Trypanosoma cruzi is the causative agent of Chagas disease. The only two drugs accepted for the treatment of this infection are benznidazole and nifurtimox, which are of limited use in the predominant chronic phase. On the search for new drugs, the intracellular Ca2+ regulation has been postulated as a possible target, due to differences found between host cells and the parasite. The mechanisms involved...
Bactridine 2 (Bact-2) is an antibacterial toxin from Tityus discrepans venom which modifies isoforms 1.2, 1.4 and 1.6 voltage-dependent sodium (Nav) channels. Bactridine-induced Na+ outflow in Yersinia enterocolitica was blocked by amiloride, suggesting that Bact-2 effect was mediated by an amiloride sensitive sodium channel. In this study we show that Bact-2 increases also an outward rectifying current...
