Antigen-specific acquired immunity in human brucellosis: implications for diagnosis, prognosis, and vaccine development. [PDF]

, 2012
Brucella spp., are Gram negative bacteria that cause disease by growing within monocyte/macrophage lineage cells. Clinical manifestations of brucellosis are immune mediated, not due to bacterial virulence factors.

Soft Ionic and Electronic Triboelectric Nanogenerators: Toward Attachable and Implantable Biomedical Applications

Advanced Materials, EarlyView.
This review provides an overview of triboelectric nanogenerator (TENG)–based biomedical applications by classifying studies into electronic and ionic systems across attachable and implantable platforms. It summarizes key material choices, device structures, and working mechanisms that characterize current TENG‐based research, and outlines six future ...

NIR‐Activated Ag2S Quantum Dots for Efficient Broad‐Spectrum Antibacterial and Biofilm Disruption

Advanced Materials Interfaces, EarlyView.
This study presents a novel non‐antibiotic strategy leveraging NIR‐activated Ag2S QDs for synergistic PTT/PDT. The platform degrades the protective extracellular matrix via localized hyperthermia, facilitating deep penetration and ROS‐induced oxidative damage.

Proteinaceous determinants of surface colonization in bacteria: Bacterial adhesion and biofilm formation from a protein secretion perspective

Frontiers in Microbiology, 2013
Bacterial colonization of biotic or abiotic surfaces results from two quite distinct physiological processes, namely bacterial adhesion and biofilm formation. Broadly speaking, a biofilm is defined as the sessile development of microbial cells.

A Novel Mechanism of Host-Pathogen Interaction through sRNA in Bacterial Outer Membrane Vesicles

PLoS Pathogens, 2016
Bacterial outer membrane vesicle (OMV)-mediated delivery of proteins to host cells is an important mechanism of host-pathogen communication. Emerging evidence suggests that OMVs contain differentially packaged short RNAs (sRNAs) with the potential to ...

Commensal bacterial outer membrane protein A induces interleukin-22 production

Cell Reports
Interleukin (IL)-22 promotes host-microbiota homeostasis. We sought to identify microbiota metabolite(s) that drive intestinal IL-22 production. We observed that exposing Peyer's patch cells (PPCs), ex vivo, to fecal supernatants (FSs) recapitulates fermentable fiber- and microbiota-dependent IL-22 production, and cellular sources thereof, thus ...

Comparison of bacterial intracellular and secreted proteins produced in milk versus medium for Escherichia coli by proteomic analysis

Journal of Dairy Science
: The growth and reproduction of microorganisms are dependent on nutrient supply. Here, milk and Luria-Bertani (LB) media were used as nutrition sources for Escherichia coli, and the changes in bacterial and secretory proteins at 3 time points (3, 9, and

Hydrogel Confinement Strategies for 3D Cell Culture in Microfluidic Systems

Advanced Materials Technologies, EarlyView.
Hydrogel confinement structures are key to organizing 3D cell cultures in microfluidic devices. This review classifies five structural strategies (micropillar, phaseguide, porous membrane, stepped‐height, and support‐free) and examines their trade‐offs alongside fabrication methods.

Discovery of new biosynthetic pathways: the lipid A story

Journal of Lipid Research, 2009
The outer monolayer of the outer membrane of Gram-negative bacteria consists of the lipid A component of lipopolysaccharide (LPS), a glucosamine-based saccharolipid that is assembled on the inner surface of the inner membrane.
