  1. 11. Role of transcription factors in sensory neuron specification

    Författare :Andreas Montelius; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The interface between our mind and the internal and external environments is the peripheral nervous system. A range of different sensory neuron subtypes detects cold, heat, pain, touch, and other stimuli. LÄS MER

  3. 12. Specification of enteric neuron subtypes in the developing gut

    Författare :Viktoria Knoflach; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The enteric nervous system (ENS) is the biggest subdivision of the peripheral nervous system and harbors more neurons than the spinal cord. Its intricate network of ganglia is spanning the entire length of the gastrointestinal wall from where it controls peristalsis, secretion and blood flow. LÄS MER

  4. 13. The role of Nkx proteins neuronal and glial specification

    Författare :Anna Vallstedt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : During development, different classes of neurons and glia are generated from proliferative progenitor cells lining the ventricles of the brain and the lumen of the spinal cord. A central issue in developmental neuroscience is to understand the mechanisms by which these cells are generated in space and over time. LÄS MER

  5. 14. Essays on Financial Models

    Sammanfattning : This thesis consists of five essays exploring the validity of some extensively used financial models with a focus on the Swedish equity and derivative markets. The essays are of both an empirical and a theoretical nature. LÄS MER

  7. 15. 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
