Unrelated toxin-antitoxin systems cooperate to induce persistence. [PDF]

open access: yes, 2015
Persisters are drug-tolerant bacteria that account for the majority of bacterial infections. They are not mutants, rather, they are slow-growing cells in an otherwise normally growing population.

The entry of diphtheria toxin into the mammalian cell cytoplasm: evidence for lysosomal involvement [PDF]

open access: yes, 1980
Lysosomotropic amines, such as ammonium chloride, are known to protect cells from the cytotoxic effects of diphtheria toxin. These drugs are believed to inhibit the transport of the toxin from a receptor at the cell exterior into the cytoplasm where a ...

The coevolution of toxin and antitoxin genes drives the dynamics of bacterial addiction complexes and intragenomic conflict [PDF]

open access: yes, 2012
Bacterial genomes commonly contain ‘addiction’ gene complexes that code for both a toxin and a corresponding antitoxin. As long as both genes are expressed, cells carrying the complex can remain healthy.

Production, Characterisation and Testing of an Ovine Antitoxin against Ricin; Efficacy, Potency and Mechanisms of Action

open access: yesToxins, 2017
Ricin is a type II ribosome-inactivating toxin that catalytically inactivates ribosomes ultimately leading to cell death. The toxicity of ricin along with the prevalence of castor beans (its natural source) has led to its increased notoriety and ...

An Auto-Regulating Type II Toxin-Antitoxin System Modulates Drug Resistance and Virulence in Streptococcus suis

open access: yesFrontiers in Microbiology, 2021
Toxin-antitoxin (TA) systems are ubiquitous genetic elements that play an essential role in multidrug tolerance and virulence of bacteria. So far, little is known about the TA systems in Streptococcus suis.

A case of asymmetric cranial nerve palsy due to iatrogenic botulism [PDF]

open access: yesAsia Pacific Journal of Medical Toxicology, 2021
Introduction:Botulism is a rare but lethal disease and atypical clinical presentations of this disease are difficult to diagnose. We report a case of iatrogenic botulism who presented withasymmetric cranial nerve involvement.Case report:An eighteen year ...

The mazEF toxin-antitoxin system as a novel antibacterial target in Acinetobacter baumannii [PDF]

open access: yes, 2014
Although analysis of toxin-antitoxin (TA) systems can be instructive, to date, there is no information on the prevalence and identity of TA systems based on a large panel of Acinetobacter baumannii clinical isolates.

Evaluating the Potential for Cross-Interactions of Antitoxins in Type II TA Systems

open access: yesToxins, 2020
The diversity of Type-II toxin–antitoxin (TA) systems in bacterial genomes requires tightly controlled interaction specificity to ensure protection of the cell, and potentially to limit cross-talk between toxin–antitoxin pairs of the same family of TA ...

The bacterial antitoxin HipB establishes a ternary complex with operator DNA and phosphorylated toxin HipA to regulate bacterial persistence [PDF]

open access: yes, 2014
Nearly all bacteria exhibit a type of phenotypic growth described as persistence that is thought to underlie antibiotic tolerance and recalcitrant chronic infections.

Chaperone addiction of toxin–antitoxin systems

open access: yesNature Communications, 2016
Some bacterial toxin-antitoxin systems consist of a labile antitoxin that inhibits a toxin, and a chaperone that stabilizes the antitoxin. Here, Bordes et al.
