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

    Författare :Niclas Lindqvist; Finn Hallböök; Anders Kvanta; Uppsala universitet; []
    Nyckelord :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;

    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

  3. 2. Retinal ganglion cell examination with Optical Coherence Tomography reflects physiological and pathological changes in the eye and the brain

    Författare :Abbas Al-Hawasi; Neil Lagali; Yumin Link; Per Fagerholm; Per Söderberg; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Retinal ganglion cell; Retinal nerve fiber layer; Optical Coherence Tomography;

    Sammanfattning : The retinal ganglion cell is situated in the inner retina and its axons, composing the retinal nerve fiber layer (RNFL), leave the eye to form the optic nerve. These cells develop embryologically from the forebrain and later during development re-establish connections with different parts of the brain serving different purposes. LÄS MER

  4. 3. Generation of Retinal Neurons : Focus on the Proliferation and Differentiation of the Horizontal Cells and their Subtypes

    Författare :Henrik Boije; Finn Hallböök; Paul Layer; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; FoxN4; Ptf1a; PH3; G2-phase; Cell cycle arrest; Differentiation; Fate; Commitment; Neurogenesis; Follistatin; Neuroscience; Neurovetenskap; Neuroscience; Neurovetenskap;

    Sammanfattning : We have used the chicken retina as a model for investigating cell cycle regulation and cell fate commitment during central nervous system development. This thesis focuses on the characterization of and commitment to the horizontal cell fate in the retina. LÄS MER

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

    Författare :Mohammad Harun-Or-Rashid; Finn Hallböök; Per Ekström; Uppsala universitet; []
    Nyckelord :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;

    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

  7. 5. Selective wavelength pupillometry to evaluate outer and inner retinal photoreception

    Författare :Aki Kawasaki; Fatima Pedrosa Domellöf; Bertil Lindblom; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pupil; pupil light reflex; melanopsin; photoreceptor; intrinsically photosensitive retinal ganglion cell; oftalmiatrik; Ophtalmology;

    Sammanfattning : PurposeIntrinsically photosensitive retinal ganglion cells (ipRGCs) express a unique photopigment called melanopsin. Capable of direct phototransduction, the ipRGCs are also influenced by rods and cones via synaptic inputs. LÄS MER
