      Background: Anti interferon-beta (IFN-β) neutralizing antibodies (NAb) affect efficacy of treatment of multiple sclerosis patients, but exactly when the detrimental effects of NAbs offset therapeutic efficacy is debated. ...
    • Evaluation of interferon-beta neutralizing antibodies in individual patients with multiple sclerosis based on phospho-specific flow cytometry 

      Gavasso, Sonia (Doctoral thesis; Peer reviewed, 2013-03-19)
      Background: Recombinant human interferon-beta (IFN-β) is the most frequently used drug for treating relapsing-remitting multiple sclerosis (RRMS), a demyelinating disease of the central nervous system. It modulates the ...
    • Optimization of receptor occupancy assays in mass cytometry: Standardization across channels with QSC beads 

      Bringeland, Gerd Haga; Bader, Lucius; Blaser, Nello; Budzinski, Lisa; Schulz, Axel R.; Mei, Henrik E.; Myhr, Kjell-Morten; Vedeler, Christian A.; Gavasso, Sonia (Peer reviewed; Journal article, 2019)
      Receptor occupancy, the ratio between amount of drug bound and amount of total receptor on single cells, is a biomarker for treatment response to therapeutic monoclonal antibodies. Receptor occupancy is traditionally ...
    • Signaling effects of sodium hydrosulfide in healthy donor peripheral blood mononuclear cells 

      Sulen, Andre; Gullaksen, Stein-Erik; Bader, Lucius; McClymont, David; Skavland, Jørn; Gavasso, Sonia; Gjertsen, Bjørn Tore (Peer reviewed; Journal article, 2016-11)
      Hydrogen sulfide (H2S) is an endogenous gasotransmitter in human physiology and inflammatory disease, however, with limited knowledge of how signal transduction pathways are involved in immune cells. To examine the effects ...
    • Single cell based phosphorylation profiling identifies alterations in toll-like receptor 7 and 9 signaling in patients with primary Sjögren's syndrome 

      Davies, Richard Allan; Sarkar, Irene; Hammenfors, Daniel; Bergum, Brith; Vogelsang, Petra; Solberg, Silje Michelsen; Gavasso, Sonia; Brun, Johan G; Jonsson, Roland; Appel, Silke (Peer reviewed; Journal article, 2019-02-21)
      Primary Sjögren's syndrome (pSS) is associated with polymorphisms and mRNA expression profiles that are indicative of an exaggerated innate and type I IFN immune response. Excessive activation potential of signaling pathways ...
    • Single cell immune profiling by mass cytometry of newly diagnosed chronic phase chronic myeloid leukemia treated with nilotinib 

      Gullaksen, Stein-Erik; Skavland, Jørn; Gavasso, Sonia; Tosevski, Vinko; Warzocha, Krzysztof; Dumrese, Claudia; Ferrant, Augustin; Gedde-Dahl, Thobias; Hellmann, Andrzej; Janssen, Jeroen; Labar, Boris; Lang, Alois; Majeed, Mohammed Waleed; Mihaylov, Georgi; Stentoft, Jesper; Stenke, Leif; Thaler, Josef; Thielen, Noortje; Verhoef, Gregor; Voglova, Jaroslava; Ossenkoppele, Gert; Hochhaus, Andreas; Hjorth-Hansen, Henrik; Mustjoki, Satu; Sopper, Sieghart; Giles, Francis; Porkka, Kimmo; Wolf, Dominik; Gjertsen, Bjørn Tore (Peer reviewed; Journal article, 2017-08)
      Monitoring of single cell signal transduction in leukemic cellular subsets has been proposed to provide deeper understanding of disease biology and prognosis, but has so far not been tested in a clinical trial of targeted ...
    • Titrating complex mass cytometry panels 

      Gullaksen, Stein-Erik; Bader, Lucius; Hellesøy, Monica; Sulen, Andre; Fagerholt, Oda Helen Eck; Engen, Caroline Benedicte Nitter; Skavland, Jørn; Gjertsen, Bjørn Tore; Gavasso, Sonia (Peer reviewed; Journal article, 2019-07-13)
      We describe here a simple and efficient antibody titration approach for cell‐surface markers and intracellular cell signaling targets for mass cytometry. The iterative approach builds upon a well‐characterized backbone ...
    • Wearing-off at the end of natalizumab dosing interval and risk of MS disease activity: A prospective 1-year follow-up study 

      Bringeland, Gerd Haga; Myhr, Kjell-Morten; Vedeler, Christian A.; Gavasso, Sonia (Journal article; Peer reviewed, 2020)
      Natalizumab effectively prevents disease activity in relapsing-remitting multiple sclerosis by binding α4 integrin and inhibiting leukocyte migration to the central nervous system. We recently reported an association between ...
    • Wearing-off at the end of natalizumab dosing intervals is associated with low receptor occupancy
