Biofilm Control by Active Topography with Mucin Coating

Advanced Functional Materials, EarlyView.
This study reports a new antifouling strategy based on a bioinspired design. Mucin coating enhances biofilm control by active topography with beating micron‐sized pillars. Besides the mechanical force of beating pillars, the antibiofilm activities also involve biological factors since mucin coating inhibits swarming motility and c‐di‐GMP synthesis in ...

High‐Resolution Patterned Delivery of Chemical Signals From 3D‐Printed Picoliter Droplet Networks

Advanced Materials, EarlyView.
3D‐printed picoliter droplet networks have been fabricated that control gene expression in bacterial populations by releasing chemical signals with precise spatial definition and high temporal resolution. This system of effector release is widely applicable, offering diverse applications in biology and medicine.

Phage-Encoded LuxR-Type Receptors Responsive to Host-Produced Bacterial Quorum-Sensing Autoinducers

mBio, 2019
Quorum sensing (QS) is a process of cell-to-cell communication that bacteria use to orchestrate collective behaviors. QS relies on the cell-density-dependent production, accumulation, and receptor-mediated detection of extracellular signaling molecules ...

Facile Fabrication of Antibacterial 3D Fibrous Sponge via In Situ Protonation‐Induced Direct Electrospinning

Advanced Materials Interfaces, EarlyView.
This work introduces a versatile and straightforward approach for directly fabricating electrospun 3D nanofibrous sponge using a selection of solvents, avoiding potentially toxic additives or additional steps. The most important novelty in this study is a one‐step electrospinning process that simultaneously imparts three‐dimensionality and ...

Identification of QuiP, the Product of Gene PA1032, as the Second Acyl-Homoserine Lactone Acylase of Pseudomonas aeruginosa PAO1 [PDF]

, 2006
The relevance of the acyl homoserine lactone (acyl-HSL) quorum signals N-3-oxododecanoyl-homoserine lactone (3OC12HSL) and N-butanoyl-homoserine lactone to the biology and virulence of Pseudomonas aeruginosa is well investigated.

Lysis, Lysogeny, and Virus-Microbe Ratios [PDF]

Nature, 2016
We show that neither the Piggyback-the-Winner model nor coral reef virome data presented in Knowles et al. [1] support a mechanistic link between increases in lysogeny, suppression of lysis, and the decline of the virus-to-microbial cell ratio (VMR) at high microbial cell densities across environmental and human-associated systems.

An Insect Salivary Sheath Protein Triggers Plant Resistance to Insects and Pathogens as a Conserved HAMP

Advanced Science, EarlyView.
The salivary sheath protein myosin from SBPH is critical for the formation of the salivary sheath and feeding. However, myosin functions as a HAMP and triggered plant BAK1‐mediated PTI responses, which include the activation of calcium signaling pathways, MAPK phosphorylation, ROS bursts, and cell death, thereby triggering JA pathway.

Structural and Biochemical Characterization of a Widespread Enterobacterial Peroxidase Encapsulin

Advanced Science, EarlyView.
Encapsulins are self‐assembling bacterial protein compartments loaded with cargo enzymes. The most abundant encapsulin cargo class are Dye‐decolorizing Peroxidases (DyPs). In this study, we structurally and biochemically characterize a DyP encapsulin found in many enterobacteria.
