TOXIN-ANTITOXIN REACTION WITHOUT NEUTRALIZATION [PDF]

Journal of Experimental Medicine, 1932
1. Collodion particles adsorb diphtheria or tetanus or botulinus toxins. These toxins are retained on the particles when washed but are at least in part released in the animal. 2. The adsorbed toxins are neutralized by adsorption of the corresponding antitoxins but are unaffected by other serums. 3.

Toxin-Antitoxin Systems as Multilevel Interaction Systems

Toxins, 2014
Toxin-antitoxin (TA) systems are small genetic modules usually composed of a toxin and an antitoxin counteracting the activity of the toxic protein. These systems are widely spread in bacterial and archaeal genomes.

A novel type I toxin-antitoxin system modulates persister cell formation in Staphylococcus aureus

International Journal of Medical Microbiology, 2020
A plethora of toxin-antitoxin systems exist in bacteria and has multilateral roles in bacterial pathogenesis and virulence. Toxin-antitoxin systems have been involved in persister cell formation in Escherichia coli and Mycobacterium but have not been ...

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 ...

Performance of pyDock in 8th CAPRI: Energy‐Based Scoring Applied to Docking and AlphaFold Models

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The 8th CAPRI edition has shown a significant evolution in the field of protein–protein complex structure prediction. We have participated in all 11 targets proposed in this edition, involving domain‐domain, protein–protein, protein‐peptide, and protein‐DNA interactions, including homo‐ and hetero‐meric interfaces.

Oral Phageome as Potential Modulators of Periodontal Dysbiosis. A Systematic Review

Oral Diseases, EarlyView.
ABSTRACT Introduction The oral phageome, comprising bacteriophages inhabiting the oral cavity, has been proposed as a potential modulator of periodontal health and disease. This systematic review synthesizes current evidence on interactions between bacteriophages, key periodontal bacteria, and the host in periodontitis.

TOXIN-ANTITOXIN IMMUNIZATION AGAINST DIPHTHERIA [PDF]

JAMA: The Journal of the American Medical Association, 1922
The development of antitoxin in the bodies of animals injected with diphtheria toxin is one of the best established of facts. Since von Behring and Roux announced the results of their investigations, large numbers of horses have been injected with toxin and have developed abundant antitoxin.

Characterization of HicAB toxin-antitoxin module of Sinorhizobium meliloti

BMC Microbiology, 2019
Background Toxin-antitoxin (TA) systems are little genetic units generally composed of two genes encoding antitoxin and toxin. These systems are known to be involved in many functions that can lead to growth arrest and cell death.

The 3D genome of Gigaspora margarita unveils stable chromatin and nucleolar organization and symbiont‐dependent genome dynamics

New Phytologist, Volume 251, Issue 5, Page 2799-2817, September 2026.
Summary Arbuscular mycorrhizal fungi (AMF) are widespread plant symbionts that enhance nutrient acquisition and influence ecosystem productivity. Previous chromosome‐level assemblies of the model species Rhizophagus irregularis revealed a two‐compartment genome architecture (active A and repressed B chromatin compartments), yet its conservation across ...
