Everything you need to know about Botox
Botox is used medically to treat certain muscular conditions, and cosmetically to remove wrinkles by temporarily paralyzing muscles. It is made from a neurotoxin called botulinum toxin that is produced by the bacterium Clostridium botulinum.
Clostridium botulinum, the bacterium from which Botox is derived, is found in many natural settings, including soil, lakes, and forests.
 
The bacterium can also be found in the intestinal tracts of mammals and fish and in the gills and organs of crabs and other shellfish.
 
Such naturally occurring instances of Clostridium botulinum bacteria and spores are generally harmless. Problems only arise when the spores transform into vegetative cells and the cell population increases.
 
At a certain point, the bacteria begin producing botulinum toxin, the deadly neurotoxin responsible for botulism.
 
Neurotoxins target the nervous system, disrupting the signaling processes that allow neurons to communicate effectively.

Botulinum toxin is one of the most poisonous substances known to man. Scientists have estimated that a single gram could kill as many as 1 million people and a couple of kilograms could kill every human on earth.

 

In high concentrations, botulinum toxin can result in botulism, a severe, life-threatening illness. Botulism, left untreated, may result in respiratory failure and death. Despite botulinum toxin being so toxic, Botox is in huge demand.

 

Despite this, botulinum toxin has proven to be a successful and valuable therapeutic protein.

 

Botulinum toxin can be injected into humans in extremely small concentrations and works by preventing signals from the nerve cells reaching muscles, therefore paralyzing them.

 

In order for muscles to contract, nerves release a chemical messenger, acetylcholine (a neurotransmitter), at the junction where the nerve endings meet muscle cells. Acetylcholine attaches to receptors on the muscle cells and causes the muscle cells to contract or shorten.

 

Injected botulinum toxin prevents the release of acetylcholine, preventing contraction of the muscle cells. Botulinum toxin causes a reduction in abnormal muscle contraction, allowing the muscles to become less stiff.
