An antitoxin is an antibody with the ability to neutralize a specific toxin. Antitoxins are produced by certain animals, plants, and bacteria in response to toxin exposure. Although they are most effective in neutralizing toxins, they can also kill bacteria and other microorganisms.
2 janv. 2022 · Toxin–antitoxin systems are composed of a toxin that inhibits an essential cellular process and an antitoxin that counteracts its cognate toxin. In this Review, Van Melderen and colleagues ...
Une antitoxine est un anticorps ayant la capacité de neutraliser une toxine spécifique. Les antitoxines sont produites par certains animaux, plantes et bactéries .
7 juil. 2021 · Toxin-antitoxin (TA) modules are ubiquitous gene loci among bacteria and are comprised of a toxin part and its cognate antitoxin part. Under normal physiological conditions, antitoxin counteracts the toxicity of the toxin whereas, during stress conditions, TA modules play a crucial role in bacterial physiology through involvement in ...

Anticorps sécrété par les lymphocytes B (cellules du système immunitaire) au contact d'une toxine bactérienne et doué du pouvoir de la neutraliser. Les antitoxines ont été découvertes, en 1890, par le médecin et bactériologiste allemand Emil von Behring et le médecin japonais Shibasaburo Kitasato.
Antitoxin is an antibody that neutralizes a bacterial or venomous toxin. Learn how antitoxins are produced, discovered, and applied in medicine and immunology from Britannica's experts.
Antitoxins of type I and type III are RNA molecules that regulate the cellular levels of active toxin protein either by inhibiting translation of the toxin mRNA (type I) or through direct inhibition of the toxin protein (type III).
