Outer Membrane Vesicles of Gram-Negative Bacteria: An Outlook on Biogenesis

Front Microbiol. 2021 Mar 4:12:557902. doi: 10.3389/fmicb.2021.557902. eCollection 2021.

Abstract

Outer membrane vesicles (OMVs) from Gram-negative bacteria were first described more than 50 years ago. However, the molecular mechanisms involved in biogenesis began to be studied only in the last few decades. Presently, the biogenesis and molecular mechanisms for their release are not completely known. This review covers the most recent information on cellular components involved in OMV biogenesis, such as lipoproteins and outer membrane proteins, lipopolysaccharide, phospholipids, quorum-sensing molecules, and flagella.

Keywords: LPS; OMVs biogenesis; PQS; bacterial vesicles; extracellular vesicles; flagellin; outer membrane vesicles; phospholipids.
