Super-Resolution Imaging of Protein Secretion Systems and the Cell Surface of Gram-Negative Bacteria

Frontiers in Cellular and Infection Microbiology, 2017
Gram-negative bacteria have a highly evolved cell wall with two membranes composed of complex arrays of integral and peripheral proteins, as well as phospholipids and glycolipids.

The Contribution of Membrane Vesicles to Bacterial Pathogenicity in Cystic Fibrosis Infections and Healthcare Associated Pneumonia

Frontiers in Microbiology, 2020
Almost all bacteria secrete spherical membranous nanoparticles, also referred to as membrane vesicles (MVs). A variety of MV types exist, ranging from 20 to 400 nm in diameter, each with their own formation routes.

Biogenesis of mitochondrial c-type cytochromes [PDF]

, 1990
Cytochromesc andc 1 are essential components of the mitochondrial respiratory chain. In both cytochromes the heme group is covalently linked to the polypeptide chain via thioether bridges. The location of the two cytochromes is in the intermembrane space;

Bacterial outer membrane vesicles suppress tumor by interferon-γ-mediated antitumor response

Nature Communications, 2017
Gram-negative bacteria actively secrete outer membrane vesicles, spherical nano-meter-sized proteolipids enriched with outer membrane proteins, to the surroundings.

Protective plant immune responses are elicited by bacterial outer membrane vesicles

bioRxiv, 2020
Bacterial outer membrane vesicles (OMVs) perform a variety of functions in bacterial survival and virulence. In mammalian systems, OMVs activate immune responses and have been exploited as vaccines.

Photo‐Controlled Antibacterial Drug Release From DASA‐Coated Silica Particles for Improved Treatment of Wound Infections

Advanced Functional Materials, EarlyView.
Synthesis and characterization of light‐responsive donor–acceptor Stenhouse adducts (DASA)‐coated chlorhexidine‐loaded silica nanoparticles. Such a controllable drug‐delivery system enables the release of the antimicrobial drug on demand and in consecutive cycles, thereby maintaining the concentration within the therapeutic window.

The Borrelia afzelii outer membrane protein BAPKO_0422 binds human Factor-H and is predicted to form a membrane-spanning beta-barrel [PDF]

, 2015
The deep evolutionary history of the Spirochetes places their branch point early in the evolution of the diderms, before the divergence of the present day Proteobacteria.

Inhibition of Pathogen Adhesion by Bacterial Outer Membrane-Coated Nanoparticles.

Angewandte Chemie, 2019
The treatment of bacterial infection is increasingly challenged by the rapid emergence of antibiotic resistance. Among various alternatives, anti-adhesion therapies that interfere with the bacterial adhesion to the host are attractive, as they avoid ...
