Outer membrane vesicles (OMVs) are spherical bilayered nanoparticles derived from the outer layer of Gram-negative bacteria. Bacteria communicate with nearby bacteria, their environment, and the cells of their host by secreting OMVs, which are essential for their survival. OMVs also play a critical role in bacterial pathogenesis since they are loaded with virulence factors, toxins, and enzymes. OMVs may modulate the immune response of the host by initiating inflammation through cytokine production and activating the innate immune response. OMVs also contribute to the resistance of bacteria to antibiotics by carrying antibiotic-degrading enzymes and acting as natural protection barriers. Concerns have also been raised regarding OMVs mediating the transfer of antibiotic resistance. Due to their advantageous properties, OMVs are attractive platforms for vaccine discovery and drug delivery research. In this review, we discuss the fundamental structure and biogenesis mechanisms of OMVs as well as their multifaceted roles in bacterial infection pathogenesis and host immune responses. We also discuss application examples of OMVs.
