Tityus serrulatus venom – A lethal cocktail

Toxicon, 2015
Tityus serrulatus (Ts) is the main scorpion species of medical importance in Brazil. Ts venom is composed of several compounds such as mucus, inorganic salts, lipids, amines, nucleotides, enzymes, kallikrein inhibitor, natriuretic peptide, proteins with high molecular mass, peptides, free amino acids and neurotoxins. Neurotoxins are considered the most

Neutralizing effects of Mimosa tenuiflora extracts against inflammation caused by Tityus serrulatus scorpion venom. [PDF]

Biomed Res Int, 2014
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.

Toxicity and protein composition of venoms of Hottentotta saulcyi, Hottentotta schach and Androctonus crassicauda, three scorpion species collected in Iran

Veterinary Medicine and Science, Volume 7, Issue 6, Page 2418-2426, November 2021., 2021
This study could be useful for understanding the venom extraction and toxicity, the protein and amino acid diversities of three species of scorpions (Hottentotta saulcyi, Hottentotta schach and Androctonus crassicauda). The results from this study show that H. saulcyi and H.

Mass spectrometry‐based top‐down and bottom‐up approaches for proteomic analysis of the Moroccan Buthus occitanus scorpion venom

FEBS Open Bio, Volume 11, Issue 7, Page 1867-1892, July 2021., 2021
Buthus occitanus scorpion possesses highly toxic venom. This article describes the first proteomic screening of the Moroccan B. occitanus venom. Our findings highlight the complexity and the toxin diversity of this venom. The most representative compounds are neurotoxins.

Proteomic endorsed transcriptomic profiles of venom glands from Tityus obscurus and T. serrulatus scorpions. [PDF]

PLoS ONE, 2018
Except for the northern region, where the Amazonian black scorpion, T. obscurus, represents the predominant and most medically relevant scorpion species, Tityus serrulatus, the Brazilian yellow scorpion, is widely distributed throughout Brazil, causing ...

Reciprocal transplantation of the heterotrophic coral Tubastraea coccinea (Scleractinia: Dendrophylliidae) between distinct habitats did not alter its venom toxin composition

Ecology and Evolution, Volume 10, Issue 4, Page 1794-1803, February 2020., 2020
Toxin complexity in the alien coral Tubastraea coccinea is conserved and co‐evolved with innovation of the venom delivery system. Morphological development of the coral and phenotypic expression of the venom and delivery system is not modulated by habitat pressures over short periods of time.
