2. 1. Generation of Dopaminergic Neurons from Human Embryonic Stem Cells

   Author : Tandis Vazin; Joakim Lundeberg; Ernest Arenas; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human; dopaminergic; embryonic stem cells; differentiation; stromal cells; PA6 cells; dopamine; neurons; Neuroscience; Neurovetenskap; Neurobiology; Neurobiologi; Molecular neurobiology; Molekylär neurobiologi;

   Abstract : Since the first successful derivation of human embryonic stem cells (hESC), rapid progress has been attained in the development of strategies in differentiation of these cells into various neural lineages, with the fundamental objective of using these cells for replacement and repair of damaged neuronal circuits in the central nervous system (CNS). Of particular interest are midbrain dopaminergic (mDA) neurons, which play a central role in regulation of voluntary movement. READ MORE

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

   Author : Elin Andersson; Neurobiologi; []
   Keywords : 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;

   Abstract : 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. READ MORE

5. 3. On the influence of dopamine-related genetic variation on dopamine-related disorders

   Author : Olle Bergman; Göteborgs universitet; []
   Keywords : dopamine; neurodevelopment; amygdala; schizophrenia; Parkinson s disease; social anxiety disorder; ADHD; PITX3; LMX1A; LMX1B; BDNF; DAT; SNP; genes; genetics; BDNF;

   Abstract : Rationale: Dopamine synthesizing neurons are involved in a wide variety of functions. The most prominent dopamine pathways originate in the midbrain. The development, function and survival of these dopaminergic neurons are under the influence of numerous transcription and neurotrophic factors. READ MORE

6. 4. Up-regulation of dopamine D₂ receptors : in vitro and in vivo studies

   Author : Maria Wanderoy; Eliassitet Eriksson; Stockholms universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurochemistry; Neurokemi; neurokemi och neurotoxikologi; Neurochemistry and Neurotoxicology;

   Abstract : In the central nervous system (CNS) dopaminergic and dopaminoceptive neurons have the ability to respond to variations in dopamine levels by for example adjusting their dopamine receptor levels. One of the most well known phenomena in this respect is that long-term blockade of D2 receptors with antipsychotic drugs leads to an increase in striatal D2 receptor density of experimental animals as well as of schizophrenic patients as measured in both post-mortem studies and in vivo positron emission tomography studies of brain.

7. 5. Generation of dopamine neurons in vivo and from embryonic stem cells in vitro

   Author : Stina Friling; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Mesencephalic dopamine (mesDA) neurons degenerate in patients with Parkinson s disease. In order to develop new treatment strategies for rescuing or replacing degenerating mesDA neurons, an improved understanding of the development and survival of these neurons in the normal brain is required.
