Botulinum Neurotoxins
Botulism is a neuroparalytic disease caused by neurotoxin produced from the bacterium Clostridium botulinum. The botulinum neurotoxins (BoNTs) are among the most potent known biological toxins and have an estimated human median lethal dose (LD50) in the nanogram/kilogram range. Botulinum toxins have historically been employed as biological weapons (BW) through state-sponsored programs in Japan,...
متن کاملTherapeutic applications of botulinum neurotoxins in head and neck disorders.
OBJECTIVE The aim of this article is to review the mechanism of action, physiological effects, and therapeutic applications of botulinum neurotoxins in the head and neck area. STUDY DESIGN An extensive literature search was performed using keywords. The resulting articles were analyzed for relevance in four areas: overview on botulinum neurotoxins, the role of botulinum neurotoxins in the man...
متن کاملBotulinum Neurotoxins and Botulism: A Novel Therapeutic Approach
Specific treatment is not available for human botulism. Current remedial mainstay is the passive administration of polyclonal antibody to botulinum neurotoxin (BoNT) derived from heterologous species (immunized animal or mouse hybridoma) together with supportive and symptomatic management. The antibody works extracellularly, probably by blocking the binding of receptor binding (R) domain to the...
متن کاملAntipruritic Effects of Botulinum Neurotoxins.
This review explores current evidence to demonstrate that botulinum neurotoxins (BoNTs) exert antipruritic effects. Both experimental and clinical conditions in which botulinum neurotoxins have been applied for pruritus relief will be presented and significant findings will be highlighted. Potential mechanisms underlying antipruritic effects will also be discussed and ongoing challenges and unm...
متن کاملZebrafish Sensitivity to Botulinum Neurotoxins.
Botulinum neurotoxins (BoNT) are the most potent known toxins. The mouse LD50 assay is the gold standard for testing BoNT potency, but is not sensitive enough to detect the extremely low levels of neurotoxin that may be present in the serum of sensitive animal species that are showing the effects of BoNT toxicity, such as channel catfish affected by visceral toxicosis of catfish. Since zebrafis...
