Scorpion Venom: Detriments and Benefits
Scorpion venom may cause severe medical complications and untimely death if injected into the human body. Neurotoxins are the main components of scorpion venom that are known to be responsible for the pathological manifestations of envenoming.

The envenomation of general physiology throughout the last century. [PDF]
Toxins are the poisonous products of organisms. Toxins serve vital defensive and offensive functions for those that harbor them: stinging scorpions, pesticidal plants, sanguinary snakes, fearless frogs, sliming snails, noxious newts, and smarting spiders.

Subtype Specificity of β-Toxin Tf1a from Tityus fasciolatus in Voltage Gated Sodium Channels
Scorpion venoms are a complex mixture of components. Among them the most important are peptides, which presents the capacity to interact and modulate several ion channel subtypes, including voltage-gated sodium channels (NaV).

Genomic organization of the KTX2 gene, encoding a `short' scorpion toxin active on K+ channels [PDF]
A single intron of 87 bp, close to the region encoding the C-terminal part of the signal peptide, was found in the gene of the `short' scorpion toxin kaliotoxin 2 of Androctonus australis acting on various types of K+ channels.

The scorpion Toxin Tf2 from Tityus fasciolatus Promotes Nav1.3 opening [PDF]
We identified Tf2, the first β-scorpion toxin from the venom of the Brazilian scorpion Tityus fasciolatus. Tf2 is identical to Tb2-II found in Tityus bahiensis.We found that Tf2 selectively activates human (h)Nav1.3, a neuronal voltage-gated sodium (Nav)

Neurotransmitter evaluation in the hippocampus of rats after intracerebral injection of TsTX scorpion toxin [PDF]
TsTX is an a-type sodium channel toxin that stimulates the discharge of neurotransmitters from neurons. In the present study we investigated which neurotransmitters are released in the hippocampus after TsTX injection and if they are responsible for ...

Spider neurotoxins targeting voltage-gated sodium channels [PDF]
The voltage-gated sodium (Nav) channel is a target for a number of drugs, insecticides, and neurotoxins. These bind to at least seven identified neurotoxin binding sites and either block conductance or modulate sodium channel gating and/or kinetics.
