingrid Strömberg; Guido Nikkhah; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson s disease; GDNF; ventral mesencephalon; lateral ganglionic eminence; alpha-synuclein; medicinsk utvecklings- och neurobiologi; Developmental Neurosciences;

    Sammanfattning : Parkinson’s disease is a common neurological disorder with a complex etiology. The disease is characterized by a progressive loss of dopaminergic cells in the substantia nigra, which leads to motor function and sometimes cognitive function disabilities. LÄS MER

  5. 5. Identification of dopamine neuron progenitors in the embryonic midbrain and stem cell cultures - Studies on the role of neuronal subtype and differentiation state for cell replacemen in a rodent model of Parkinson's disease

    Författare :Marie Jönsson; Neurobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; GFP; cell sorting; FACS; Transplantation; ventral mesencephalon; embryonic stem cells;

    Sammanfattning : Parkinson’s Disease (PD) is a neurodegenerative disorder where the dopamine producing neurons in the ventral mesencephalon (VM) progressively die and result in symptoms such as resting tremors, muscle rigidity, slowness and difficulties in initiating movements.Currently there is no cure for PD and the available drug treatments only offer symptomatic relief and are often associated with severe side effects.
