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; Solvang, Stein-Erik Hafstad; Watne, Leiv (Peer reviewed; Journal article, 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 ... -
Investigating novel biomarkers of immune activation and modulation in the context of sedentary behaviour: a multicentre prospective ischemic stroke cohort study
Alme, Katinka Nordheim; Askim, Torunn; Assmus, Jörg; Mollnes, Tom Eirik; Naik, Mala; Næss, Halvor; Saltvedt, Ingvild; Ueland, Per-Magne; Ulvik, Arve; Knapskog, Anne-Brita (Peer reviewed; Journal article, 2021)Background Sedentary behaviour is associated with disease, but the molecular mechanisms are not understood. Valid biomarkers with predictive and explanatory properties are required. Therefore, we have investigated traditional ... -
Neopterin and kynurenic acid as predictors of stroke recurrence and mortality: a multicentre prospective cohort study on biomarkers of inflammation measured three months after ischemic stroke
Alme, Katinka Nordheim; Ulvik, Arve; Askim, Torunn; Assmus, Jörg; Mollnes, Tom Eirik; Naik, Mala; Næss, Halvor; Saltvedt, Ingvild; Ueland, Per-Magne; Knapskog, Anne Brita (Peer reviewed; Journal article, 2021)Background Chronic low-grade inflammation is associated with both ischemic stroke and sedentary behaviour. The aim of this study was to investigate the predictive abilities of biomarkers of inflammation and immune modulation ...
