Role of Bacterial Extracellular Vesicles in Manipulating Infection
Infection and Immunity, 2023Mammalian-cell-derived extracellular vesicles, such as exosomes, have been a key focal point for investigating host-pathogen interactions and are major facilitators in modulating both bacterial and viral infection. However, in recent years, increasing attention has been given to extracellular vesicles produced by bacteria and the role they play in ...

Bacterial extracellular vesicles and their interplay with the immune system
Pharmacology & Therapeutics, 2023The mammalian intestinal tract harbors trillions of microorganisms confined within this space by mucosal barriers. Despite these barriers, bacterial components may still be found elsewhere in the body, even in healthy subjects. Bacteria can release small lipid-bound particles, also named bacterial extracellular vesicles (bEV). While bacteria themselves

Stochastic effects in bacterial communication mediated by extracellular vesicles
Physical Review E, 2023Quorum sensing (QS) allows bacterial cells to sense changes in local cell density and, hence, to regulate multicellular processes, including biofilm formation, regulation of virulence, and horizontal gene transfer. While, traditionally, QS was thought to involve the exchange of extracellular signal molecules free in solution, recent experiments have ...

Bacterial extracellular vesicles: Emerging nanoplatforms for biomedical applications
Microbial Pathogenesis, 2023Bacterial extracellular vesicles (BEVs) are nanosized lipid bilayers generated from membranes that are filled with components derived from bacteria. BEVs are important for the physiology, pathogenicity, and interactions between bacteria and their hosts as well. BEVs represent an important mechanism of transport and interaction between cells.

Engineered bacterial extracellular vesicles for gastrointestinal diseases
Journal of Controlled ReleaseThe gut microbiota, a complex microbial ecosystem within the gastrointestinal (GI) tract, plays a pivotal role in maintaining GI homeostasis. Dysbiosis of this community is increasingly implicated in the pathogenesis of diverse GI disorders. Bacterial extracellular vesicles (bEVs) secreted from gut microbes have emerged as an innovative therapeutic ...

Bacterial extracellular vesicles in biofluids as potential diagnostic biomarkers
Expert Review of Molecular Diagnostics, 2022Extracellular vesicles (EVs) are spherical membrane-derived lipid bilayers released by cells. The human microbiota consists of trillions of microorganisms, with bacteria being the largest group secreting microbial EVs. The discovery of bacterial EVs (BEVs) has garnered interest among researchers as potential diagnostic markers, given that the ...

Bacterial extracellular vesicles and their associated toxins
2023Bacterial extracellular vesicles (BEV) are spherical nanostructures released by all bacteria and play vital roles in cell communication. In disease-causing bacteria, the release of BEVs can further help with the infection by delivering toxins and virulence factors into host cells.

Isolation and Proteomic Characterization of Bacterial Extracellular Membrane Vesicles
Current Protein & Peptide Science, 2014The secretion of extracellular membrane vesicles (EMVs) is a common phenomenon that occurs in archaea, bacteria, and mammalian cells. EMVs contain biologically active proteins, which have diverse roles in biological processes. The outer membrane vesicles (OMVs) of Gram-negative bacteria and membrane vesicles (MVs) of Gram-positive bacteria have been ...

Isolation of Bacterial Extracellular Vesicles and Identification of Their Protein Cargo
2023Bacterial membrane vesicles (BMVs) are important effectors in the pathogenesis, virulence, and biofilm formation during different bacterial infections. Because of their structure, BMVs can be applied as drug delivery systems (DDS) or in the production of immunogenic vaccines against different untreated diseases.
