    • Environmental risk factors for multiple sclerosis. Results from animal and human studies on diet, vitamin D and Epstein-Barr virus 

      Torkildsen, Øivind (Doctoral thesis, 2010-01-19)
      Multiple Sclerosis (MS) is an immune mediated disease of the central nervous system (CNS). The aetiology is unknown, but environmental factors as well as multiple separate genetic loci contribute to the disease susceptibility. ...

    • Fingolimod does not enhance cerebellar remyelination in the cuprizone model 

      Alme, Maria Nordheim; Nystad, Agnes Elisabeth; Bø, Lars; Myhr, Kjell-Morten; Vedeler, Christian A.; Wergeland, Stig; Torkildsen, Øivind (Journal article, 2015-08)
      Fingolimod (FTY720) is approved for treatment of relapsing–remitting multiple sclerosis. In vitro studies have found that fingolimod stimulates remyelination in cerebellar slices, but in vivo animal studies have not detected ...

    • In-depth cerebrospinal fluid quantitative proteome and deglycoproteome analysis: presenting a comprehensive picture of pathways and processes affected by multiple sclerosis 

      Kroksveen, Ann Cathrine; Guldbrandsen, Astrid; Vaudel, Marc; Lereim, Ragnhild Reehorst; Barsnes, Harald; Myhr, Kjell-Morten; Torkildsen, Øivind; Berven, Frode (Peer reviewed; Journal article, 2017)
      In the current study, we conducted a quantitative in-depth proteome and deglycoproteome analysis of cerebrospinal fluid (CSF) from relapsing-remitting multiple sclerosis (RRMS) and neurological controls using mass spectrometry ...

    • Inflammation markers in multiple sclerosis: CXCL16 reflects and may also predict disease activity 

      Holmøy, Trygve; Løken-Amsrud, Kristin Ingeleiv; Bakke, Jacob; Beiske, Antonie Giæver; Bjerve, Kristian S; Hovdal, Harald Olav; Lilleås, Finn; Midgard, Rune; Pedersen, Tom; Saltyte Benth, Jurate; Torkildsen, Øivind; Wergeland, Stig; Myhr, Kjell-Morten; Michelsen, Annika; Aukrust, Pål; Ueland, Thor (Peer reviewed; Journal article, 2013-09-19)
      Background. Serum markers of inflammation are candidate biomarkers in multiple sclerosis (MS). ω-3 fatty acids are suggested to have anti-inflammatory properties that might be beneficial in MS. We aimed to explore the ...

    • Level of education and multiple sclerosis risk over a 50-year period: Registry-based sibling study 

      Bjørnevik, Kjetil; Riise, Trond; Benjaminsen, Espen; Celius, Elisabeth Gulowsen; Dahl, Ole-Petter; Kampman, Margitta Theodora; Løken-Amsrud, Kristin Ingeleiv; Midgard, Rune; Myhr, Kjell-Morten; Torkildsen, Øivind; Vatne, Anita; Grytten, Nina (Peer reviewed; Journal article, 2017)
      Background: The conflicting results from studies on socioeconomic status (SES) and multiple sclerosis (MS) risk might be due to a change in the distribution of environmental exposures over time or to methodological limitations ...

    • Magnetization transfer ratio does not correlate to myelin content in the brain in the MOG-EAE mouse model 

      Fjær, Sveinung; Bø, Lars; Myhr, Kjell-Morten; Torkildsen, Øivind; Wergeland, Stig (Peer reviewed; Journal article, 2015-03-02)
      Magnetization transfer ratio (MTR) is a magnetic resonance imaging (MRI) method which may detect demyelination not detected by conventional MRI in the central nervous system of patients with multiple sclerosis (MS). A ...

    • Neurofilament light chain as a biomarker in multiple sclerosis
