Passive Immunisation in the Treatment of Infectious Diseases Related to Highly Potent Bacterial Toxins [PDF]

open access: yesBiomedicines
The discovery of microbial toxins as the primary factors responsible for disease manifestations and the discovery that these toxins could be neutralised by antitoxins are linked to the birth of immunology. In the late 19th century, the serum or plasma of

Dynamics-Based Regulatory Switches of Type II Antitoxins: Insights into New Antimicrobial Discovery

open access: yesAntibiotics, 2023
Type II toxin-antitoxin (TA) modules are prevalent in prokaryotes and are involved in cell maintenance and survival under harsh environmental conditions, including nutrient deficiency, antibiotic treatment, and human immune responses. Typically, the type

Bioinformatic exploration reveals features of tenpIN family of type III toxin-antitoxin systems in bacteria and viruses [PDF]

open access: yesScientific Reports
Toxin-antitoxin (TA) systems in bacteria consist of two genes: one encoding a toxin that inhibits essential cellular processes and the other encoding an antitoxin that neutralizes the toxin under homeostatic conditions.

Novel type II toxin-antitoxin systems with VapD-like proteins [PDF]

open access: yesmBio
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.

Free-Living Bacteria May Utilize Chromosomal Toxin–Antitoxin Systems to Mediate K Sensing and Control by Continuously Modulating the Ratio of Injury: Repair Throughout the Life Cycle [PDF]

open access: yesToxins
A recent publication proposed that the main biological function of chromosomal toxin–antitoxin systems (TASs) in free-living bacteria is to optimize fitness by mediating K Sensing and Control via a Nutrient-Responsive Cybernetic System.

Induced DNA bending by unique dimerization of HigA antitoxin

open access: yesIUCrJ, 2020
The bacterial toxin–antitoxin (TA) system regulates cell growth under various environmental stresses. Mycobacterium tuberculosis, the causative pathogen of tuberculosis (TB), has three HigBA type II TA systems with reverse gene organization, consisting ...

Stay or Go: Sulfolobales Biofilm Dispersal Is Dependent on a Bifunctional VapB Antitoxin

open access: yesmBio, 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.

Clinical cases of atypical and severe botulism

open access: yesZaporožskij Medicinskij Žurnal, 2020
The aim of the work was to present two clinical cases of botulism: the atypical course and the severe course with late administration of heptavalent botulinum antitoxin, which still had a significant positive clinical effect and contributed to a faster ...
