Cholesterol crystal-induced endothelial cell activation is complement-dependent and mediated by TNF
Nymo, Stig Haugset; Niyonzima, Nathalie; Espevik, Terje; Mollnes, Tom Eirik (Journal article; Peer reviewed, 2014)Cholesterol crystals are known to be a hallmark of atherosclerosis with recent studies demonstrating deposition of these crystals in early fatty streak formation as well as penetrating the intima following plaque rupture. ... -
Combined inhibition of complement and CD14 attenuates bacteria-induced inflammation in human whole blood more efficiently than antagonizing the toll-like receptor 4-MD2 complex
Gustavsen, Alice; Nymo, Stig Haugset; Landsem, Anne; Christiansen, Dorte; Ryan, Liv; Husebye, Harald; Lau, Corinna; Pischke, Søren Erik; Lambris, John D.; Espevik, Terje; Mollnes, Tom Eirik (Journal article; Peer reviewed, 2016)Background. Single inhibition of the Toll-like receptor 4 (TLR4)–MD2 complex failed in treatment of sepsis. CD14 is a coreceptor for several TLRs, including TLR4 and TLR2. The aim of this study was to investigate the effect ... -
Complement component 5 does not interfere with physiological hemostasis but is essential for Escherichia coli-induced coagulation accompanied by Toll-like receptor 4.
Landsem, Anne; Fure, Hilde; Ludviksen, Judith K; Christiansen, Dorte; Lau, Corinna; Mathisen, Monica Dammen; Bergseth, Grete; Nymo, Stig Haugset; Lappegård, Knut Tore; Woodruff, T. M.; Espevik, Terje; Mollnes, Tom Eirik; Brekke, Ole-Lars (Journal article; Peer reviewed, 2018)There is a close cross‐talk between complement, Toll‐like receptors (TLRs) and coagulation. The role of the central complement component 5 (C5) in physiological and pathophysiological hemostasis has not, however, been fully ... -
Human endothelial cell activation by Escherichia coli and staphylococcus aureus is mediated by TNF and IL-1β secondarily to activation of C5 and CD14 in whole blood
Nymo, Stig Haugset; Gustavsen, Alice; Nilsson, Per; Lau, Corinna; Espevik, Terje; Mollnes, Tom Eirik (Journal article; Peer reviewed, 2016)Endothelial cells (EC) play a central role in inflammation. E-selectin and ICAM-1 expression are essential for leukocyte recruitmentand are good markers of EC activation. Most studies of EC activation are done in vitro ... -
Inflammatory biomarkers are associated with aetiology and predict outcomes in community-acquired pneumonia: Results of a 5-year follow-up cohort study
Siljan, William Ward; Holter, Jan Cato; Michelsen, Annika; Nymo, Stig Haugset; Lauritzen, Trine; Oppen, Kjersti; Husebye, Einar; Ueland, Thor; Mollnes, Tom Eirik; Aukrust, Pål; Heggelund, Lars (Journal article; Peer reviewed, 2019)Background Biomarkers may facilitate clinical decisions in order to guide antimicrobial treatment and prediction of prognosis in community-acquired pneumonia (CAP). We measured serum C-reactive protein, procalcitonin (PCT) ... -
Properdin binding to complement activating surfaces depends on initial C3b deposition
Harboe, Morten; Johnson, Christina; Nymo, Stig Haugset; Ekholt, Karin; Schjalm, Camilla; Lindstad, Julie Katrine; Pharo, Anne Margrethe; Hellerud, Bernt C; Ekdahl, Kristina Nilsson; Mollnes, Tom Eirik; Nilsson, Per (Journal article; Peer reviewed, 2017)Two functions have been assigned to properdin; stabilization of the alternative convertase, C3bBb, is well accepted, whereas the role of properdin as pattern recognition molecule is controversial. The presence of ...
