1. Neurotrophic Factor Receptors in the Normal and Injured Visual System : Focus on Retinal Ganglion Cells
Sammanfattning : 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. LÄS MER
2. The Human Spiral Ganglion
Sammanfattning : 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. LÄS MER
3. Modulation of the Progenitor Cell and Homeostatic Capacities of Müller Glia Cells in Retina : Focus on α2-Adrenergic and Endothelin Receptor Signaling Systems
Sammanfattning : 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. LÄS MER
4. Neural Stem and Progenitor Cells as a Tool for Tissue Regeneration
Sammanfattning : 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. LÄS MER
5. Mesenchymal stem cells for repair of the peripheral and central nervous system
Sammanfattning : 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.
