  1. 11. 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

  3. 12. Plasticity and variation of synaptic responses in hippocampus. Role of AMPA and NMDA receptors

    Författare :Yin-Ping Niu; Göteborgs universitet; []
    Nyckelord :learning and memory; synaptic plasticity; hippocampus; synapse; AMPA receptor; NMDA receptor; LTP; LTD; CV; TFS;

    Sammanfattning : It is generally believed that synaptic plasticity in the central nervous system may underlie learning and memory as well as neuronal development. The most wellstudied examples of such synaptic plasticity are long-term potentiation (LTP) andlong-term depression (LTD). LÄS MER

  5. 14. Developmental plasticity of the glutamate synapse: Roles of low frequency stimulation, hebbian induction and the NMDA receptor

    Författare :Joakim Strandberg; Göteborgs universitet; []
    Nyckelord :AMPA receptor; Development; Glutamate; Hippocampus; Long-term depression; Long-term potentiation; NMDA receptor; Synaptic depression;

    Sammanfattning : The glutamate synapse is by far the most common synapse in the brain and acts via postsynaptic AMPA, NMDA and mGlu receptors. During brain development there is a continuous production of these synapses where those partaking in activity resulting in neuronal activity are subsequently selected to establish an appropriate functional pattern of synaptic connectivity while those that do not are elimimated.

  7. 15. NMDA receptors in neurodegeneration : studies on NMDA receptor subunit expression preceding ischemia-induced delayed nerve cell death

    Författare :Olof Bendel; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : NMDA receptors are glutamate-gated ion channels that are permeable to Ca2+. NMDA receptors are tetramers formed by a combination of subunits. In the present thesis, we describe the novel NR3B subunit that we cloned in mouse and human. NR3B was found to be expressed in the adult rat and human central nervous system (CNS). LÄS MER
