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 nociceptive response induced by different classes of Tityus serrulatus neurotoxins: The important role of Ts5 in venom-induced nociception [PDF]

PLoS Neglected Tropical Diseases, 2023
Scorpion sting envenomations (SSE) are feared by the intense pain that they produce in victims. Pain from SSE is triggered mainly by the presence of neurotoxins in the scorpion venom that modulates voltage-gated ion channels.
