Transmembrane helix dynamics of bacterial chemoreceptors supports a piston model of signalling. [PDF]

, 2011
Transmembrane α-helices play a key role in many receptors, transmitting a signal from one side to the other of the lipid bilayer membrane. Bacterial chemoreceptors are one of the best studied such systems, with a wealth of biophysical and mutational data

Molecular Aspects of Secretory Granule Exocytosis by Neurons and Endocrine Cells [PDF]

, 1994
Neuronal communication and endocrine signaling are fundamental for integrating the function of tissues and cells in the body. Hormones released by endocrine cells are transported to the target cells through the circulation.

Contribution of Membrane Vesicle to Reprogramming of Bacterial Membrane Fluidity in Pseudomonas aeruginosa

mSphere, 2022
Pseudomonas aeruginosa is an opportunistic pathogen capable of resisting environmental insults by applying various strategies, including regulating membrane fluidity and producing membrane vesicles (MVs).

Solution nuclear magnetic resonance spectroscopy of bacterial outer membrane proteins in natively excreted vesicles using engineered Escherichia coli

MicrobiologyOpen, 2022
Gaining structural information on membrane proteins in their native lipid environment is a long‐standing challenge in molecular biology. Instead, it is common to employ membrane mimetics, which has been shown to affect protein structure, dynamics, and ...

Roles of bacterial extracellular vesicles in systemic diseases

Frontiers in Microbiology, 2023
Accumulating evidence suggests that in various systems, not all bidirectional microbiota–host interactions involve direct cell contact. Bacterial extracellular vesicles (BEVs) may be key participants in this interkingdom crosstalk.

Bacterial membrane vesicle and its diversity

Drug Delivery System, 2021
すべての生物において細胞外小胞の存在が確認されている。その細胞外小胞の形成機構とともにその役割や生理的機能が近年ますます注目されてきている。細菌の細胞外小胞の形成には細胞死が関わり、それにより細胞外小胞の多様性が生まれることが明らかになった。

A bacterial membrane sculpting protein with BAR domain-like activity

eLife, 2021
Bin/Amphiphysin/RVS (BAR) domain proteins belong to a superfamily of coiled-coil proteins influencing membrane curvature in eukaryotes and are associated with vesicle biogenesis, vesicle-mediated protein trafficking, and intracellular signaling. Here, we

Cochleates derived from Vibrio cholerae O1 proteoliposomes : The impact of structure transformation on mucosal immunisation [PDF]

, 2012
Cochleates are phospholipid-calcium precipitates derived from the interaction of anionic lipid vesicles with divalent cations. Proteoliposomes from bacteria may also be used as a source of negatively charged components, to induce calcium-cochleate ...

Proteome profiling of secreted and membrane vesicle associated proteins of an invasive and a commensal Staphylococcus haemolyticus isolate

Data in Brief, 2019
Bacterial membrane vesicles (MVs) mediate bacterial virulence by enabling secretion and long distance delivery of bacterial effector molecules. Staphylococcus haemolyticus has now been demonstrated to produce membrane vesicles (MVs).

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.
