      van Os, Elise Anne; Cools, Laura; Eysackers, Nathalie; Szafranska, Karolina; Smout, Ayla; Verhulst, Stefaan; Reynaert, Hendrik; McCourt, Peter Anthony; Mannaerts, Inge; van Grunsven, Leo A. (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-28)
      Chronic liver disease can lead to liver fibrosis and ultimately cirrhosis, which is a significant health burden and a major cause of death worldwide. Reliable in vitro models are lacking and thus mono-cultures of cell lines are still used to study liver disease and evaluate candidate anti-fibrotic drugs. We established functional multicellular liver spheroid (MCLS) cultures using primary mouse ...

    • SLE classification criteria: Science-based icons or algorithmic distractions – an intellectually demanding dilemma 

      Rekvig, Ole Petter (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-28)
      It is, so to say, not a prerogative authority assigned to SLE classification criteria that allow them to declare something definitively important about SLE. This is particularly true as criteria-based classification processes overrule the highly needed evolution of concise diagnostic criteria. It is classification criteria that allocate SLE patients into cohorts intended to describe the nature of ...
