Toxin–antitoxin (TA) systems are widespread bacterial immune systems that confer protection against various environmental stresses. TA systems have been classified into eight types (I–VIII) based on the nature and mechanism of action of the antitoxin ...

Shaping Pulses to Control Bistable Monotone Systems Using Koopman Operator [PDF]
In this paper, we further develop a recently proposed control method to switch a bistable system between its steady states using temporal pulses. The motivation for using pulses comes from biomedical and biological applications (e.g.

A pragmatic harm reduction approach to manage a large outbreak of wound botulism in people who inject drugs, Scotland 2015 [PDF]
Background People who inject drugs (PWID) are at an increased risk of wound botulism, a potentially fatal acute paralytic illness. During the first 6 months of 2015, a large outbreak of wound botulism was confirmed among PWID in Scotland, which resulted ...

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

Role of Homologous Fc Fragment in the Potency and Efficacy of Anti‐Botulinum Antibody Preparations
The only approved treatment for botulism relies on passive immunity which is mostly based on antibody preparations collected from hyper‐immune horses. The IgG Fc fragment is commonly removed from these heterologous preparations to reduce the incidence of

Evaluating the Potential for Cross-Interactions of Antitoxins in Type II TA Systems
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 mazEF toxin-antitoxin system as a novel antibacterial target in Acinetobacter baumannii [PDF]
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.

Geometric Properties of Isostables and Basins of Attraction of Monotone Systems [PDF]
In this paper, we study geometric properties of basins of attraction of monotone systems. Our results are based on a combination of monotone systems theory and spectral operator theory.

Diverse genetic contexts of HicA toxin domains propose a role in anti-phage defense
Toxin–antitoxin (TA) modules are prevalent in prokaryotic genomes, often in substantial numbers. For instance, the Mycobacterium tuberculosis genome alone harbors close to 100 TA modules, half of which belong to a singular type.
