Intracellular Symbiotic Bacteria Within Insects [PDF]

, 1999
Symbiosis is a permanent and hereditary association between two or more partners specifically distinct and, most of the time, very different from a phylogenetic point of view. A very common type of symbiosis involves bacteria, called endocytobiotes, living inside eukaryotic cells. Our investigation was limited to the endocytobiotes of insects.

Photothermal‐Activated Antibacterial Amyloid‐Polyphenol‐Iron Hydrogels for Synergistic Wound Healing

Advanced Healthcare Materials, EarlyView.
We report a thermally triggered supramolecular hydrogel (LTFe) formed by Fe3+ and tannic acid on lysozyme amyloid fibrils. Fe3+ enables rapid gelation and photothermal transduction with an efficiency of 88.56%. The LTFe hydrogel exhibits excellent biocompatibility, potent antibacterial activity against E. coli and S.

Intracellular habitat of pathogenic microorganisms: implications for antimicrobial chemotherapy

GMS Infectious Diseases, 2014
A few pathogenic bacteria have developed various strategies to live in particular intracellular compartments. Within such specific niches the conditions for antibiotic activities may be quite different from the milieu given in the laboratory for in ...

Functional Blood‐Brain Barrier Crossing by Biomimetic M13 Phage Vectors for Targeted Neuronal Delivery

Advanced Healthcare Materials, EarlyView.
This study investigates the M13 bacteriophage as a biomimetic nanovector capable of crossing in vitro models of the blood–brain barrier. By exploiting peculiar transcellular pathways, M13 avoids lysosomal degradation and preserves its structural integrity and functionality.

Enzyme-responsive peptide dendron nanoassemblies for targeting and eliminating intracellular drug-resistant bacteria

Nature Communications
Certain intracellular pathogens can reside within cells to evade host immune defenses and exhibit high tolerance to antibiotics. Current treatments for intracellular bacterial infections are limited by poor cellular penetration, inadequate targeting of ...

Cellular Exit Strategies of Intracellular Bacteria

Microbiology Spectrum, 2015
ABSTRACT The coevolution of intracellular bacteria with their eukaryotic hosts has presented these pathogens with numerous challenges for their evolutionary progress and survival. Chief among these is the ability to exit from host cells, an event that is fundamentally linked to pathogen dissemination and transmission.

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.
