• Circulating delta-like Notch ligand 1 is correlated with cardiac allograft vasculopathy and suppressed in heart transplant recipients on everolimus-based immunosuppression 

      Norum, Hilde Margrethe; Michelsen, Annika; Lekva, Tove; Arora, Satish; Otterdal, Kari; Olsen, Maria Belland; Kong, Xiang Yi; Gude, Einar; Andreassen, Arne K.; Solbu, Dag; Karason, Kristjan; Dellgren, Göran; Gullestad, Lars; Aukrust, Pål; Ueland, Thor (Journal article; Tidsskriftartikkel, 2018-10-12)
      Cardiac allograft vasculopathy (CAV) causes heart failure after heart transplantation (HTx), but its pathogenesis is incompletely understood. Notch signaling, possibly modulated by everolimus (EVR), is essential for processes involved in CAV. We hypothesized that circulating Notch ligands would be dysregulated after HTx. We studied circulating delta‐like Notch ligand 1 (DLL1) and periostin (POSTN) ...

      BACKGROUND: In cardiovascular diseases, atherosclerotic disorder are the most frequent and important with respect to morbidity and mortality. Inflammation mediated by immune cells is central in all parts of the atherosclerotic progress, and further understanding of the underlying mechanisms is needed. Growing evidence suggests that deamination of adenosine-toinosine in RNA is crucial for a correct ...
    • Immune complexes, innate immunity, and NETosis in ChAdOx1 vaccine-induced thrombocytopenia

      Aims - We recently reported five cases of vaccine-induced immune thrombotic thrombocytopenia (VITT) 7–10 days after receiving the first dose of the ChAdOx1 nCoV-19 adenoviral vector vaccine against corona virus disease 2019 (COVID-19). We aimed to investigate the pathogenic immunological responses operating in these patients.<p> <p>Methods and results - We assessed circulating inflammatory markers ...
    • Impaired HDL function amplifies systemic inflammation in common variable immunodeficiency 

      Macpherson, Magnhild Eide; Halvorsen, Bente; Yndestad, Arne; Ueland, Thor; Mollnes, Tom Eirik; Berge, Rolf Kristian; Rashidi, Azita; Otterdal, Kari; Gregersen, Ida; Kong, Xiang Yi; Holven, Kirsten Bjørklund; Aukrust, Pål; Fevang, Børre; Jørgensen, Silje Fjellgård (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-01)
      Common variable immunodeficiency (CVID) is the most common symptomatic primary immunodeficiency, characterized by inadequate antibody responses and recurrent bacterial infections. Paradoxically, a majority of CVID patients have non-infectious inflammatory and autoimmune complications, associated with systemic immune activation. Our aim was to explore if HDL, known to have anti-inflammatory properties, ...
    • Legumain is upregulated in acute cardiovascular events and associated with improved outcome – potentially related to anti-inflammatory effects on macrophages

      <i>Background and aims</i> - We have previously found increased levels of the cysteine protease legumain in plasma and plaques from patients with carotid atherosclerosis. This study further investigated legumain during acute cardiovascular events.<p><p> <i>Methods</i> - Circulating levels of legumain from patients and legumain released from platelets were assessed by enzyme-linked-immunosorbent ...
    • A population-based study of inflammatory mechanisms and pain sensitivity 

      Schistad, Ellina Iordanova; Kong, Xiang Yi; Furberg, Anne-Sofie; Bäckryd, Emmanuel; Grimnes, Guri; Emaus, Nina; Rosseland, Leiv Arne; Gordh, Torsten; Stubhaug, Audun; Engdahl, Bo Lars; Halvorsen, Bente Evy; Nielsen, Christopher Sivert (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-10-21)
      Two recent studies suggest that experimental pain sensitivity is associated with low-grade systemic inflammation. However, only 2 biomarkers have been identified, and the studies were conducted in adult individuals where confounding effects of comorbid diseases cannot be excluded. We therefore tested associations between pain sensitivity and 119 inflammation-related serum biomarkers in 827 healthy ...
