Tityus serrulatus Scorpion Venom-Induced Nociceptive Responses Depend on TRPV1, Immune Cells, and Pro-Inflammatory Cytokines [PDF]

Toxins
For centuries, researchers have been fascinated by the composition of scorpion venom and its local and systemic effects on humans. During a sting, scorpions inject peptides and proteins that can affect immune cells and neurons.

The role of bromeliad structural complexity on the presence, spatial distribution and predator avoidance in Tityus neglectus (Scorpiones: Buthidae). [PDF]

Ecol Evol
Due to remarkable architectural design featuring rosette‐like leaf arrangements, bromeliads serve as habitats for various species. Bromeliad architecture is a key factor in the spatial distribution and occurrence of the Tityus neglectus scorpion. Furthermore, T.

Bringing order to a complex system: phenotypic and genotypic evidence contribute to the taxonomy of Tityus (Scorpiones, Buthidae) and support the description of a new species [PDF]

ZooKeys, 2021
We present a molecular phylogenetic analysis including a survey for overlooked phenotypic characters. Based on both analysis and characters a new cave-dwelling species is described: Tityus (Tityus) spelaeus sp. nov.

Characterization of the first two toxins isolated from the venom of the ancient scorpion Tityus (Archaeotityus) mattogrossensis (Borelli, 1901)

Journal of Venomous Animals and Toxins including Tropical Diseases, 2021
Background: Almost all Tityus characterized toxins are from subgenera Atreus and Tityus, there are only a few data about toxins produced by Archaeotityus, an ancient group in Tityus genus. Methods: Tityus (Archaeotityus) mattogrossensis crude venom was
