Neurotoxins from Snake Venom

Abstract

Found within snake venoms are a variety of toxic and nontoxic proteins. The effects of snake venoms depend on all of the components of that venom. However, the lethal effects are usually related to the most potent toxins found within the venom; the two most toxic proteins found in snake venom are neuro- and cardiotoxins. This article reviews a variety of neurotoxins found in snake venom. The range of neurotoxins present in snake venom is varied and includes: peripheral and noncentral, presynaptic, postsynaptic, potassium-channel inhibiting, muscarinic transmission inhibiting, and anticholinesterase types.
