Cone snail venom may offer a new approach to treating severe pain according to researchers at the University of Utah.
"We found a new way to treat a chronic and debilitating form of pain suffered by hundreds of millions of people on Earth," says J. Michael McIntosh, a University of Utah research professor of biology. "It is a previously unrecognized mechanism for treating pain."
The research, published in the Nov. 13 in the online edition of the journal Proceedings of the National Academy of Sciences, found that cone snail can treat nerve hypersensitivity and pain by blocking the "alpha9alpha10 nicotinic acetylcholine receptor" molecule in cells.

"The numerous analgesic compounds currently available are largely ineffective" for chronic nerve pain, write McIntosh and his colleagues. "Our findings not only suggest a previously unrecognized molecular mechanism for the treatment of neuropathic pain, but also demonstrate the involvement of alpha9alpha10 nicotinic receptors" in nerve injury.
McIntosh says that any medication derived from the research is, at minimum, ten years away.
