1. 1. Functional consequences of dopaminergic degeneration : Clinical and experimental studies using a novel stabilizer of dopaminergic systems

   Författare :Anna Ekesbo; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Parkinson s disease; positron emission tomography; 6-OHDA; MPTP; dyskinesia; dopaminergic degeneration; - -OSU6162; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

   Sammanfattning : Since the introduction of levodopa for the treatment of Parkinson's disease (PD) 30 yearsago, the emergence of motor complications, such as levodopa-induced dyskinesias (LID), hasbeen a major clinical problem in advanced stages of the disease. Clinical and preclinical studieshave revealed a number of functional changes in the dopaminergic system that may be ofimportance for the emergence of LIDs. LÄS MER

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

   Författare :Tandis Vazin; Joakim Lundeberg; Ernest Arenas; KTH; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

4. 3. Mechanisms controlling midbrain dopaminergic neuron development

   Författare :Shanzheng Yang; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : The degeneration of midbrain dopaminergic (mDA) neurons accounts for some of the main motor symptoms of Parkinson’s disease (PD). Efforts during the last decades have focused on understanding how mDA neurons are generated and maintained with the hope of developing novel stem cell-based replacement therapies. LÄS MER

5. 4. Cholinergic and dopaminergic aspects of dementia in Parkinson's disease: postmortem neuropathological findings and modeling of cognitive dysfunction in rodents

   Författare :Helene Hall; Brain Repair and Imaging in Neural Systems (BRAINS); []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alpha-synuclein; animal model; choline acetyltransferase; cholinergic neurons; cognition; dementia; dopaminergic neurons; Lewy bodies; Parkinson s disease; magnetic resonance spectroscopy;

   Sammanfattning : Motor symptoms are currently considered the first clinical hallmark of Parkinson’s disease (PD). They develop as a result of dopamine loss in the striatum, subsequent to the progressive neurodegeneration of dopamin- ergic neurons in the substantia nigra. LÄS MER

7. 5. 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
