2. 1. Dysfunction in the nigrostriatal system : effects of L-DOPA and GDNF

   Author : Nina Nevalainen; Ingrid Strömberg; Nancy Zahniser; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson’s disease; L-DOPA; dyskinesia; GDNF; dopamine; glutamate; serotonin; medicinsk utvecklings- och neurobiologi; Developmental Neurosciences;

   Abstract : Parkinson’s disease is a common neurodegenerative disorder caused by nigrostriatal dopamine loss, with motor deficiencies as the primary outcome. To increase the striatal dopamine content, patients are treated with 3,4-dihydroxyphenyl-l-alanine (l-DOPA). READ MORE

4. 2. Targeted gene transfer in the developing central nervous system using viral vectors

   Author : Simon Stott; Brain Repair and Imaging in Neural Systems (BRAINS); []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; neuropsychology; neurophysiology; Neurologi; Medicin människa och djur ; Medicine human and vertebrates ; gene transfer; in utero; neonatal; GDNF; nigrostriatal; dopamine; AAV; retrovirus; neuropsykologi; neurofysiologi;

   Abstract : Dopamine (DA) is a neurotransmitter that plays a fundamental role in many aspects of normal brain function. The majority of DA neurons in the brain reside in one region ? the midbrain ? and project axonal connections to specific areas. One of the main target regions of the DA system is the striatum.

5. 3. GDNF and alpha-synuclein in nigrostriatal degeneration

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

   Abstract : 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. READ MORE

6. 4. On the influence of glia on neurite outgrowth from dopamine neurons in the nigrostriatal system

   Author : Malin Saga Johansson; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Dopamine; glia; astrocytes; olfactory ensheathing cells; development; ni-grostriatal; mesencephalon; Parkinson s disease; 6-hydroxydopamine;

   Abstract : Interactions between glial cells and neurons are important during fetal development, in the maintenance of the normal functions in tile central nervous system (CNS), arid in response to injuries or diseases. Some of die motor disturbances in Parkinson's disease, a neurodegenerative disorder where one of the hallmarks is degeneration of dopamine (DA) neurons and concomitant depletion of DA in striatum, can be alleviated by intrastriatal grafting of embryonic DA tissue.

7. 5. Nuclear medicine methods in idiopathic Parkinsonism : pre- and postsynaptic dopamine SPECT

   Author : Susanna Jakobson Mo; Katrine Åhlström Riklund; Anne Larsson Strömvall; Lars Forsgren; Rimma Axelsson; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Nuclear medicine; SPECT; 123I-FP-Cit; 123I-IBZM; dopamine; parkinsonism; Parkinson’s disease; multiple system atrophy; progressive supranuclear palsy; Radiology; radiologi;

   Abstract : Background: Single photon emission computed tomography (SPECT) with dopamine transporter (DAT) and dopamine D2 receptor (D2R) ligands can visualise the integrity of the nigrostriatal dopamine system. Parkinson’s disease (PD) and the atypical parkinsonian diseases (APD), progressive supranuclear palsy (PSP) and multiple system atrophy (MSA), have similar symptoms and dopamine depletion, but differ in pharmacological response and prognosis.
