Control of pili synthesis and putrescine homeostasis in Escherichia coli

eLife
Polyamines are biologically ubiquitous cations that bind to nucleic acids, ribosomes, and phospholipids and, thereby, modulate numerous processes, including surface motility in Escherichia coli.

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

Biotechnology and Applied Biochemistry, EarlyView.
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.

Extrapolation strategy matters when transferring ecological niche models: new visualization tools for informed decisions

Ecography, EarlyView.
Abstract Ecological niche models (ENMs) are commonly used to predict species' potential distributions across space and time, allowing researchers and practitioners to assess invasion risk, estimate the impacts of future climate change, and reconstruct past distributions.

Critical roles of a housekeeping sortase of probiotic Bifidobacterium bifidum in bacterium–host cell crosstalk

iScience, 2021
Summary: Bifidobacterium bifidum YIT 10347 (BF-1) is adhesive in vitro. Here we studied the molecular aspects of the BF-1 adhesion process. We identified and characterized non-adhesive mutants and found that a class E housekeeping sortase was critical ...

Selective Binding of Mannose-Encapsulated Gold Nanoparticles to Type 1 Pili in Escherichia coli [PDF]

Journal of the American Chemical Society, 2002
The synthesis, characterization and biological application of mannose encapsulated gold nanoparticles (m-AuNP) are reported. m-AuNP is well dispersed and very stable without aggregation in the media of broad ion strength and pH ranges. The selective binding of m-AuNP to the mannose adhesin FimH of bacterial type 1 pili is demonstrated using ...

A Comprehensive Study of Bidirectional Interactions Between the Human Microbiome and Blood Malignancies and Hematologic Conditions: Focus on Novel Therapeutic Strategies

Journal of Clinical Laboratory Analysis, EarlyView.
Microbiota‐targeted therapeutic strategies in hematological disorders. aHSCT: Transplanted immune cells from the donor may attack the recipient's tissues, especially when damage to the intestinal epithelium disrupts the gut microbiota, contributing to GVHD. Maintaining a balanced gut microbiota that supports immune regulation helps reduce GVHD risk and

Sinorhizobium meliloti GR4 Produces Chromosomal- and pSymA-Encoded Type IVc Pili That Influence the Interaction with Alfalfa Plants

Plants
Type IVc Pili (T4cP), also known as Tad or Flp pili, are long thin microbial filaments that are made up of small-sized pilins. These appendages serve different functions in bacteria, including attachment, biofilm formation, surface sensing, motility, and

Purification and chemical characterization of type 1 pili isolated from Klebsiella pneumoniae.

Journal of Biological Chemistry, 1982
Type 1 pili were purified from a Klebsiella pneumoniae strain isolated from a human urinary tract infection. The pili were removed from the bacteria by mechanical shearing, precipitated out of solution by ammonium sulfate, solubilized in a deoxycholate-containing buffer, and finally purified by gel filtration.
