Bacterial AsmA Proteins Transfer Glycerophospholipids Between Membranes

Contact
Gram-negative bacteria are surrounded by inner and outer membranes whose glycerophospholipid building blocks are synthesized in the inner membrane and redistributed to the outer membrane by poorly understood mechanisms.

Bacteria‐Trained, MnO2‐Armored Dendritic Cells for Immunotherapy

Advanced Materials, EarlyView.
MnO2‐armored, bacteria‐trained dendritic cells undergo tumor‐responsive mechanical and immunological transformation. The nanocoating masks immune ligands and maintains a mechanically stiff, quiescent state during circulation, while the tumor microenvironment removes the armor and restores cellular deformability and immune accessibility.

Discovery of an archetypal protein transport system in bacterial outer membranes

Nature Structural & Molecular Biology, 2012
Bacteria have mechanisms to export proteins for diverse purposes, including colonization of hosts and pathogenesis. A small number of archetypal bacterial secretion machines have been found in several groups of bacteria and mediate a fundamentally distinct secretion process. Perhaps erroneously, proteins called 'autotransporters' have long been thought

Life‐Like Ferrous Oxide Microspheres from Kombucha

Advanced Materials Interfaces, EarlyView.
Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

Structural and functional studies of bacterial outer membrane lipopolysaccharide insertion and Schmallenberg virus replication [PDF]

, 2015
Lipopolysaccharide (LPS) is an essential component of the outer membrane (OM) of Gram-negative bacteria and plays a fundamental role in protecting the bacteria from harsh environments and toxic compounds.

A Critical Review on the Evolution of Chitosan‐Based Injectable Hydrogels in Bone Regeneration

Advanced Materials Interfaces, EarlyView.
The graphical illustration depicts hydrogel formulation using chitosan and biocompatible cross‐linkers, major advantages, and incorporation of cells, osteoinductive factors, and therapeutic drugs. Following injection, pH‐responsive gelation enables controlled drug release, promotes cell recruitment and osteogenic differentiation, enhances extracellular

Crosstalk between Helicobacter pylori and gastric epithelial cells is impaired by docosahexaenoic acid.

PLoS ONE, 2013
H. pylori colonizes half of the world's population leading to gastritis, ulcers and gastric cancer. H. pylori strains resistant to antibiotics are increasing which raises the need for alternative therapeutic approaches.
