• Dynamics of immune effector mechanisms during infection with Mycobacterium aviumin C57BL/6 mice 

      Haug, Markus; Awuh, Jane Atesoh; Steigedal, Magnus; Kojen, June Frengen; Marstad, Anne; Nordrum, Ivar Skjåk; Halaas, Øyvind; Flo, Trude Helen (Journal article; Peer reviewed, 2013)
      Opportunistic infections with non-tuberculous mycobacteria such as Mycobacterium avium are receiving renewed attention because of increased incidence and difficulties in treatment. As for other mycobacterial infections, a ...
    • Genetic Variation/Evolution and Differential Host Responses Resulting from In-Patient Adaptation of Mycobacterium avium 

      Kannan, Nisha; Lai, Yi-Pin; Haug, Markus; Lilleness, M.K.; Bakke, Siril Skaret; Marstad, Anne; Hov, Håkon; Naustdal, Thor; Afset, Jan Egil; Ioerger, Thomas R.; Flo, Trude Helen; Steigedal, Magnus (Journal article; Peer reviewed, 2019)
      Members of the Mycobacterium avium complex (MAC) are characterized as nontuberculosis mycobacteria and are pathogenic mainly in immunocompromised individuals. MAC strains show a wide genetic variability, and there is growing ...
    • Global Assessment of Mycobacterium avium subsp. hominissuis Genetic Requirement for Growth and Virulence 

      Dragset, Marte Singsås; Ioerger, Thomas R.; Loevenich, Maja; Haug, Markus; Sivakumar, Niruja; Marstad, Anne; Cardona, Pere-Joan; Klinkenberg, Geir; Rubin, Eric J.; Steigedal, Magnus; Flo, Trude Helen (Journal article; Peer reviewed, 2019)
      Nontuberculous mycobacterial infections caused by the opportunistic pathogen Mycobacterium avium subsp. hominissuis (MAH) are currently receiving renewed attention due to increased incidence combined with difficult treatment. ...
    • Lipocalin 2 imparts selective pressure on bacterial growth in the bladder and is elevated in women with urinary tract infection 

      Steigedal, Magnus; Marstad, Anne; Haug, Markus; Damås, Jan Kristian; Strong, Roland K.; Roberts, Pacita L.; Himpsl, Stephanie D.; Stapleton, Ann; Hooton, Thomas M.; Mobley, Harry L.T.; Hawn, Thomas R.; Flo, Trude Helen (Journal article; Peer reviewed, 2014)
      Competition for iron is a critical component of successful bacterial infections, but the underlying in vivo mechanisms are poorly understood. We have previously demonstrated that lipocalin 2 (LCN2) is an innate immunity ...
    • Plasma membrane damage causes NLRP3 activation and pyroptosis during Mycobacterium tuberculosis infection 

      Beckwith, Kai Sandvold; Beckwith, Marianne Sandvold; Ullmann, Sindre; Sætra, Ragnhild Sofie Ragnhildstveit; Kim, Haelin; Marstad, Anne; Åsberg, Signe Elisabeth; Strand, Trine Aakvik; Haug, Markus; Niederweis, Michael; Stenmark, Harald Alfred; Flo, Trude Helen (Peer reviewed; Journal article, 2020)
      Mycobacterium tuberculosis is a global health problem in part as a result of extensive cytotoxicity caused by the infection. Here, we show how M. tuberculosis causes caspase-1/NLRP3/gasdermin D-mediated pyroptosis of human ...
