Scientists discover a powerful new antivenom hidden in rattlesnake blood
News
Scientists are turning snakesâ own venom defenses into an antivenom that proved about 10 times more potent than a current treatment in laboratory tests.
– Researchers discovered that combinations of toxin-blocking proteins naturally found in rattlesnake blood can powerfully neutralize venom from several dangerous snake species. In lab tests, the mixtures were about 10 times more potent than a current commercial antivenom, pointing toward a new generation of nature-inspired snakebite treatments.
Details
University of Maryland researchers have identified a promising new way to treat venomous snakebites by borrowing from snakes’ own natural defenses. Their approach uses toxin-blocking proteins that western diamondback rattlesnakes evolved to protect themselves from venom.
By combining specific proteins found in rattlesnake blood, the researchers achieved unusually strong protection against venom from several dangerous snake species.
The study was led by Distinguished University Professor of BiologySean B. Carroll and published in the Proceedings of the National Academy of Sciences. The findings could help researchers develop more powerful antivenoms for deadly snakebites, which remain a major health threat in some regions of the world.
Analysis
“This is one of those great stories when nature has already solved a problem we’ve been grappling with for decades,” said Carroll, who also holds the Andrew and Mary Balo and Nicholas and Susan Simon Endowed Chair at UMD.
The Global Challenge of Snakebites
Snakebite is considered one of the world’s most neglected tropical diseases. According to the World Health Organization, venomous snakes kill an estimated 80,000 to 140,000 people annually, while hundreds of thousands of survivors are left with permanent disabilities. Many of those affected live in rural areas where effective antivenom can be difficult to obtain.
