Botulinum toxin nerve block mechanism, illustration
Bildnummer 12583352
| Botulinum toxin nerve block mechanism. Cutaway illustration of part of a nerve axon and the mechanism by which the botulinum toxin (green) causes nerve paralysis. The toxin is shown bound to a vesicle (sphere) of the neurotransmitter acetylcholine, with ion channels (blue) in the membrane also shown. The mechanism involves SNARE proteins (not shown) that act at the synaptic junction (not shown) at the terminal end of the axon to promote the successful release of acetylcholine. The toxin breaks these SNARE proteins, preventing the release of acetylcholine and resulting in paralysis of muscles and nerves. This can be swiftly fatal, but is also used in small amounts in medicine. | |
