  1. 1. A close-up on neutrophils : Visualizing the mechanisms of their in vivo recruitment and function

    Författare :Sara Massena; Mia Phillipson; Randall S. Jonhson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; angiogenesis; chemokine; chemotactic gradient; citrullination; hypoxia; inflammation; intraluminal crawling; intravital imaging; PAD enzymes; permeability; proangiogenic; proinflammatory;

    Sammanfattning : A successful immune response depends on prompt and sufficient recruitment of leukocytes from the circulation to infected or injured sites. Mobilization of leukocytes to hypoxic tissues is vital for angiogenesis, i.e. the formation of new blood vessels from preexisting vasculature, and thus crucial for tissue growth and regeneration.

  3. 2. JNK/c-Jun Signaling and Peripheral Nerve Regeneration

    Författare :Charlotta Lindwall; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; neuropsykologi; neurofysiologi; neurophysiology; Neurologi; neuropsychology; Neurology; Djurfysiologi; Animal physiology; JNK; signal transduction; nerve regeneration;

    Sammanfattning : The events associated with axonal injury in the peripheral nervous system (PNS) have been described in detail. However, the molecular mechanisms underlying the regenerative response, or neuronal cell death, following axonal injury are poorly understood. LÄS MER

  4. 3. Studies on Peripheral Nerve Regeneration: Microdispensing, Neurite Guidance and Galectins

    Författare :Per Gustavsson; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; vävnadskultur; histokemi; cytokemi; Histologi; tissue culture; histochemistry; cytochemistry; Histology; Schwann cells; sciatic nerve; dorsal root ganglia; DRG; neurite guidance; galectins; inkjet; microdispensing; peripheral nervous system; nerve regeneration; Animal physiology; Djurfysiologi; Biotechnology; Bioteknik;

    Sammanfattning : The present thesis describes development of a microdispenser-based technique to create of protein patterns for neurite guidance. The same technique was also developed to allow direct positioning of dissociated cells, including neurons, on cell culture substrates. Finally the role of galectin-3 and 8 during nerve regeneration was investigated. LÄS MER

  5. 4. Vascular Endothelial Growth Factor (VEGF) and Peripheral Nerve Regeneration

    Författare :Mariann Sondell; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Schwann cell; SCG; rat; peripheral nerve regeneration; neuropilin-1; nerve repair; mouse; growth factor; flk-1; axonal outgrowth; DRG; VEGF; Animal physiology; Djurfysiologi;

    Sammanfattning : This thesis concerns vascular endothelial growth factor (VEGF) and its possible role as a neurotrophic factor. I have investigated the effect of VEGF on neurons in culture but also in vivo, following a crush lesion of the sciatic nerve, and following nerve repair. LÄS MER

  7. 5. Macrophages, Nitric oxide synthases and Heme oxygenases: possible roles during peripheral nerve regeneration

    Författare :Sofia Magnusson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; satellite cells; peripheral ganglia; cell signalling; nerve regeneration; heme oxygenase; Macrophages; nitric oxide synthase; Animal physiology; Djurfysiologi;

    Sammanfattning : The purpose of this study was to investigate the suggestions that macrophages, and the systems generating nitric oxide (NO) and carbon monoxide (CO), i.e. nitric oxide synthases (NOS) and heme oxygenases (HO), could be important for peripheral nerve regeneration. LÄS MER
