Analgesics from the gene are insensitive to pain

Genetic mutations can cause some people to not feel pain. This inspired scientists to create new painkillers.

>>>Strange girl disease: Never know pain

Congenital insensitivity to pain (CIP) is an extremely rare disease, so far the world medicine has recorded about 20 cases of people suffering from this disease. They can feel the touch but do not feel pain. This makes them often injured, especially burns because they cannot feel the heat.

According to New Scientist, scientists at the University Hospital Jena, Germany, conducted a comparison of the girl's gene without feeling the natural pain with the genes of her parents, who do not suffer from this disease. After comparison, Dr. Ingo Kurth and his colleagues found a change in the girl's SCN11A gene .

This change means that signals are not transmitted to the organ of the pain sensory organ in the brain. As a result, the girl's body cannot feel pain. To confirm the hypothesis is correct, scientists conducted a study on mice.

The team created mice with mutated SCN11A genes and then tested their ability to feel pain. Scientists found that mice were genetically modified or injured more than normal mice. Mice that change genes also respond to slow pain when their tail is exposed to hot light.

Scientists hope, the discovery could lead to the introduction of new types of pain relief, working by preventing all signals of pain.
