    • Cerebrospinal fluid quinolinic acid is strongly associated with delirium and mortality in hip fracture patients 

      Watne, Leiv Otto; Pollmann, Christian Thomas; Neerland, Bjørn Erik; Quist-Paulsen, Else; Halaas, Nathalie Bodd; Idland, Ane-Victoria; Hassel, Bjørnar; Henjum, Kristi; Knapskog, Anne Brita; Frihagen, Frede; Ræder, Johan; Godø, Aasmund; Ueland, Per Magne; McCann, Adrian; Figved, Paul Wender; Selbæk, Geir; Zetterberg, Henrik; Fei Fang, Evandro; Myrstad, Marius; Giil, Lasse Melvær (Journal article; Peer reviewed, 2022)
      Background: The kynurenine pathway (KP) has been identified as a potential mediator linking acute illness to cognitive dysfunction by generating neuroactive metabolites in response to inflammation. Delirium (acute confusion) ...

    • Higher concentrations of kynurenic acid in CSF are associated with the slower clinical progression of Alzheimer's disease 

      Knapskog, Anne Brita; Aksnes, Mari; Edwin, Trine Holt; Ueland, Per Magne; Ulvik, Arve; Fang, Fei; Eldholm, Rannveig Sakshaug; Halaas, Nathalie Bodd; Saltvedt, Ingvild Tina; Giil, Lasse Melvær; Watne, Leiv (Journal article; Peer reviewed, 2023)
      Introduction: The kynurenine pathway's (KP) malfunction is closely related to Alzheimer's disease (AD), for antagonistic kynurenic acid (KA) and agonistic quinolinic acid act on the N-methyl-D-aspartate receptor, a possible ...

    • 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)
      Alterations in brain energy metabolism have long been proposed as one of several neurobiological processes contributing to delirium. This is supported by previous findings of altered CSF lactate and neuron-specific enolase ...

    • 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)
      The kynurenine pathway is implicated in aging, longevity, and immune regulation, but longitudinal studies and assessment of the cerebrospinal fluid (CSF) are lacking. We investigated tryptophan (Trp) and downstream kynurenine ...

    • Sex-specific associations of kynurenic acid with neopterin in Alzheimer’s disease 

      Knapskog, Anne-Brita; Edwin, Trine Holt; Ueland, Per Magne; Ulvik, Arve; Fang, Fei; Eldholm, Rannveig Sakshaug; Halaas, Nathalie Bodd; Solvang, Stein-Erik Hafstad; Saltvedt, Ingvild Tina; Watne, Leiv; Aksnes, Mari (Journal article; Peer reviewed, 2024-07-27)
      Background: Sex differences in neuroinflammation could contribute to women’s increased risk of Alzheimer’s disease (AD), providing rationale for exploring sex-specific AD biomarkers. In AD, dysregulation of the kynurenine ...
