      Larssen, Eivind; Brede, Cato; Hjelle, Anne; Tjensvoll, Anne Bolette; Norheim, Katrine Brække; Bårdsen, Kjetil; Jonsdottir, Kristin; Ruoff, Peter; Omdal, Roald; Nilsen, Mari Mæland (Journal article; Peer reviewed, 2019)
      Objectives: Fatigue is a frequent and often disabling phenomenon that occurs in patients with chronic inflammatory and immunological diseases, and the underlying biological mechanisms are largely unknown. Because fatigue ...
    • Heat shock proteins and chronic fatigue in primary Sjögren's syndrome 

      Bårdsen, Kjetil; Mæland, Mari; Kvaløy, Jan Terje; Norheim, Katrine Brække; Jonsson, Grete; Omdal, Roald (Peer reviewed; Journal article, 2016)
      Fatigue occurs frequently in patients with cancer, neurological diseases and chronic inflammatory diseases, but the biological mechanisms that lead to and regulate fatigue are largely unknown. When the innate immune system ...
    • Interleukin-1-related activity and hypocretin-1 in cerebrospinal fluid contribute to fatigue in primary Sjögren’s syndrome 

      Bårdsen, Kjetil; Brede, Cato; Kvivik, Ingeborg; Kvaløy, Jan Terje; Jonsdottir, Kristin; Tjensvoll, Anne Bolette; Ruoff, Peter; Omdal, Roald (Journal article; Peer reviewed, 2019)
      Background Fatigue is a common and sometimes debilitating phenomenon in primary Sjögren’s syndrome (pSS) and other chronic inflammatory diseases. We aimed to investigate how IL-1 β-related molecules and the neuropeptide ...
    • Investigation of serum protein profiles in scrapie infected sheep by means of SELDI-TOF-MS and multivariate data analysis 

      Meling, Siv; Kvalheim, Olav Martin; Arneberg, Reidar; Bårdsen, Kjetil; Hjelle, Anne; Ulvund, Martha J. (Peer reviewed; Journal article, 2013-11-14)
      Background: Classical scrapie in sheep is a fatal neurodegenerative disease associated with the conversion PrPC to PrPSc. Much is known about genetic susceptibility, uptake and dissemination of PrPSc in the body, but many ...
