Observations on the preparation of toxin-antitoxin mixture [PDF]
Journal of Infectious Diseases, 1922 Immunization against diphtheria by toxin-antitoxin has been eminently successful, and this means that another milestone has been passed in the efforts to eradicate the disease. Successful immunization depends on proper balance of toxin and antitoxin.

Stay or Go: Sulfolobales Biofilm Dispersal Is Dependent on a Bifunctional VapB Antitoxin
mBio, 2023 A type II VapB14 antitoxin regulates biofilm dispersal in the archaeal thermoacidophile Sulfolobus acidocaldarius through traditional toxin neutralization but also through noncanonical transcriptional regulation.

Macromolecular High‐Affinity Binding Probed by Advanced Fluorescence Techniques
ChemBioChem, EarlyView.For interacting biomolecules in solution, confocal fluorescence microscopy enables some very effective approaches to characterize intermolecular binding in complex sample environments and with small sample consumption. These approaches range from fluorescence‐based genetically encoded biosensors for use in living cells to the high controllability in ...

RNA Regulated Toxin-Antitoxin Systems in Pathogenic Bacteria
Frontiers in Cellular and Infection Microbiology, 2021 The dynamic host environment presents a significant hurdle that pathogenic bacteria must overcome to survive and cause diseases. Consequently, these organisms have evolved molecular mechanisms to facilitate adaptation to environmental changes within the ...

iMeta, EarlyView.In this study, we reveal that macrophage‐derived reactive oxygen species (ROS) can trigger the rapid formation of Salmonella aggresomes, which substantially contribute to the increased frequency of persisters induced by phagocytosis. Salmonella containing aggresomes exhibited a dormant phenotype characterized by reduced adenosine triphosphate (ATP ...

Hypothetical Functions of Toxin-Antitoxin Systems [PDF]
Journal of Bacteriology, 2007 Toxin-antitoxin systems are very commonly found both on large, low-copy plasmids, where they increase effective stability ([35][1]), and on bacterial chromosomes, where their function has been the subject of considerable speculation.
