    • 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) ...

    • Selective and marked decrease of complement receptor C5aR2 in human thoracic aortic aneurysms: A dysregulation with potential inflammatory effects 

      Holt, Margrethe Flesvig; Seim, Bjørn Edvard; Øgaard, Jonas; Olsen, Maria Belland; Woldbæk, Per R; Kvitting, John Peder Escobar; Aukrust, Pål; Yndestad, Arne; Mollnes, Tom Eirik; Nilsson, Per; Louwe, Maria Cornelia; Ranheim, Trine (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-10)
      <i>Objective</i> - The aetiology of thoracic aortic aneurysm (TAA) is largely unknown, but inflammation is likely to play a central role in the pathogenesis. In this present study, we aim to investigate the complement receptors in TAA.<p> <p><i>Methods</i> - Aortic tissue and blood from 31 patients with non-syndromic TAA undergoing thoracic aortic repair surgery were collected. Aortic tissue and ...
