Bacterial outer membrane vesicles and the host–pathogen interaction [PDF]

Genes & Development, 2005
Extracellular secretion of products is the major mechanism by which Gram-negative pathogens communicate with and intoxicate host cells. Vesicles released from the envelope of growing bacteria serve as secretory vehicles for proteins and lipids of Gram-negative bacteria.

Immunoinflammatory Mechanisms and Biocompatibility of Bioactive Dental Biomaterials: From Fundamental Insights to Clinical Translation

Advanced Healthcare Materials, EarlyView.
Surface‐host dialogue at the implant interface governs biological fate and osseointegration. Surface physicochemical properties of titanium (Ti) dental implants, including microgrooves, nanopatterns, nanotopography, roughness, and wettability, modulate the initial adsorption of proteins and the formation of a dynamic biointerface.

Bacterial Outer Membrane Vesicles and Immune Modulation of the Host

, 2023
This article reviews the role of outer membrane vesicles (OMVs) in mediating the interaction between Gram-negative bacteria and their human hosts. OMVs are produced by a diverse range of Gram-negative bacteria during infection and play a critical role in

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Bacterial Outer Membrane Vesicles Induce Plant Immune Responses

Molecular Plant-Microbe Interactions, 2016
Gram-negative bacteria continuously pinch off portions of their outer membrane, releasing membrane vesicles. These outer membrane vesicles (OMVs) are involved in multiple processes including cell-to-cell communication, biofilm formation, stress tolerance,

Hierarchical Structure and Fabrication of Functionally Graded Biointerfaces in the Mussel Byssus

Advanced Materials Interfaces, EarlyView.
The byssus is a fibrous protein‐based holdfast consisting of mechanically distinct interfaces, which mussels use to anchor their soft living tissue to hard seashore surfaces. Here, multiscale methodologies were used to elucidate the compositional and structural features underlying these functionally graded interfaces and how they are fabricated through

Outer membrane vesicles – offensive weapons or good Samaritans?

Journal of Oral Microbiology, 2015
Outer membrane vesicles (OMVs) from Gram-negative bacteria were first considered as artifacts and were followed with disbelief and bad reputation. Later, their existence was accepted and they became characterized as bacterial bombs, virulence bullets ...
