      Ormerod, Monica Bettina E. Greenwood; Ueland, Thor; Werner, Maren Caroline Frogner; Hjell, Gabriela; Rødevand, Linn Nilsen; Sæther, Linn Sofie; Lunding, Synve Hoffart; Johansen, Ingrid Torp; Ueland, Torill; Lagerberg, Trine Vik; Melle, Ingrid; Djurovic, Srdjan; Andreassen, Ole; Steen, Nils Eiel (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-07-02)
      Background: Low-grade inflammation has been implicated in the pathophysiology of severe mental disorders (SMDs) and a link between immune activation and clinical characteristics is suggested. However, few studies have investigated how patterns across immune markers are related to diagnosis and illness course.<p > <p>Methods: A total of 948 participants with a diagnosis of schizophrenia (SCZ, N ...

    • Impulsivity across severe mental disorders: a cross-sectional study of immune markers and psychopharmacotherapy 

      Hjell, Gabriela; Rokicki, Jaroslav; Szabo, Attila; Holst, Rene; Tesli, Natalia; Bell, Christina; Fischer-Vieler, Thomas; Werner, Maren Caroline Frogner; Lunding, Synve Hoffart; Elkjær Greenwood Ormerod, Monica Bettina; Johansen, Ingrid Torp; Djurovic, Srdjan; Ueland, Thor; Andreassen, Ole; Melle, Ingrid; Lagerberg, Trine Vik; Mørch-Johnsen, Lynn Egeland; Steen, Nils Eiel; Haukvik, Unn Kristin Hansen (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-09-07)
      Background Impulsivity is a transdiagnostic feature linked to severe clinical expression and a potential target for psychopharmacological strategies. Biological underpinnings are largely unknown, but involvement of immune dysregulation has been indicated, and the efects of psychopharmacological agents vary. We investigated if impul‑ sivity was associated with circulating immune marker levels and ...

    • Interleukin-18 signaling system links to agitation in severe mental disorders 

      Hjell, Gabriela; Szabo, Attila; Mørch-Johnsen, Lynn Egeland; Holst, Rene; Tesli, Natalia; Bell, Christina; Fischer-Vieler, Thomas; Werner, Maren Caroline Frogner; Lunding, Synve Hoffart; Ormerod, Monica Bettina E. Greenwood; Johansen, Ingrid Torp; Dieset, Ingrid; Djurovic, Srdjan; Melle, Ingrid; Ueland, Thor; Andreassen, Ole; Steen, Nils Eiel; Haukvik, Unn Kristin Hansen (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-12)
      Objective: Agitation is a challenging clinical feature in severe mental disorders, but its biological correlates are largely unknown. Inflammasome-related abnormalities have been linked to severe mental disorders and implicated in animal models of agitation. We investigated if levels of circulating inflammasome-related immune markers were associated with agitation in severe mental disorders.<p> ...

    • Limited association between infections, autoimmune disease and genetic risk and immune activation in severe mental disorders 

      Werner, Maren Caroline Frogner; Wirgenes, Katrine Verena; Shadrin, Alexey; Lunding, Synve Hoffart; Rødevand, Linn; Hjell, Gabriela; Ormerod, Monica; Haram, Marit; Agartz, Ingrid; Djurovic, Srdjan; Melle, Ingrid; Aukrust, Pål; Ueland, Thor; Andreassen, Ole; Steen, Nils Eiel (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-19)
      Background: Low-grade inflammation may be part of the underlying mechanism of schizophrenia and bipolar disorder. We investigated if genetic susceptibility, infections or autoimmunity could explain the immune activation.<p> <p<Methods: Seven immune markers were selected based on indicated associations to severe mental disorders (IL1Ra, sIL-2R, IL-18, sgp130, sTNFR-1, APRIL, ICAM-1) and measured ...
