The scorpion envenoming syndrome is a serious public health matter in Brazil. Previous results from our laboratory suggest that the effects of scorpion toxins on the central nervous system play a major role on the lethality induced by scorpion envenoming.

We examined the effects of dantrolene, an inhibitor of intracellular calcium release, on alterations associated with the intrahippocampal injection of the TsTX scorpion toxin. Male Wistar rats (230-250 g) were injected with Ringer solution (1 microl; n = 6); TsTX

The interaction between two nonhomologous K+ channel toxins, Tityus serrulatus (scorpion) toxin tityustoxin-K alpha (TsTX-K alpha) and Dendroaspis angusticeps (snake) toxin dendrotoxin (alpha-DTX), was investigated on K+ currents in B82 fibroblast cells transformed to express the Kv1.2 K+ channel.

Two nonhomologous polypeptide toxins, tityustoxin K alpha (TsTX-K alpha) and tityustoxin K beta (TsTX-K beta), purified from the venom of the Brazilian scorpion Tityus serrulatus, selectively block voltage-gated noninactivating K+ channels in synaptosomes (IC50 values of 8 nM and 30

1. We investigated the action of TsTX-Kalpha on cloned Kv1.3 channels of the Shaker subfamily of voltage-gated potassium channels, using the voltage-clamp technique. Highly purified TsTX-Kalpha was obtained from the venom of the Brazilian scorpion Tityus serrulatus using a new
