      Dongre, Mitesh; Singh, Bhupender; Aung, Kyaw Min; Larsson, Per; Miftakhova, Regina; Persson, Karina; Askarian, Fatemeh; Johannessen, Mona; Hofsten, Jonas von; Persson, Jenny L.; Erhardt, Marc; Tuck, Simon; Uhlin, Bernt Eric; Wai, Sun Nyunt (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-06-07)
      Using <i>Caenorhabditis elegans</i> as an infection host model for <i>Vibrio cholerae</i> predator interactions, we discovered a bacterial cytotoxin, MakA, whose function as a virulence factor relies on secretion via the flagellum channel in a proton motive force-dependent manner. The MakA protein is expressed from the polycistronic <i>makDCBA</i> (<i>m</i>otility-<i>a</i>ssociated <i>k</i>illing ...

    • Staphylococcus aureus Membrane-derived Vesicles Promote Bacterial Virulence and Confer Protective Immunity in Murine Infection Models 

      Askarian, Fatemeh; Lapek Jr., John D.; Dongre, Mitesh; Tsai, Chih-Ming; Kumaraswamy, Monika; Kousha, Armin; Valderrama, J. Andrés; Ludviksen, Judith K; Cavanagh, Jorunn Pauline; Uchiyama, Satoshi; Mollnes, Tom Eirik; Gonzalez, David J.; Wai, Sun Nyunt; Victor, Nizet; Johannessen, Mona (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-20)
      <i>Staphylococcus aureus</i> produces membrane-derived vesicles (MVs), which share functional properties to outer membrane vesicles. Atomic force microscopy revealed that <i>S. aureus</i>-derived MVs are associated with the bacterial surface or released into the surrounding environment depending on bacterial growth conditions. By using a comparative proteomic approach, a total of 131 and 617 proteins ...
