Grasshopper mouse can ward off pain from a scorpion sting

Grasshopper mouse can ward off pain from a scorpion sting

Dhaka the 28th Oct., ’13. In a research article entitled, “Voltage-Gated Sodium Channel in Grasshopper Mice Defends Against Bark Scorpion Toxin,” published in the 25th October issue of Science (pp. 441-446), Ashlee H. Howe and her four associates at Neurobiology section affiliated at UT Austin and three other institutes have shown that grasshopper mice which live in the Mexican and a part of the South Western USA desert can tolerate painful venoms of scorpion bite. They shrug off the searing sting of the bark scorpion, which cause excruciating pain on the victim: house mice, rats, humans. Grasshopper mice have solved the predator-pain problem by using a toxin bound to a non-target channel to block transmission of the pain signals the venom itself is initiating. This sensational finding, could offer fresh leads for designing painkillers with limited side effects.
