Scorpion Peptides: Potential Use for New Drug Development

Journal of Toxicology, Volume 2013, Issue 1, 2013., 2013
Several peptides contained in scorpion fluids showed diverse array of biological activities with high specificities to their targeted sites. Many investigations outlined their potent effects against microbes and showed their potential to modulate various biological mechanisms that are involved in immune, nervous, cardiovascular, and neoplastic diseases.

Scorpion Venom and the Inflammatory Response

Mediators of Inflammation, Volume 2010, Issue 1, 2010., 2010
Scorpion venoms consist of a complex of several toxins that exhibit a wide range of biological properties and actions, as well as chemical compositions, toxicity, and pharmacokinetic and pharmacodynamic characteristics. These venoms are associated with high morbility and mortality, especially among children. Victims of envenoming by a scorpion suffer a

Scorpions from the primeval subgenus Archaeotityus produce putative homologs of Tityus serrulatus toxins active on voltage-gated sodium channels

Journal of Venomous Animals and Toxins including Tropical Diseases, 2012
It has been proposed that the subgenus Archaeotityus comprises the most ancient species group within the medically important scorpion genus Tityus. cDNA encoding sodium-channel active toxins from the type species of this subgenus, Tityus clathratus ...

Immunomodulatory Effects of the Tityus serrulatus Venom on Murine Macrophage Functions in Vitro

Mediators of Inflammation, Volume 2005, Issue 1, Page 39-49, 2005., 2005
Tityus serrulatus scorpion venom (TSV) consists of a very complex mixture of molecules and demonstrates significant immunomodulatory activities capable of stimulating immune functions in vivo. The purpose of this study was to compare the crude TSV with fractionated toxins extracted from this venom in order to determine which toxin(s) presented ...

Effect of Tityus serrulatus venom on cytokine production and the activity of murine macrophages

Mediators of Inflammation, Volume 11, Issue 1, Page 23-31, 2002., 2002
The purpose of this study was to investigate the effects of Tityus serrulatus venom (TSV) on murine peritoneal macrophages evaluated in terms of activation. The effects of crude TSV were analysed by detection of cytokines, oxygen intermediate metabolites (H2O2) and nitric oxide (NO) in supernatants of peritoneal macrophages.

Record of predation of the Brazilian yellow scorpion Tityus serrulatus (Buthidae) by the toad Rhinella diptycha (Bufonidae) in an urban area in southeastern Brazil

Acta Biológica Colombiana
Tityus serrulatus is one of the main causes of scorpionism in southeastern Brazil. However, little is known about its natural enemies, especially in urban areas, where this species is a major public health concern.
