Toxin-antitoxin systems as phage defense elements

M LeRoux, MT Laub - Annual Review of Microbiology, 2022 - annualreviews.org
Toxin-antitoxin (TA) systems are ubiquitous genetic elements in bacteria that consist of a
growth-inhibiting toxin and its cognate antitoxin. These systems are prevalent in bacterial …

Bacterial persisters: molecular mechanisms and therapeutic development

H Niu, J Gu, Y Zhang - Signal transduction and targeted therapy, 2024 - nature.com

bacteria that survive in stress environments such as antibiotic exposure, acidic and …

Type II toxin-antitoxin systems: evolution and revolutions

N Fraikin, F Goormaghtigh… - Journal of …, 2020 - Am Soc Microbiol
Type II toxin-antitoxin (TA) systems are small genetic elements composed of a toxic protein
and its cognate antitoxin protein, the latter counteracting the toxicity of the former. While TA …

Ciprofloxacin Causes Persister Formation by Inducing the TisB toxin in Escherichia coli

T Dörr, M Vulić, K Lewis - PLoS biology, 2010 - journals.plos.org
Bacteria induce stress responses that protect the cell from lethal factors such as DNA-
damaging agents. Bacterial populations also form persisters, dormant cells that are highly …

A primary physiological role of toxin/antitoxin systems is phage inhibition

S Song, TK Wood - Frontiers in Microbiology, 2020 - frontiersin.org
Toxin/antitoxin (TA) systems are present in most prokaryote genomes. Toxins are almost
exclusively proteins that reduce metabolism (but do not cause cell death), and antitoxins are …

RETRACTED: Bacterial persistence by RNA endonucleases

E Maisonneuve, LJ Shakespeare… - Proceedings of the …, 2011 - pnas.org
Bacteria form persisters, individual cells that are highly tolerant to different types of
antibiotics. Persister cells are genetically identical to nontolerant kin but have entered a …

Toxin-antitoxin systems influence biofilm and persister cell formation and the general stress response

X Wang, TK Wood - Applied and environmental microbiology, 2011 - Am Soc Microbiol
In many genomes, toxin-antitoxin (TA) systems have been identified; however, their role in
cell physiology has been unclear. Here we examine the evidence that TA systems are …
