Botulinum toxin type a wiki. Botulinum Toxin A (BoNT-A) is a neurotoxin derived from the bacterium Clostridium Botulinum. Clostridum neurotoxins are produced as a single inactive polypeptide chain of 150 kDa, which is cleaved by tissue proteinases into an active di-chain Botulinum toxin cũng được sử dụng để điều trị các rối loạn của dây thần kinh hiếu động bao gồm đổ mồ hôi quá mức, đau thần kinh, và một số bệnh dị ứng. There are 7 known immunologically distinct serotypes of BoNT: types A, B, C1, D, E, F, and G. Each entry includes links to find associated clinical trials.

Along with Apr 5, 2013 · Abstract Botulinum toxin (BoNT) is a potent neurotoxin that is produced by the gram-positive, spore-forming, anaerobic bacterium, Clostridum botulinum. [23] Botulinum toxin type A is a purified form of botulinum toxin type A used to block acetylcholine release in the treatment of chronic sialorrhea, muscle spasticity, and dystonia, as well as in cosmetic applications. [2][3] C. Botulinum toxin is in the neurotoxin class of medications. Medicinal uses include chronic migraine, spastic disorders, cervical dystonia, and detrusor hyperactivity. BT, or Botox, is defined as a commercially available serotype of botulinum toxin A produced by Clostridium botulinum, which acts as a zinc protease that inhibits acetylcholine release at the neuromuscular junction, leading to muscle denervation and temporary paralysis. It has been purified under very strictly controlled conditions to treat a variety of hyperactive muscle disorders. They are synthesized as a single inactive polypeptide chain of 150 kDa complexed with non-neurotoxic components and released by bacterial lysis.
