Botulinum Toxin

Botulinum toxin is a neurotoxic protein complex produced by the bacterium Clostridium botulinum and related species. It is one of the most potent biological toxins known.

Serotypes and Research Areas

Seven distinct serotypes of botulinum toxin exist (designated A through G). Types A and B are the most extensively studied. The properties of botulinum toxin are investigated for its ability to cause localized and temporary muscle paralysis by blocking acetylcholine release at neuromuscular junctions.

Research History

Systematic research beginning in the 1970s and 1980s led to the investigation of botulinum toxin for various applications. This work eventually resulted in the regulatory approval of several distinct pharmaceutical formulations, such as onabotulinumtoxinA (Botox®), abobotulinumtoxinA (Dysport®), incobotulinumtoxinA (Xeomin®), and others.

The approval and indications for use apply only to these specific pharmaceutical products and not to this research material.

Botulinum toxin induces its effects through a multi-step process involving neuronal binding, internalization, translocation, and enzymatic cleavage of proteins involved in neurotransmitter release.
