Opportunities for engineering outer membrane vesicles using synthetic biology approaches

Abstract

Gram-negative bacteria naturally shed lipid vesicles, which contain complex molecular cargoes, from their outer membrane. These outer membrane vesicles (OMVs) have important biological functions relating to microbial stress responses, microbiome regulation, and host-pathogen interactions. OMVs are also attractive vehicles for delivering drugs, vaccines, and other therapeutic agents because of their ability to interact with host cells and their natural immunogenic properties. OMVs are also set to have a positive impact on other biotechnological and medical applications including diagnostics, bioremediation, and metabolic engineering. We envision that the field of synthetic biology offers a compelling opportunity to further expand and accelerate the foundational research and downstream applications of OMVs in a range of applications including the provision of OMV-based healthcare technologies. In our opinion, we discuss how current and potential future synergies between OMV research and synthetic biology approaches might help to further accelerate OMV research and real-world applications for the benefit of animal and human health.

Breaking the silence: The role of extracellular vesicles in unraveling the diagnosis and treatment of endometriosis

“…This evidence supports the idea that bacteria-derived-outer membrane vesicles (OMVs) could be a potential area of interest for endometriosis treatment manipulation and vaccine development. The most recent study unravels how bacteria-derived-OMVs can be engineered and exploited for therapy and vaccine development [123,124] .…”
