Harnessing Innate Immunity - Complement and TLR Inhibition in Experimental Models of Gram Positive and Polymicrobial Bacteremia and Sepsis
(Doctoral thesis; Doktorgradsavhandling, 2017-11-28)Sepsis is a syndrome of life-threatening organ malfunction caused by a dysregulated host response to infection. The complement, kallikrein/kinin, coagulation and fibrinolysis plasma cascade systems as well as the TLR system recognize and initiate the immediate responses to infection and thus play an important role in the development of sepsis. In this regard, the ubiquitous TLR co-receptor, CD14, ... -

Consistent isotopic differences between Schistocephalus spp. parasites and their stickleback hosts
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-07-23)Parasite−host systems show markedly variable patterns in isotopic fractionation: parasites can be either depleted or enriched in 15N and 13C as compared to their hosts. However, it remains unknown whether isotopic fractionation patterns are similar in comparable parasite−host systems from markedly different ecosystems. Results of this study show that large-sized Schistocephalus spp. endoparasites ... -
