      Background & Aims Primary sclerosing cholangitis (PSC) is a progressive liver disease characterised by fluctuating liver biochemistries and highly variable disease progression. The Enhanced Liver Fibrosis (ELF®) test and ...
    • GPCR-specific autoantibody signatures are associated with physiological and pathological immune homeostasis 

      Cabral-Marques, Otavio; Marques, Alexandre; Melvær, Giil Lasse; De Vito, Roberta; Rademacher, Judith; Günther, Jeannine; Lange, Tanja; Humrich, Jens; Klapa, Sebastian; Schinke, Susanne; Schimke, Lena; Marschner, Gabriele; Pitann, Silke; Adler, Sabine; Dechend, Ralf; Muller, Dominik N.; Braicu, Ioana; Sehouli, Jalid; Schulze-Forster, Kai; Trippel, Tobias; Scheibenbogen, Carmen; Staff, Anne Cathrine; Mertens, Peter; Löbel, Madlen; Mastroianni, Justin; Plattfaut, Corinna; Gieseler, Frank; Dragun, Duska; Engelhardt, Barbara Elizabeth; Fernandez-Cabezudo, Maria; Ochs, Hans D; Al-Ramadi, Basel K; Lamprecht, Peter; Mueller, Antje; Heidecke, Harald; Riemekasten, Gabriela (Peer reviewed; Journal article, 2018-12-06)
      Autoantibodies have been associated with autoimmune diseases. However, studies have identified autoantibodies in healthy donors (HD) who do not develop autoimmune disorders. Here we provide evidence of a network of ...
    • Impaired glucose utilization in the brain of patients with delirium following hip fracture 

      Titlestad, Irit; Watne, Leiv; Caplan, Gideon A.; McCann, Adrian; Ueland, Per Magne; Neerland, Bjørn Erik; Myrstad, Marius; Halaas, Nathalie Bodd; Pollmann, Christian Thomas; Henjum, Kristi; Ranhoff, Anette Hylen; Solberg, Lene Bergendal; Figved, Wender; Cunningham, Colm; Melvær, Giil Lasse (Journal article; Peer reviewed, 2024)

    • Kynurenine Pathway Metabolites in the Blood and Cerebrospinal Fluid Are Associated with Human Aging 

      Solvang, Stein-Erik Hafstad; Hodge, Allison; Watne, Leiv; Cabral-Marques, Otavio; Nordrehaug, Jan Erik; Giles, Graham G.; Dugué, Pierre-Antoine; Nygård, Ottar Kjell; Ueland, Per Magne; McCann, Adrian; Idland, Ane-Victoria; Midttun, Øivind; Ulvik, Arve; Halaas, Nathalie Bodd; Tell, Grethe S.; Melvær, Giil Lasse (Journal article; Peer reviewed, 2022)
