Extracellular Vesicles from Different Pneumococcal Serotypes Are Internalized by Macrophages and Induce Host Immune Responses

Pathogens, 2021
Bacterial extracellular vesicles are membranous ultrastructures released from the cell surface. They play important roles in the interaction between the host and the bacteria.

Bacterial extracellular vesicles control murine norovirus infection through modulation of antiviral immune responses

Frontiers in Immunology, 2022
Human norovirus is the primary cause of non-bacterial gastroenteritis globally and is the second leading cause of diarrheal deaths in children in developing countries. However, effective therapeutics which prevent or clear norovirus infection are not yet

Tick extracellular vesicles enable arthropod feeding and promote distinct outcomes of bacterial infection

Nature Communications, 2021
Extracellular vesicles have been implicated in the transmission of pathogens from the arthropod to the human host. Here the authors show that tick-derived extracellular vesicles play a role in feeding and modulate the outcome of bacterial infection.

Systemically circulating bacterial extracellular vesicles: origin, fate, and function

Trends in Microbiology, 2022
Bacteria contribute to human host (patho)physiology through the production of a myriad of biomolecules enclosed in membrane vesicles [bacterial extracellular vesicles (BEVs)]. Recent research revealed that BEVs, as a functional output of bacteria, enter the systemic circulation.

Extracellular vesicles of the Gram-positive gut symbiont Bifidobacterium longum induce immune-modulatory, anti-inflammatory effects

npj Biofilms and Microbiomes, 2023
The gut microbiota is now well known to affect the host’s immune system. One way of bacterial communication with host cells is via the secretion of vesicles, small membrane structures containing various cargo.

Label-free relative quantitative proteomics reveals extracellular vesicles as a vehicle for Salmonella effector protein delivery

Frontiers in Microbiology, 2022
Extracellular vesicles are small vesicles with a diameter of 30–150 nm that are actively secreted by eukaryotic cells and play important roles in intercellular communication, immune responses, and tumorigenesis.

Outer membrane vesicles from bacteria: Role and potential value in the pathogenesis of chronic respiratory diseases

Frontiers in Cellular and Infection Microbiology, 2022
Infectious diseases are the leading cause of death in both adults and children, with respiratory infections being the leading cause of death. A growing body of evidence suggests that bacterially released extracellular membrane vesicles play an important ...

Bacterial Extracellular Vesicles in the Pathogenesis and Treatment of Liver Diseases. [PDF]

J Gastroenterol Hepatol
ABSTRACT Liver diseases represent a major global health challenge, yet current treatment options remain insufficient, highlighting the need for new therapeutic strategies. Recent research underscores the crucial role of the gut microbiota and their metabolites in liver disease progression.

Changes in the Murine Microbiome and Bacterial Extracellular Vesicle Production in Response to Antibiotic Treatment and Norovirus Infection

Viruses, 2023
Norovirus infection is influenced by the presence of commensal bacteria, and both human and murine norovirus (MNV) bind to these bacteria. These virus–bacterial interactions, as well as MNV infection, promote the increased production of bacterial ...
