  2. 1. Neurotrophic Factor Receptors in the Normal and Injured Visual System : Focus on Retinal Ganglion Cells

    Author : Niclas Lindqvist; Finn Hallböök; Anders Kvanta; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; cell survival; gene expression; neurotrophic factor; receptor; retina; visual system; Neurovetenskap; Neurology; Neurologi; Developmental Neurosciences; Medicinsk utvecklings- och neurobiologi;

    Abstract : The focus of this thesis is the life and death of adult retinal ganglion cells (RGCs). RGCs are neurons that convey visual information from the retina to higher centers in the brain. READ MORE

  4. 2. The Human Spiral Ganglion

    Author : Sven Tylstedt; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Otorhinolaryngology; human spiral ganglion; ultrastructural morphology; neural interaction; synaptophysin; connexin; membrane specializations; synapse; gap junction; tight junction; Otorhinolaryngologi; Otorhinolaryngology; Otorhinolaryngologi; Oto-Rhino-Laryngology; oto-rhino-laryngologi;

    Abstract : Our knowledge of the fine structure of the Human Spiral Ganglion (HSG) is still inadequate and new treatment techniques for deafness using electric stimulation, call for further information and studies on the neuronal elements of the human cochlea. This thesis presents results of analyses of human cochlear tissue and specimens obtained during neurosurgical transpetrosal removal of life-threatening meningeomas. READ MORE

  5. 3. Modulation of the Progenitor Cell and Homeostatic Capacities of Müller Glia Cells in Retina : Focus on α2-Adrenergic and Endothelin Receptor Signaling Systems

    Author : Mohammad Harun-Or-Rashid; Finn Hallböök; Per Ekström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Alpha2-adrenergic receptor; Brimonidine; Brn3a; Dedifferentiation; Endothelin; EGFR; ERK1 2; Neuroprotection; NMDA; MIO-M1 human Müller cell; Müller cells; Retina; Retinal ganglion cells; Src-kinase; Transactivation.; Medical Science; Medicinsk vetenskap;

    Abstract : Müller cells are major glial cells in the retina and have a broad range of functions that are vital for the retinal neurons. During retinal injury gliotic response either leads to Müller cell dedifferentiation and formation of a retinal progenitor or to maintenance of mature Müller cell functions. READ MORE

  6. 4. Neural Stem and Progenitor Cells as a Tool for Tissue Regeneration

    Author : Ulrika Wallenquist; Karin Forsberg Nilsson; Lars Hillered; Karin Holmqvist; Anders Lewén; Johan Bengzon; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; traumatic brain injury; neural stem cells; transplantation; CNS; PNS; progenitor cells; inflammation; CCI; Biochemistry; Biokemi; Neurosurgery; neurokirurgi; Medical Biochemistry; medicinsk biokemi;

    Abstract : Neural stem and progenitor cells (NSPC) can differentiate to neurons and glial cells. NSPC are easily propagated in vitro and are therefore an attractive tool for tissue regeneration. Traumatic brain injury (TBI) is a common cause for death and disabilities. A fundamental problem following TBI is tissue loss. READ MORE

  7. 5. Mesenchymal stem cells for repair of the peripheral and central nervous system

    Author : Maria Brohlin; Mikael Wiberg; Martin Birchall; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bone marrow-derived stromal cells; Schwann cells; Peripheral nerve injury; Spinal cord injury; Neurotransplantation; anatomi; Human Anatomy; cell research; cellforskning;

    Abstract : Bone marrow-derived mesenchymal stem cells (MSC) have been shown to provide neuroprotection after transplantation into the injured nervous system. The present thesis investigates whether adult human and rat MSC differentiated along a Schwann cell lineage could increase their expression of neurotrophic factors and promote regeneration after transplantation into the injured peripheral nerve and spinal cord.
