Insights into the Hypertensive Effects of Tityus serrulatus Scorpion Venom: Purification of an Angiotensin-Converting Enzyme-Like Peptidase
The number of cases of envenomation by scorpions has grown significantly in Brazil since 2007, with the most severe cases being caused by the Tityus serrulatus scorpion. Although envenomed patients mostly suffer neurotoxic manifestations, other symptoms, such as hypertension, cannot be exclusively attributed to neurotoxins. Omics analyses have detected plentiful amounts of metalloproteases in T...
متن کاملAge effects on the pharmacokinetics of tityustoxin from Tityus serrulatus scorpion venom in rats.
The pharmacokinetics of scorpion venom and its toxins has been investigated in experimental models using adult animals, although, severe scorpion accidents are associated more frequently with children. We compared the effect of age on the pharmacokinetics of tityustoxin, one of the most active principles of Tityus serrulatus venom, in young male/female rats (21-22 days old, N=5-8) and in adult ...
متن کاملNeutralizing Effects of Mimosa tenuiflora Extracts against Inflammation Caused by Tityus serrulatus Scorpion Venom
Scorpion bite represents a significant and serious public health problem in certain regions of Brazil, as well as in other parts of the world. Inflammatory mediators are thought to be involved in the systemic and local immune response induced by Tityus serrulatus scorpion envenomation. The aim of this study was to evaluate the effect of extracts of Mimosa tenuiflora on model envenomation. In mi...
متن کاملThe dynamics of cytokine d nitric oxide secretion in mice injected with Tityus serrulatus scorpion venom.
AIMS The effects of Tityus serrulatus venom (TSV) were analysed with respect to the susceptibility of four isogenic mouse, the symptoms following injection of venom and the inflammatory mediators in an experimental model of severe envenomation induced in mice. METHODS The susceptibility was analysed by lethal dose (LD50) determination, including the symptoms observed during envenomating and g...
متن کاملInsights into scorpion venom peptides: Alternative processing of β-KTx propeptide from Tityus serrulatus venom results in a new naturally occurring thimet oligopeptidase inhibitor
Most functions attributed to Tityus serrulatus venom (TsV) are related to active molecules on ion-channels; however, here we describe a new pentapeptide that was discovered through enzymatic assay selection using EP24.15. The primary structure analysis revealed the sequence KEXXG (X means Ile or Leu), similar to the sequence present in the β-KTX propeptide described from the venom of Tityus spp...
