Neurotoxin
Definition:
Neurotoxins are chemical molecules that have an adverse effect on neuron function and, thus, disrupt the normal function of the nervous system. Neurotoxins could be small molecules or peptides and can be derived from a variety of invertebrate and vertebrate animals, as well as plant species.The following is a short list of some examples of neurotoxins:
α-Bungarotoxin: A peptide neurotoxin that inhibits the nicotinic acetylcholine receptor.
Chlorotoxin: A peptide neurotoxin that inhibits chloride channels.
α-Conotoxin: A peptide neurotoxin that inhibits the nicotinic acetylcholine receptor.
δ-Conotoxin: A peptide neurotoxin that inhibits voltage-gated sodium channels.
w-Conotoxin: A peptide neurotoxin that inhibits N-type voltage-gated calcium channels.
Picrotoxin: Inhibits GABAA receptor chloride channels.
Tetrodotoxin: Inhibitor of neuronal voltage-gated sodium channels.
