Botulinum Toxin A Mechanism Of Action (Explained)

⌚️ Got only 60 seconds?
Botulinum toxin acts by binding presynaptically to high-affinity recognition sites on the cholinergic nerve terminals and decreasing the release of acetylcholine, causing a neuromuscular blocking effect. This mechanism laid the foundation for the development of the toxin as a therapeutic tool.

3Where Does Botulinum Toxin Type A Act??

[6] Botulinum toxins act at four different sites in the body: The neuromuscular junction, autonomic ganglia, postganglionic parasympathetic nerve endings and postganglionic sympathetic nerve endings that release acetylcholine.

4How Does Botox Botulinum Toxin Work??

Botox injections block certain chemical signals from nerves, mostly signals that cause muscles to contract. The most common use of these injections is to temporarily relax the facial muscles that cause wrinkles in the forehead and around the eyes.
