Outer Membrane Vesicles of Gram-Negative Bacteria: An Outlook on Biogenesis ; Frontiers in Microbiology

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. ; CONACYTConsejo Nacional de Ciencia y Tecnologia (CONACyT) [61529]; SIP-IPN [20182152, 20195737, 20200594]; SAGARPA-CONACYTConsejo Nacional de Ciencia y Tecnologia (CONACyT) [2017-02-291311]; PIFI-IPN scholarships; COFAA-IPN; SIP-EDI; SNI-CONACYTConsejo Nacional de Ciencia y Tecnologia (CONACyT) ; This work was funded by CONACYT 61529, SIP-IPN 20182152, 20195737, 20200594, and SAGARPA-CONACYT 2017-02-291311.
