Abstract:

Acute respiratory distress syndrome (ARDS), a fatal disease characterized by uncontrolled immune response and refractory hypoxemia, is most commonly induced by infection. Outer membrane vesicles (OMVs) are nanoparticles produced by gram-negative bacteria via the extrusion of the outer membrane and can deliver a range of bacterial molecules to host cells. Recently it was found that OMVs play vital roles in bacterial colonization, delivery of virulence factors, and disease pathogenesis. This article reviews the formation and biological functions of OMVs, and the inflammatory and pathological mechanisms of OMVs in ARDS.

Key words: Acute respiratory distress syndrome, Gram negative bacteria, Outer membrane vesicles, Immune response
