Western diamondback rattlesnake blood contains FETUA proteins that can neutralize different venom toxins when combined in precise mixtures. Optimized protein combinations completely protected laboratory mice from several viper venoms and were up to 10 times more potent by weight than commercial CroFab antivenom. The findings could support safer, cheaper recombinant antivenoms, but researchers must still prove the treatment works after a bite and against additional toxin families.

Carroll University of Maryland researchers discovered a new approach to treating venomous snakebites—using the same toxin-blocking proteins that snakes evolved to protect themselves. The team found that specific combinations of blood proteins from western diamondback rattlesnakes provided unprecedented neutralizing power against the venom of multiple dangerous snake species. The research, led by Professor of Biology Sean B.

Credit: Gerald Wilkinson A new study of wild bats reveals that an animal's immune system is shaped by more than its need to fight infections. Researchers from the University of Maryland have found that sex, age and competition for mates influence how bats balance different types of immune defenses—providing new insight into how evolutionary pressures shape immune strategy.
