Bacterial outer membrane vesicles engineered with lipidated antigens as a platform for Staphylococcus aureus vaccine

Significance Thanks to their potent built-in adjuvanticity, bacterial outer membrane vesicles (OMVs) represent an attractive vaccine platform. However, their full-blown exploitation relies on the availability of efficient engineering strategies. This work provides strong experimental evidence that OMVs can be successfully decorated with heterologous antigens by channeling them to the lipoprotein transport machinery. Not only did lipidated...
