Dawson [creativecommons license] from Wikimedia CommonsNatural toxins, such as snake venom, are used by various organisms for protection against potential predation. These toxins work by creating irritation, disease or pain in predators. Their mechanisms of action are of interest to researchers because they may elucidate new or poorly understood biological processes, such as those involved in pain sensation, nerve activation or cardiovascular regulation. Deeper understanding of these pathways may lead to new or improved treatments or management strategies for pain and irritation.
