  1. 41. Wnt signalling in the development of ventral midbrain dopaminergic neurons

    Författare :Gonçalo de Sá e Sousa de Castelo-Branco; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Dopaminergic Neuron; Ventral Midbrain Development; Writs; Dickkopf; beta-catenin; GSK-3beta; Stem Cells; Neural Precursors;

    Sammanfattning : Dopaminergic (DA) neurons in the ventral midbrain (VM) are one of the major cell types lost in Parkinson's disease (PD). Proof-of-principle exists for cell replacement therapies for PD, but wider application is halted by the unavailability of abundant sources of DA neurons. Stem cells might constitute one of these sources. LÄS MER

  3. 42. Neural Stem Cell Differentiation and Migration

    Författare :Anna Erlandsson; Karin Forsberg-Nilsson; Bengt Westermark; Christer Betsholtz; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; CNS; stem cells; neuron; PDGF; SCF; differentiation; migration; ERK; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; Medicinsk biokemi; Medical Biochemistry;

    Sammanfattning : Neural stem cells are the precursors of neurons, astrocytes and oligodendrocytes. During neural development, the division of stem cells takes place close to the lumen of the neural tube, after which they migrate to their final positions within the central nervous system (CNS).

  4. 43. Generating new models to study propagation and pathology of alpha-synuclein in Parkinson's disease and multiple system atrophy

    Författare :Staffan Holmqvist; Stamcellslaboratoriet för sjukdomsmodellering i det centrala nervsystemet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Synucleinopthies are neurodegenerative diseases characterised by the formation of α-synuclein-rich intracellular inclusions in neurons and glia. Traditionally, animalmodels and immortalized cell lines have been used to investigate why and how theseinclusions form, and how they impact on cellular function. LÄS MER

  5. 44. The Non-Invasive Brain Biopsy : Implementation and Application of Quantitative Magnetic Resonance Spectroscopy on Healthy and Diseased Human Brain

    Författare :Anders Tisell; Peter Lundberg; Marcel Warntjes; Anne-Marie Landtblom; Örjan Smedby; Jan Weis; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Introduction: In this thesis, one of the major objectives was to implement a method for (absolute) quantitative magnetic resonance spectroscopy (qMRS) of the human brain, intended for clinical use. The implemented method was based on standard spatially selective MRS sequences. LÄS MER

  7. 45. On neuroinflammation in psychotic disorders

    Författare :Carl Sellgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Neuroinflammation has been implicated in several psychiatric conditions. Based on experimental studies, the glia-derived tryptophan metabolite kynurenic acid (KYNA) may be especially relevant for positive psychotic symptoms and impaired executive functioning. LÄS MER
