  1. 21. Neurons and glia in the peripheral nervous system : interactions in health and disease

    Författare :Filipa Bouçanova; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The peripheral nervous system (PNS) is composed of nerves and ganglia that connect the brain and the spinal cord (the central nervous system, CNS) to the outside world. The nerves contain the extensions (axons) of both sensory and motor neurons, which allow us to detect and respond to different stimuli. LÄS MER

  3. 22. On age related changes in axons and glia of the central nervous system

    Författare :Susanna Kullberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Aging; synaptic input; spinal cord; hippocampus; amino acid neurotransmitters; astrocyte; microglia; oligodendroglia; C bouton; cholinergic; monoaminergic; cytokine;

    Sammanfattning : A growing body of evidence shows that phenotypic changes including axon aberrations, rather than loss of neurons, account for behavioral impairments during aging. The present thesis was undertaken to investigate the occurrence of axon aberrations in relation to transmitter identity, glial reaction and sensorimotor disturbances. LÄS MER

  4. 23. 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

  5. 24. Distribution and function of nicotinic acetylcholine receptors in glia cells and neurons with focus on the neuroprotective mechanisms of cholesterol lowering drugs in Alzheimer's disease

    Författare :Jin Xiu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Nicotinic acetylcholine receptor; Alzheimer s disease; glia cells; Abeta; cholesterol; cholesterollowering drugs;

    Sammanfattning : Nicotinic acetylcholine receptors (nAChRs) are involved in the regulation of many processes including synapses regeneration, neurotransmission and neuroprotection in the central nervous system (CNS). There is increasing evidence for the disturbances in nAChRs in Alzheimer's disease (AD). LÄS MER
