This finding was recently made by researchers and may help improve treatments for burn pain.
It was an international team of researchers who discovered that one of the toxins in the venom of the tarantulas completely disables the channel that is used by neurons in order to transmit the pain to the brain. This discovery will help improve the treatments against pain caused by burns, and pain is the warning that tells us that something is not right in our body.
The human body is replete with nerve endings specialized in transmitting pain (nociceptors) that, upon detecting a blow, cut or burn, activate and send this information by way of electrical impulse to the spinal cord. Once in the medulla, a second neuron interprets all this information received and sends it back to the brain, where it translates into pain, which we feel.
“If we can modify or restrain the first connection between the nocicetors and the spinal cord, the information does not reach the brain and, therefore, there would be no sensation of pain”, José Vicente Torres, the first author of this study Imperial College London.
All this research, which has just been published in the Journal of Molecular Medicine, focused on the pain caused by burns because it is “an extremely intense and lasting pain”.
These animals, the tarantulas, are characterized by having long legs with two claws at the tip, and a body covered with bristles. They inhabit the temperate and tropical regions of the Americas, Asia, Africa and the Middle East. Its venom is not lethal to humans, and it has already been proven scientifically that it can, as evidenced by this finding, also provide quite beneficial results for the development of alternative medicines and chemicals in the treatment of diseases in humans.
