Botulinum toxin , or botulinum neurotoxin (commonly called botox ), is a neurotoxic protein produced by the bacterium Clostridium botulinum and related species.[ 24] It prevents the release of the neurotransmitter acetylcholine from axon endings at the neuromuscular junction , thus causing flaccid paralysis .[ 25] The toxin causes the disease botulism .[ 26] The toxin is also used commercially for medical and cosmetic purposes.[ 27] [ 28] Botulinum toxin is an acetylcholine release inhibitor and a neuromuscular blocking agent.[ 1] [ 23]
The seven main types of botulinum toxin are named types A to G (A, B, C1, C2, D, E, F and G).[ 27] [ 29] New types are occasionally found.[ 30] [ 31] Types A and B are capable of causing disease in humans, and are also used commercially and medically.[ 32] [ 33] [ 34] Types C–G are less common; types E and F can cause disease in humans, while the other types cause disease in other animals.[ 35]
Botulinum toxins are among the most potent toxins known to science.[ 36] [ 37] Intoxication can occur naturally as a result of either wound or intestinal infection or by ingesting formed toxin in food. The estimated human median lethal dose of type A toxin is 1.3–2.1 ng /kg intravenously or intramuscularly , 10–13 ng/kg when inhaled, or 1000 ng/kg when taken by mouth.[ 38]
