1What Does Botox Do To Acetylcholine??

Botulinum toxin works by blocking the release of acetylcholine from presynaptic motor neurons, and this chemical denervation causes a cascade of downstream events in the muscle thus causing muscle paralysis16.

2How Does Botox Affect The Synapse??

Botulinum toxins (BoNT) induce a relative muscle weakness by cleaving components of the presynaptic soluble NSF attachment protein receptor (SNARE) complex (essential for vesicular fusion), resulting in a significant reduction of acetylcholine release in the synaptic cleft (Malaty and Akbar, 2014).

3Does Botulinum Toxin Inhibit Ach Release?

Clostridium botulinum type toxin A (BoTx) blocks stimulus-induced acetylcholine (ACh) release from presynaptic nerve terminals at peripheral neuromuscular junctions. However, the detailed mechanism of this effect remains elusive.

4What Prevents Acetylcholine Release?

Botulinum toxin works by preventing acetylcholine release from the presynaptic terminals.

5How Does Botox Prevent Neurotransmitter Release?

Through their proteolytic action on these proteins, botulinum toxins prevent exocytosis, thereby inhibiting the release of acetylcholine. There are 7 serotypes of this toxin-A, B, C1, D, E, F, and G-and each cleaves a different intracellular protein or the same target at distinct bonds.

6What Neurotransmitter System Does Botox Alter?

Botulinum toxin acts at the neuromuscular junction (motor plaque) blocking the release and effects of acetylcholine (ACh), a neurotransmitter of both the central nervous system (CNS) and the peripheral nervous system (SNP).

7What Does Botulinum Toxin Do To Neurons?

Botulinum neurotoxins (BoNTs) are the most toxic proteins known, due to inhibiting the neuronal release of acetylcholine and causing flaccid paralysis. Most BoNT serotypes target neurons by binding to synaptic vesicle proteins and gangliosides via a C-terminal binding sub-domain (HCC).
