• Air Bubbles Activate Complement and Trigger Hemostasis and C3-Dependent Cytokine Release Ex Vivo in Human Whole Blood 

      Storm, Benjamin; Christiansen, Dorte; Fure, Hilde; Ludviksen, Judith K; Lau, Corinna; Lambris, John D.; Woodruff, Trent M.; Brekke, Ole-Lars; Braaten, Tonje Bjørndal; Nielsen, Erik Waage; Mollnes, Tom Eirik (Journal article; Peer reviewed, 2021)
      Venous air embolism, which may complicate medical and surgical procedures, activates complement and triggers thromboinflammation. In lepirudin-anticoagulated human whole blood, we examined the effect of air bubbles on ...
    • Cholesterol Crystals Induce coagulation Activation through Complement-Dependent Expression of Monocytic Tissue Factor 

      Gravastrand, Caroline S.; Steinkjer, Bjørg; Halvorsen, Bente; Landsem, Anne; Skjelland, Mona; Jacobsen, Eva Astrid; Woodruff, Trent M.; Lambris, John D.; Mollnes, Tom Eirik; Brekke, Ole-Lars; Espevik, Terje; Rokstad, Anne Mari (Journal article; Peer reviewed, 2019)
      Cholesterol crystals (CC) are strong activators of complement and could potentially be involved in thromboinflammation through complement-coagulation cross-talk. To explore the coagulation-inducing potential of CC, we ...
    • In vitro evaluation of iron oxide nanoparticle-induced thromboinflammatory response using a combined human whole blood and endothelial cell model 

      Gerogianni, Alexandra; Bal, Melissa; Mohlin, Camilla; Woodruff, Trent M.; Lambris, John D.; Mollnes, Tom Eirik; Sjöström, Dick J.; Nilsson, Per (Peer reviewed; Journal article, 2023)
      Iron oxide nanoparticles (IONPs) are widely used in diagnostic and therapeutic settings. Upon systemic administration, however, they are rapidly recognized by components of innate immunity, which limit their therapeutic ...
    • Mitochondrial C5aR1 activity in macrophages controls IL-1β production underlying sterile inflammation 

      Niyonzima, Nathalie; Rahman, Jubayer; Kunz, Natalie; West, Erin; Freiwald, Tilo; Desai, Jigar V.; Merle, Nicolas; Gidon, Alexandre; Sporsheim, Bjørnar; Lionakis, Michail S.; Evensen, Kristin; Lindberg, Beate; Skagen, Karolina; Skjelland, Mona; Singh, Parul; Haug, Markus; Ruseva, Marieta M.; Kolev, Martin; Bibby, Jack; Marshall, Olivia; O’Brien, Brett; Deeks, Nigel; Afzali, Behdad; Clark, Richard J.; Woodruff, Trent M.; Pryor, Mylton; Yang, Zhi-Hong; Remaley, Alan T.; Mollnes, Tom Eirik; Hewitt, Stephen M.; Yan, Bingyu; Kazemian, Majid; Kiss, Mate G.; Binder, Christoph J.; Halvorsen, Bente; Espevik, Terje; Kemper, Claudia (Peer reviewed; Journal article, 2021)
      While serum-circulating complement destroys invading pathogens, intracellularly active complement, termed the “complosome,” functions as a vital orchestrator of cell-metabolic events underlying T cell effector responses. ...
    • Staphylococcus aureus-induced complement activation promotes tissue factor-mediated coagulation 

      Skjeflo, Espen Waage; Christiansen, Dorte; Fure, Hilde; Ludviksen, Judith K; Woodruff, Trent M.; Espevik, Terje; Nielsen, Erik Waage; Brekke, Ole-Lars; Mollnes, Tom Eirik (Journal article; Peer reviewed, 2018)
      Background There is extensive cross‐talk between the complement system, the Toll‐like receptors (TLRs), and hemostasis. Consumptive coagulopathy is a hallmark of sepsis, and is often mediated through increased tissue ...
    • Synthetic Oligodeoxynucleotide CpG Motifs Activate Human Complement through Their Backbone Structure and Induce Complement-Dependent Cytokine Release 

      de Boer, Eline; Sokolova, Marina; Quach, Huy Quang; Mc Adam, Karin Ekholt; Götz, Maximilian P.; Chaban, Viktoriia; Vaage, Ingvar Jarle; Fageräng, Beatrice Linnea Christina; Woodruff, Trent M.; Garred, Peter; Nilsson, Per; Mollnes, Tom Eirik; Pischke, Soeren (Peer reviewed; Journal article, 2022)
      Bacterial and mitochondrial DNA, sharing an evolutionary origin, act as danger-associated molecular patterns in infectious and sterile inflammation. They both contain immunomodulatory CpG motifs. Interactions between CpG ...
    • Thrombin Differentially Modulates the Acute Inflammatory Response to Escherichia coli and Staphylococcus aureus in Human Whole Blood 

      Johnson, Christina; Quach, Huy Quang; Lau, Corinna; Ekholt, Karin; Espevik, Terje; Woodruff, Trent M.; Pischke, Soeren; Mollnes, Tom Eirik; Nilsson, Per (Peer reviewed; Journal article, 2022)
      Thrombin plays a central role in thromboinflammatory responses, but its activity is blocked in the common ex vivo human whole blood models, making an ex vivo study of thrombin effects on thromboinflammatory responses ...
