The poison of “ the only monkey with poison '' turned out to be almost the same as the causative substance of cat allergy

Cat allergy is a condition in which the eyes become itchy or runny when the cat is touched or approached, and certain proteins in the dandruff and saliva of the cat cause it.Allergen) Is said to be caused. Such cat allergy allergen is known as “ the only monkey with poison ''Slow lorisIt was found that it was also contained in the poison.

Primate venom sheds light on why so many people suffer cat allergies
Slow loris, a member of the primate loris family, are distributed from Central Asia to Southeast Asia and are the only primates known to release poisons. It is said that the poison released from the inside of the elbow by slow loris is effective in preventing parasites by mixing it with saliva and applying it to the whole body, but the specific components and properties of the poison have not been elucidated.

It seems that humans bitten by slow loris may have symptoms similar to cat allergies, and associate professor Brian Fry of the University of Queensland who studies slow loris has long been linked to slow loris poison and cat allergy.Assertionwas doing.
So, a research team led by Associate Professor Frey analyzed the DNA sequence related to the protein contained in the slow loris venom, and found that the protein “Fel d 1Was found to be almost identical to the DNA sequence expressing This proved that the protein contained in the slow loris venom and Fel d 1 had almost the same molecular structure, confirming the assertion of Associate Professor Fry.
In some people, this Fel d 1 becomes an allergen and causes cat allergy. In other words, the allergic reaction that appears in slow loris is almost the same as cat allergy. Associate Professor Fly thinks that “ slow loris poisons his body to protect himself '' and speculates that cats will also release dandruff including Fel d 1 as a similar defense system to slow loris. I am.
Slow loris and cats are on different evolutionary lines, but both express Fel d 1 during evolution.Natural selectionAssuming that the cat and the slow loris have allergic reactions to cat dandruff and slow loris venom, it is assumed that cats and slow loris evolve to attack the human immune system through evolution. Associate Professor Fry argues that it could be.
“ Cats and slow loris may have evolved toxic defensive weapons to keep predators as far away as possible, '' said Associate Professor Fly, and the results of this study further study allergies to other organisms. Said to be interesting.
