Cone venom--from accidental stings to deliberate injection

Cone snails have long been of note due to their colorful shells and deadly venom. Over the years, a number of people who have encountered these molluscs have been injured or killed by their sting. Biochemical analysis of the venom components has revealed a plethora of peptides and proteins that target a variety of receptors and ion channels. Pharmaceutical companies are now utilizing the selectivity and potency of Conus-derived peptides to develop novel medications for pain, epilepsy and other disorders.
