Novel type II toxin-antitoxin systems with VapD-like proteins

mBio
Type II toxin-antitoxin (TA) systems are widespread in prokaryotes. They consist of neighboring genes encoding two small proteins: a toxin that inhibits a critical cellular process and an antitoxin that binds to and neutralizes the toxin.

Detection of Clostridium tetani Neurotoxins Inhibited In Vivo by Botulinum Antitoxin B: Potential for Misleading Mouse Test Results in Food Controls

Toxins, 2018
The presence of botulinum neurotoxin-producing Clostridia (BPC) in food sources is a public health concern. In favorable environmental conditions, BPC can produce botulinum neurotoxins (BoNTs) outside or inside the vertebrate host, leading to ...

Structural Insights into Rational Design of Single-Domain Antibody-Based Antitoxins against Botulinum Neurotoxins

Cell Reports, 2020
Summary: Botulinum neurotoxin (BoNT) is one of the most acutely lethal toxins known to humans, and effective treatment for BoNT intoxication is urgently needed.

Performance of pyDock in 8th CAPRI: Energy‐Based Scoring Applied to Docking and AlphaFold Models

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The 8th CAPRI edition has shown a significant evolution in the field of protein–protein complex structure prediction. We have participated in all 11 targets proposed in this edition, involving domain‐domain, protein–protein, protein‐peptide, and protein‐DNA interactions, including homo‐ and hetero‐meric interfaces.

What is the link between stringent response, endoribonuclease encoding Type II Toxin-Antitoxin systems and persistence?

Frontiers in Microbiology, 2016
Persistence is a transient and non-inheritable tolerance to antibiotics by a small fraction of a bacterial population. One of the proposed determinants of bacterial persistence is toxin-antitoxin systems (TAS) which are also implicated in a wide range of

Diagnostic antibodies at an inflection point: From discovery platforms to design‐oriented engineering

VIEW, EarlyView.
This study systematically organizes the evolution of diagnostic antibodies from discovery platforms to design‐oriented engineering and analyzes the strengths and limitations of each approach. Meanwhile, it provides a critical, literature‐driven synthesis of current challenges, proposing integrated strategies for assay‐aware and function‐driven antibody

Oral Phageome as Potential Modulators of Periodontal Dysbiosis. A Systematic Review

Oral Diseases, EarlyView.
ABSTRACT Introduction The oral phageome, comprising bacteriophages inhabiting the oral cavity, has been proposed as a potential modulator of periodontal health and disease. This systematic review synthesizes current evidence on interactions between bacteriophages, key periodontal bacteria, and the host in periodontitis.

Development of an Innovative in Vitro Potency Assay for Anti-Botulinum Antitoxins

Toxins, 2016
Botulinum neurotoxins are bacterial proteins that cause botulism, a life-threatening disease. Therapy relies mostly on post-intoxication antibody treatment. The only accepted method to measure the potency of, and to approve, antitoxin preparations is the
