(Peer reviewed; Journal article, 2022)
      Background: Venous thromboembolism (VTE) is a life-threatening vascular event with environmental and genetic determinants. Recent VTE genome-wide association studies (GWAS) meta-analyses involved nearly 30 000 VTE cases ...

      Background: Experimental studies have shown that the complement activating enzyme MASP-2 (mannose-binding lectin associated serine protease 2) exhibits a thrombin-like activity and that inhibition of MASP-2 protects ...

    • High plasma levels of C1-inhibitor are associated with lower risk of future venous thromboembolism 

      Grover, Steven P.; Snir, Omri; Hindberg, Kristian Dalsbø; Englebert, Tatianna M.; Brækkan, Sigrid Kufaas; Morelli, Vania Maris; Jensen, Søren Beck; Wolberg, Alisa S.; Mollnes, Tom Eirik; Ueland, Thor; Mackman, Nigel; Hansen, John Bjarne (Peer reviewed; Journal article, 2023)
