Recognition of extracellular DNA by type IV pili promotes biofilm formation by \u3ci\u3eClostridioides difficile\u3c/i\u3e [PDF]

, 2022
Clostridioides difficile is a Gram-positive bacillus, which is a frequent cause of gastrointestinal infections triggered by the depletion of the gut microbiome. Because of the frequent recurrence of these infections after antibiotic treatment, mechanisms

Optically Tunable Threshold Switching and Thermally Activated Transport in Planar Ag/MAPbI3 Thin Single‐Crystal Devices

Advanced Science, Volume 13, Issue 60, 28 October 2026.
Planar Ag/MAPbI3 thin single‐crystal halide perovskite devices show ultralow dark current and optically tunable threshold switching. Illumination enhances the polarity‐dependent hysteresis and shifts the switching voltage, whereas temperature‐dependent measurements reveal thermally activated, contact‐limited transport, underscoring the central role of ...

Screening of a Haloferax volcanii Transposon Library Reveals Novel Motility and Adhesion Mutants

Life, 2016
Archaea, like bacteria, use type IV pili to facilitate surface adhesion. Moreover, archaeal flagella—structures required for motility—share a common ancestry with type IV pili.

Engineering Hierarchical Graphene Hydrogels for Microbial Fuel Cells

Advanced Energy and Sustainability Research, Volume 7, Issue 10, October 2026.
This study reveals the crucial trade‐off between electrical conductivity and biocompatibility in hierarchical graphene hydrogels for microbial fuel cells. By optimizing hydrothermal synthesis conditions, the engineered bioanodes achieve a delicate balance that maximizes extracellular electron transfer.

Interactions between pili affect the outcome of bacterial competition driven by the type VI secretion system [PDF]

The bacterial type VI secretion system (T6SS) is a widespread, kin-discriminatory weapon capable of shaping microbial communities. Due to the system’s dependency on contact, cellular interactions can lead to either competition or kin protection.

Meningococci drive host membrane tubulation to recruit their signaling receptors

Nature Communications
Once passed into the bloodstream, bacterial pathogens have a limited time to interact with permissive receptors at the surface of host cells. Neisseria meningitidis has developed an extremely effective strategy allowing it to find its receptors in a few ...

Cooperative retraction of bundled type IV pili enables nanonewton force generation.

PLoS Biology, 2008
The causative agent of gonorrhea, Neisseria gonorrhoeae, bears retractable filamentous appendages called type IV pili (Tfp). Tfp are used by many pathogenic and nonpathogenic bacteria to carry out a number of vital functions, including DNA uptake ...

Immunoinformatics‐Based Design of a Multi‐Epitope Vaccine Targeting a Conserved Copper–Associated Protein in Neisseria gonorrhoeae

Biotechnology and Applied Biochemistry, Volume 73, Issue 5, Page 2373-2387, October 2026.
ABSTRACT Neisseria gonorrhoeae poses an urgent public health challenge due to rapidly increasing antimicrobial resistance and the absence of an effective vaccine. Targeting conserved bacterial pathways involved in essential physiological processes may provide new opportunities for vaccine antigen discovery.
