    • Serum PCSK9 is modified by interleukin-6 receptor antagonism in patients with hypercholesterolaemia following non-ST-elevation myocardial infarction 

      Ueland, Thor; Kleveland, Ola; Michelsen, Annika; Wiseth, Rune; Damås, Jan Kristian; Aukrust, Pål; Gullestad, Lars; Halvorsen, Bente; Yndestad, Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-18)
      <p><i>Objective</i>: It is unclear if activation of inflammatory pathways regulates proprotein convertase subtilisin-kexin type 9 (PCSK9) levels.</p> <p><i>Approach</i>: We evaluated (1) the temporal course of serum PCSK9 during hospitalisation following acute coronary syndrome and associations with markers of inflammation (leucocyte counts, interleukin (IL)-6, C-reactive protein) and lipid levels ...

    • Soluble IL-1 receptor 2 is associated with left ventricular remodelling in patients with ST-elevation myocardial infarction 

      Orrem, Hilde Lang; Shetelig, Christian; Ueland, Thor; Limalanathan, Shanmuganathan; Nilsson, Per; Husebye, Trygve Guttorm; Aukrust, Pål; Seljeflot, Ingebjørg; Hoffmann, Pavel; Eritsland, Jan; Mollnes, Tom Eirik; Andersen, Geir Øystein; Yndestad, Arne (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-28)
      <p><i>Background</i>: The inflammatory response following myocardial infarction (MI) is prerequisite for proper healing of infarcted tissue, but can also have detrimental effects on cardiac function. Interleukin (IL)-1α and IL-1β are potent inflammatory mediators and their bioactivity is tightly regulated by IL-1 receptor antagonist (IL-1ra) and soluble (s) IL-1 receptors (R). We aimed to examine ...

    • Soluble markers of neutrophil, T-cell and monocyte activation are associated with disease severity and parasitemia in falciparum malaria 

      Otterdal, Kari; Berg, Åse; Michelsen, Annika; Patel, Sam; Tellevik, Marit Gjerde; Haanshuus, Christel Gill; Fevang, Børre; Aukrust, Pål; Langeland, Nina; Ueland, Thor (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-12-18)
      <i><p>Background</i>: The immune response during P. falciparum infection is a two-edged sword, involving dysregulation of the inflammatory responses with several types of immune cells participating. Here we examined T-cell, monocyte/macrophage and neutrophil activation during P. falciparum infection by using soluble activation markers for these leukocyte subsets.</p> <i><p>Methods</i>: In a ...

    • Tocilizumab increases citrullinated histone 3 in non-ST segment elevation myocardial infarction 

      Helseth, Ragnhild; Kleveland, Ola; Ueland, Thor; Wiseth, Rune; Damås, Jan Kristian; Broch, Kaspar; Michelsen, Annika Elisabet; Bendz, Bjørn; Gullestad, Lars; Aukrust, Pål; Seljeflot, Ingebjørg (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-05-10)
      Objective: Beyond reducing inflammation and troponin T (TnT) release, the interleukin-6 receptor antagonist tocilizumab reduces neutrophil counts in patients with non-ST segment elevation myocardial infarction (NSTEMI). It is unclear if this is related to formation of neutrophil extracellular traps (NETs), carrying inflammatory and thrombotic properties.<p> <p>Methods - In a placebo-controlled ...

    • Wnt5a is associated with right ventricular dysfunction and adverse outcome in dilated cardiomyopathy 

      Abraityte, Aurelija; Lunde, Ida Gjervold; Askevold, Erik Tandberg; Michelsen, Annika E.; Christensen, Geir Arve; Aukrust, Pål; Yndestad, Arne; Fiane, Arnt; Andreassen, Arne; Aakhus, Svend; Dahl, Christen Peder; Gullestad, Lars; Broch, Kaspar; Ueland, Thor (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-06-14)
      The Wingless (Wnt) pathway has been implicated in the pathogenesis of dilated cardiomyopathy (DCM). To explore the role of Wnt modulators Wnt5a and sFRP3 in DCM patients we analyzed the expression of Wnt5a and sFRP3 in plasma and myocardium of DCM patients and evaluated their effects on NFAT luciferase activity in neonatal mouse cardiomyocytes. Elevated circulating Wnt5a (n = 102) was associated ...
