Circumventing Staphylococcus aureus subversion

Staphylococcus aureus subverts the host immune system with various mechanisms, including the cytolytic leukocidins. Chan et al. modified a protein scaffold to generate centryins, which bind S. aureus leukocidins in vitro and can protect human cells from leukocidin-mediated lysis. Further modification to extend centryin half-life in circulation led to antibacterial protection in various mouse models. These centryins could one day be used to prevent or possibly treat S. aureus infections in people.
