      The recently discovered lytic polysaccharide monooxygenases (LPMOs), which cleave polysaccharides by oxidation, have been associated with bacterial virulence, but supporting functional data is scarce. Here we show that CbpD, the LPMO of <i>Pseudomonas aeruginosa</i>, is a chitin-oxidizing virulence factor that promotes survival of the bacterium in human blood. The catalytic activity of CbpD was ...

      Wyller, Vegard Brunn; Ngyuen, Chinh Bkrong; Ludviksen, Judith Anita; Mollnes, Tom Eirik (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-12-04)
      <i>Background</i>: Chronic fatigue syndrome (CFS) is a prevalent and disabling condition among adolescent. The disease mechanisms are unknown. Previous studies have suggested elevated plasma levels of several cytokines, but a recent meta-analysis of 38 articles found that of 77 diferent cytokines measured in plasma, transforming growth factor beta (TGF-β) was the only one that was elevated in patients ...
